i haven't said it before but why is it still the neighbour's cat and not your cat
how to stop neighbour cat from loving me so much so I can use computer
#also as a person with own cat who loves me too much to let me use the computer#see if you can get one of those cat toys that are basically a handle + a long and flexible antenna (? wire?) with a dongle at the end#stick the handle in your waistband or pocket when you sit down so that the dongle dangles behind you and wiggle in place#cat will play at your back and let you have keyboard access

Finally finishing all these guys we’ve got charts and headcanons! (Long post)
(Height)
(Wingspan)
(Body length & basic shapes I used) (it might be odd but ignore any detail on the back, the shapes are for general body shape)
Headcanons:
Seawings: - Colors range from red and purple to yellow - Aquatic is based off areas of bioluminescence rather than singular scales (because no one wants to draw all of those) - Although they average small compared to the other tribes, gigantism is more common - Wing bioluminescence gene is always present but for some doesn't show, thus aquatic doesn't utilize the wings
Rainwings: - Can change the texture of their scales alongside color - Weakest bite due to their fangs, probably why they're vegetarian - Mimic interesting behaviors - Have forked tongues
Mudwings: - Colors range from olive green to purple-ish red - Very resilient - Able to breathe fire regardless of body temperature, the heat of the flame depends on body temp - Their horns constantly grow and sometimes have to be cut due to dangerous growing patterns - Love gnawing on things, tough foods like jerky is popular - The horn covers of fallen siblings are harvested and turned into instruments to remember them by
Leafwings: - Colors range from gold to teal (and pink to olive green during cold seasons) - Can appear to have false eyes - Bug-like just like the other Pantalan residents (because they're just some weird outlier like what is going on here) - Leafspeak doesn't actually allow them to hear voices from plants but rather increase the sensitivity of their antennae which pick up on the changes in plants - In colder seasons, regions that have deciduous trees influence leafwings in that their scales change into warm tones similar to fallen leaves for camouflage but this also negatively impacts one's leafspeak ability; this doesn't apply to evergreen leafwings however
Hivewings: - Colors range from hot pink to olive green - Can appear to have false eyes - Have elbowed antennae just like their "cousins", Hymenoptera (wasps, bees, ants) - Tend to disregard personal space/get close out of habit, being close means better temp regulation and better communication - All hivewings have stingers, wrist stingers, and a venomous bite but it largely depends on preference of which they choose and like muscles, they can be exercised to become deadly weapons - They're not capable of "emitting a horrible stench"
Icewings: - Colors range from white to pale indigo - Melanism is still very rare but more likely in icewings - Can be iridescent in any color, especially visible in lighter scaled individuals - The scales on their face is very fine and is flushed with blood which darkens the area and allows them to see in the snow by absorbing light, otherwise the glare from the sun reflecting off would be a hinderance - Their wings are thin and thus have visible veins most of the time - Idk how to describe their scales other than its kinda like basalt formations - From the side they appear large but are actually thin and flexible - They can freeze to death if they've gone without cold for a long time and then reintroduced too quickly - In hybridization, they have dominant genes, partially because the animus gene - The extra mane of horns can appear randomly on the body in singular spikes, they also make a clink sound when they collide as if they're made of ice, making a pretty scary rattle when disturbed
Nightwings: - Colors range from orange to purple - Albinism is still very rare but more likely in nightwings - Dwarfism is more common - Teardrop scales are always present, highlighted when the dragon has powers regardless of type - Pitbull ready to bite kids - They CAN hang upside down as the books suggest but not for long - By taking dust baths, they dull their scales to reflect less light and blend in better in the dark - Have white fire but cant breathe for long due to how hot it is (this is mainly to add onto the mysterious factor of em and I always liked the idea) - Due to eye sensitivity, they hate sudden bright lights and will close their eyes as they breathe fire
Silkwings: - Can have black or dark accents but never as a whole body color unless they've hybridized - Wing shapes vary widely - Can appear to have false eyes - Flamesilk is rarer than one might think - Very flexible and have strong tails used as a sort of 5th limb in climbing - Albino or melanistic dragons still keep their iridescence - Silk is emitted through a spinneret on the chin rather than the wrists - Prefer to travel in pairs (instinct)
Sandwings: - Colors range from red to olive green - Dark patters often mimic a snake's - Horse-like in complexion - Alongside their snake-like appearance, they have pit organs - Tend to move like birds - Poor eyesight but good hearing - Their horns angle upwards sort of like a bull
Skywings: - Colors range from red to yellow (and green because skywings are meant to be your typical fire breathing dragon which is most often depicted to be red but can also be green) - Tend to move like birds - Weaker than they appear - Green skywings are incapable of being or having flamescales - Their horns constantly grow and have to be filed down - A flamescale cant melt rock or metal by touch alone, only via fire is it possible - It's not that they don't want flamescales that they kill them, it's more of a mercy killing because of how lonely their life can be

I get the feeling NSH used to have much more flexible antenna and then did something really dumb and they were rendered the way they are today
I've seen some people with the headcanon that he wrecked, cut or removed his antennae! I'm leaning on my NSH just being made that way though. There are other iterators with similarly short antennae, or even no antennae at all.
He doesn't seem to be all too bothered by it in the end. Especially when it leads to opportunities like this...

Some Headcanons about Pantala because AAAASNMSKAKAMA
The mountain range of Pantala is said to be cursed because of the mysterious ruins there, which Wasp destroyed all evidence of. This is because they held the BeetleWing palace. It is generally avoided because of this and because of the extremely harsh conditions.
SilkWings can be (almost) cleanly separated into the more moth-like SilkWings (thicker build, floofier, slightly duller scales, larger wings, but smaller overall) and more butterfly-like SilkWings (slimmer, longer antennae, less flexible wings, curled claws, MUCH flashier colours).
HiveWings aren’t all descended from ClearSight: when ClearSight saved everyone, BeetleWings started trying to have dragonets with more black scales as a tribute to her. The only HiveWings really descended from ClearSight are the royal family: the idea that all HiveWings are her family is (VERY) old propaganda to make HiveWings seem superior.
LeafWings have a weaker version of RainWing photosynthesis.

Dragons of Pantala (headcanon designs)
• Silkwings:
-Inherited from nightwings genes of fur on the chest and in their case they only progressed, thanks to which the wool is distributed throughout the abdomen, neck and front legs
-In addition, the shape of the scales is more like the scales of nightwings than the beetlewings. The hind legs are also inherited from nightwings (in general, silkwings closer to the nightwings while hivewongs to the beetlewings)
-Big Eyes
-Very long tongue
-Mouth are small and round
-Short, round ears
-Teeth are not very sharp, by structure more like the teeth of herbivores than of predators (transitional form from one diet to another; such a structure also came from the merger of nightwings (predators) and beetlewings (omnivorous, but preferring to eat plants; fed only under adverse conditions))
-Blood are beige, semi-transparent
-The shape before and after Metamorphosis is significantly different. The "caterpillars" (before metamorphosis) are covered with blistering scales, some have a greenish tinge, developed a cusptry at the mouth - the mouthparts helps the dragonets to feed (after metamorphosis only small mouthparts remain, which are rather rudimentary), very small antennae on the head, almost not functioning; their role replaces temporary growths on the lower jaw, which disappear after metamorphosis. Body consists of scales, fur missing
-After metamorphosis the skin color becomes much brighter, grow long antennae with fur at the end, also appears directly, the fur itself on some parts of the body
-The shape of the wings in some individuals may be different (similar to the butterfly wings after which they were named)
-Flamesilk dragons have patterns in the form of lights on their wings and also fire colors (red, orange, yellow) all over their body. Eyes are also very bright (before the metamorphosis it is not visible, also in normal silkwings eye color changes slightly, unlike flamesilk dragons). All this is a warning to other creatures that these dragons don't have ordinary silk (it is similar to how in our world poisonous animals have bright, warning coloring)
-Growth reaches 2-2.5 meters
*The design was based on butterflies and their caterpillars
• Hivewings:
-Round tail. Despite its external fleshiness, it is almost completely hollow and not overloaded with internal organs and muscles. It contains only organs of the reproductive system and a reservoir with poison. And even though there are these organs that contribute to the flying, 2 pairs of wings and a dense front of the body all compensate for it, and they restore balance
-The tail itself is motionless, only able to descend, in order to wound the opponent with a dagger. The front part of the body is more flexible.
-Ears are long but thin
-Blood as like silkwings, beige and semi-transparent, but has a darker shade
-The gait is more developed than silkwings
-Paw structure identical to beetlewings
-Thorns on the entire spine fall long, with a sharp end
-Horns are curved, facing the opposite direction
-Whites darkened but not entirely black, has a dark shade of the color of the iris
-Also prefer to eat plants, but unlike silkwings, their teeth are very sharp. The reason is defensive functions, the presence of poison in them.
-Mouth is sharp, triangular shape
-Growth reaches 2.5-3 meters
*The design was based on bees, wasps and some other insects
• Beetlewings:
-Horns curved and parallel to the mouth
-Sharp nose, able to pierce the opponent
-The mouthparts, which due to the long nose is necessary for beetlewings so that from the mouth as little food as possible. The long tongue also helps (but it is less than the silkwing's tongue)
-2 pair of wings: the first is twice as short as the second, it performs the role of elytra
-The second pair of wings can fold and hide under the first
-Double thorn on the tail. The structure of the tail is similar to the tail of hivewings (the tail of the beetlewings is longer than that of the hivewings)
-Large thorns on the spine
-Semi-transparent beige blood
-Whites are also darkened, but not as much as in their descendants, hivewings
-Ears are pointed but not very long
-Omnivores
-Growth reaches 2.5-3.5 meters
*The design was based on bugs and some other insects
• Leafwings:
-Horizontal eye shape
-The presence of a modified ruffs (they are related to rainwings)
-Wings, webbed spines, ruffs and ears are leaf-shaped, and they can be very different in each individual (often their appearance resembles the plant after which they were named)
-Their scales do not necessarily have a green tint in all individuals
-Long, multi-ended horns that resemble tree branches. Many bigger than rainwings
-Paw structure almost identical to rainwings
-Sapwings and poisonwings try to distinguish themselves by applying paint on small fragments of scales, often making a small pattern from this (the first are painted in pale colors, the second, on the contrary, in colorful, mostly consisting of red, yellow and orange shades)
-In addition to this poisonwings can sharpen their webbed spines and horns, make them sharper
-Height reaches 3-4 meters
*The design was based on trees, their leaves and partly rainwings

Totally for unrelated reasons, what are some more facts about communication drones? Like uhhh specific anatomy ect?
Prepare to get spammed with information! 👀
Communication Drones Infopost
Communication Drones (calling them CDs for short here) are a sub-type of Worker Drones fitted with antenna and special storage systems meant to analyze, store and transcrypt incoming and outgoing signals between Outposts, (human) landing pods and machinery.
CDs can also communicate with each other & Workers around them in a certain range which allows them to be very effective in sending out orders en masse to other Drones.
(more below the cut for their anatomy, specialities and more!)
Most CDs have two to four antennas fixiated to their head which are directly connected to their auditory entrance (or well, 'ears' as we would call it in human terms) which makes their antennas vital for their work and general hearing. Damaged or removed antennas may result in a CD losing their ability to hear or at least reduce it greatly.
Depending on the size of the antennas it's easy to see what purpose the CD served - long antennas are usually paired with long-range signals which put the individuals at use to distribute orders, arrange communication between ships & pods on their way to other exoplanets (when humans were still around) and to manage incoming signals from other planets & stations/outposts.
Short antennas usually indicated a more localized position for the drone in question - mainly within a singular Outpost or in ships to work directly connected to the local machinery and computers, sending orders in smaller ranged areas and storing security data.
Most CDs have secondary enhancers which work similar to a short-range antenna allowing them to switch between long and short range at will (mainly used for CDs that had flexible working places between ground & flight).
Generally, the antennas also function as "mood indicator". They can rotate around themselves and change position dependant on a fixed motion range around the head - similar to how e.g animals use their ears to indicate mood, CDs quickly took these habits from dogs that were around Copper-9 and video material of animals and copied them. Not all CDs did or do that, but alot of them do. For example if an individual is excited/attentive, the antennas would stick right up. If they're overwhelmed/annoyed/angry they'd usually be lowered down or pressed against the sides of the head.
They were expected to be very attentive and pay close attention to details. Their inner storage was designed to hold literal months and even years of auditory data that they recieved which was usually extracted every 4-6 months via the ports on their back which connected directly to the storage. Without these "clear outs" most CDs experience involuntary deletion of audio files which is out of their control and might result in them forgetting things they've heard/analyzed before.
Other than those two features their anatomy is fairly similar to that of normal Workers, height etc. as well.
After the humans disappearance alot of CDs lost their use as there... well, were no orders to share and no signals to analyze. Some of them struggled with this loss of "useability", some were fairly happy about this.
Lost/destroyed antennas cannot be restored by themselves (well, unless a CD is a Solver User like Kira) and CDs usually do not take well to losing or damaging antennas. Enhancers aren't as sensitive, but still hurt. Touching them might also cause disruption in hearing for CDs, it would be like someone rang a bell next to a humans ear for them. :'D (no touchie!)
CDs are generally connected to ECHO in the MD: Echo story (outside of that this plot point doesn't matter, just mentioning it here haha). Since Kira was the first CD Echo tried to use as host it developed an interested in them since CDs are great tools to be used for mass-ordering hosts.
Alot of CDs were destroyed while the humans were still around, especially if their warranty expired or they became damaged, to prevent sensitive information (such as orders and analyzed data) from leaking or being stolen by enemy forces/entities.
CDs infected with a Solver usually had enhanced auditory strenghts, capable of sending much stronger signals regardless of their antenna's natural range of reach - and they could also "ping" other Users & Hosts which makes them easy tools of manipulation. Luckily the only known CD which acted as AS Host was Kira who was "patched", so it couldn't spread for now (excluding Echo :'D)

Octatrio being human for the first time
I wonder what did the Octatrio felt when they had human bodies for the first time?
Octopuses don't have any bones, so I wonder if Azul felt weird to have bony, non-flexible legs?
And what did they think when they saw their genitals as humans? I wonder if they mistaken it as an antenna?
Do they have many embarrassing stories during their potty training?
I was just curious after having this conversation with my friends.

Bug hybrid!Task force 141 x Human!reader
Bug hybrid AU LETS GOOOOO-
Warning: Bugs/insects/arachnids, sfw (I am a minor), fluff, bug shenanigans,
Let’s bug out y’all (I’m sorry please stay-)
Moth Hybrid Price:
-One of his moth antenna‘s are damaged leaving him unable to fly (He can glide though)
-Sometimes he eats your sweaters if you accidentally leave them in his office or quarters (He immediately apologizes repeatedly and tries to buy you a new one)
-During mating season he gets all fluffy like a moth (he’s gonna need help with shaving…)
-And yes, he can’t resist any form of light but only at night (Price is obsessed with Reader because their eyes shine bright from any light’s reflection)
Funfact: Moths are actually pollinators and feed off of nectar just like their cousin the butterfly.
Tarantula hybrid Gaz:
-Has the lower half of a Tarantula (Like a centaur but spider)
-Large Tarantula pinchers that can poke out of his mouth (Eating is messy for him. Poor Gaz)
-His bunk is completely covered in webs
-Has the urge to constantly make small webs to impress the reader
-During mating season he fluffs up like Price and also does a little mating dance (He’s only done it once on accident in front of the reader)
-Has Venom but it is weak when inflicted on humans (Some can have serious reactions depending)
-Likes to wrap the Reader in webs like a burrito (Blink twice if your endanger reader)
Funfact: Tarantulas can get severely injured if they fall from great heights (Be careful with your eight-legged friends)
(Centipedes honestly terrify me-)
Centipede Hybrid Ghost:
-Cury antennas (They twitch and move around)
-Lower half of a centipede (Like a centaur but centipede)
-His legs make little click sounds when he walks (Sends shivers down the spines of anyone who hears it)
-Disgusted of himself. Ever since the team’s transformation he’s honest to god disgusted and horrified of his appearance (Reader sees through that and helps him through it)
-Coils his lower half around the reader. Being the only remaining human of the task force he’s very protective of them like the others are.
-During mating season he gives off a foul Oder and makes webs to impress the Reader like Gaz does (They get very competitive with each other)
Funfact: Centipedes are not harmful to humans. In fact they help keep the pests away like cockroaches, moths, flies, silverfish and termites. They also do not make webs or nests indoors. (As much as they terrify me they do take care of the pests)
Praying Mantis Hybrid Soap:
-Has the mantis arms under his normal arms at his sides and cute antennas on his head. (And he has the Mantis tail. I believe it’s called a Metathorax?)
-Hunts like crazy (His urges constantly puts him in hunting mode)
-He’s always bringing back everything he hunts to the Reader (Makes him even happier if you eat what he gives you in front or him-or pretend to)
-Able to fly/glide for a short distance
-For mating season….uh….lets just say mantises are very horny
Funfact: Mantises can turn their heads a Full 180 Degrees. They have very flexible a joint between the head and prothorax that allows them to swivel their heads.
Bonus:
(Roach is Roach)
Cockroach Hybrid Roach:
-He has the Roach antennas, and roach arms/legs under his normal arms (He has the roach tail as well)
-Fucking indestructible. (Can literally survive radiation)
-Can literally eat anything (that’s from a living organism
-Cuddles. He’s clingy and always wants a cuddle from the reader after a long mission. (I honestly don’t blame him with the shit the task force goes through on a daily basis)
-Reader is very worried about Roach despite his indestructibility and always panics if he gets hurt during a mission. (He enjoys the attention)
Funfact: Cockroaches like to cuddle. Cockroaches like feeling something solid against their bodies. That’s why they hide in cracks and crevices or even your stacked towels and linens.

Wet Beast Wednesday: hermit crabs
There are some animals in this series that I relate with more than others. I kind of envy hermit crabs. I would love to have a hiding place I can carry around and retreat into to avoid social interaction. I'd keep some books and headphones in there. Hermit crabs are also an example of the internet's favorite part of evolutionary biology: carcinization, the tendency for many animals to evolve a crab-like body plan. Contrary to what some people seem to think, carcinization is something that happens in crustaceans only.
(Image: a hermit crab. It is a crustacean with a bright red exoskeleton with white spots and spikes. The head (with antennae and eyestalks), pincers, and two pairs of legs are emerging from a mostly white, conical snail shell. End ID)
Hermit crabs are over 200 species of decapod crustaceans of the clade Paguroidea. They are more closely related to squat lobsters, king crabs, and porcelain crabs than they are to true crabs. What sets hermit crabs apart from the other decapods is their asymmetrical bodies and soft abdomens. the soft abdomen is a major weak spot as it leaves the body vulnerable to predators. In order to protect themselves, hermit crabs have adapted to live inside of the shells of other animals, usually snail shells, but the shells of other molluscs have also been used. A few species have evolves out of the need for snail shells, such as the terrestrial coconut crab. King crabs (which are even more crablike than hermit crabs but still aren't true crabs) may also be a subset of hermit crabs that became even more carcinized and lost their soft abdomens. The relationship between hermit crabs and king crabs is an open question and a source of some pretty fierce debate. The abdomen is flexible and curls up, but is asymmetrical, usually bending to the right. This is so it can fit in the curling shell of a snail. At the tip of the abdomen are appendages called uropods that grab onto the inner column of the shell. The front part of the crab, including the head and legs, do have a protective exoskeleton. Of the 5 pairs of limbs, the rear two remain within the shell and hold onto it, the next two are used for walking, and the frontmost pair are adapted into powerful pincers. When a hermit crab retreats into its shell, it can use the pincers to block the entrance.
(Image: a mostly white hermit crab without a shell, seen from above. Normally hidden in the shell are two pairs of small legs and a long, soft abdomen that curves to the right. End ID)
The availability of shells is of vital importance to hermit crabs. They not only need local snail species to provide shells, they rely on the snails dying naturally or being killed by the type of predators that will leave the shell intact. A crushed shell is of no use. The availability of shells acts as an upper limit to the local hermit crab population. If there aren't enough shells to go around, those without them will die. The crabs don't just wear the shells, they remodel them. Through the secretion of chemicals and physically scraping at the shell's interior, the shell is hollowed out. This reduces the weight and increases the available shape in the shells. Remodeling is usually done by young hermit crabs. The shells last much longer than their inhabitants and the same shell can be used by generations of crabs. As the crabs grow, they will need to replace their shells. A shell that is too small stunts growth and can prevent the crab from retreating into it. A shell that is too large can be too heavy to move. Hermit crabs will fight each other over the best available shells. They will also attempt to steal good shells from other crabs. The attacking crab will grab onto the defender's shell and ram shells together. This continues until the attacker gives up or the defender leaves its shell. Hermit crabs have been known to form a chain of vacancy. When a crab finds a shell that is too big, it will wait for others to show up and do the same. Once one crab fits, it will abandon its former shell. The process will then repeat with the newly vacant shell until many crabs have traded. Shell fights and vacancy chains usually happen with the same species, but will occasionally occur between different species.
(Image: a pair of white and brown hermit crabs engaged in a shell fight. One hermit crab has climbed on top of the shell of the other one. End ID)
Hermit crabs are known to associate with other species of animal. Some species have a mutualistic relationship with anemones who grow on their shells. The anemone gets a place to live and transport while predators for the crab are warded of by the poisonous anemones. A genus of hydrozoans (tiny, anemone-like animals) called Hydractinia has evolves to live almost exclusively on hermit crab shells and are commonly called snail fur. On the other hand, barnacles or too many or too large anemones, can make the shell to heavy or too lopsided for crabs to use. Some species are known to tolerate the presence of small worms or amphipods who shelter in their shells.
(Image: a white and brown hermit crab in a large, white shell. On top of the shell is an anemone, which is a red, fleshy, flower-like animal. End ID)
While the vast majority of hermit crabs are marine species, there is a freshwater species (Clibanarius fonticola) and 17 land-dwelling species. These species spend their lives on land and only return to the water to mate and lay their eggs. All of the terrestrial species are members of the family Coenobitidae. 16 of those are in the genus Coenobita. The other one is Birgus latro, the coconut crab. While the other terrestrial species still wear shells, the coconut crab has a totally different lifestyle. This giant can get a legspan of 1 meter and weight of 4 kg (9 lbs), making it the largest terrestrial invertebrate. Their name comes from their habit of climbing palm trees to knock down coconuts, which they eat. While mostly herbivores, coconut crabs will hunt small animals and scavenge meat. They are also known for being curious and for stealing shiny objects, which gives them the nickname "robber crabs". Juvenile coconut crabs do wear snail shells, but as they grow, their abdomens harden, allowing them to live without shells as adults. Also, despite the meme, Amelia Earhart was probably not eaten by coconut crabs.
(Image: a coconut crab climbing a tree, with its head facing down. Its anatomy is similar to a hermit crab, but the abdomen is much shorter and has an exoskeleton. The crab is a dark brown color. End ID)
Hermit crabs of many species are kept in captivity as pets and in public zoos and aquariums. Terrestrial hermit crabs are more commonly kept as pets due to their easier care requirements. They are often promoted as easy pets that don't need much care, but misinformation leads to a high death rate and poor quality of life. Many species are marketed as living only for a few months when they can actually live over a decade with proper care. Hermit crabs are also notoriously difficult to breed in captivity, so they are usually harvest from the wild. This is leading to population crashes among popular pet species. Outside of the pet trade, there isn't a major fishery for the crabs outside of use as fish bait, though coconut crabs are edible and sometimes caught for food. Major threats to them include habitat loss, bycatch, and snail deaths resulting in fewer available shells. There has been a recent rise in wild hermit crabs using bits of trash such as glass bottles, plastic waste, and even light bulbs. These substitutes are less effective than shells and can injure or kill the crab as it tries to move in or out of them. Dead hermit crabs release a chemical signal that alerts other crabs to the presence of an available shell, which can result in the same piece of trash killing multiple hermit crabs. As of February 2024, 10 of the 16 non-coconut crab terrestrial species have been seen using waste instead of natural shells.
(Image: a brown hermit crab. Instead of a snail shell, it is wearing a plastic pipe elbow connector. End ID)
