@spearxwind

Despite my fear of sharks and basically all aquatic life, still neat so tagging the other person I know who loves knowing and looking at Marine life.

Edit: did it seriously not post the actual link/pics lmao

Round 2 - Chordata - Chondrichthyes

(Sources - 1, 2, 3, 4)

Chondrichthyes is a class of jawed fish, commonly called “cartilaginous fish” due to their skeletons composed mainly of cartilage, making them distinct from all other vertebrates. They are comprised of the superorders Selachimorpha (“Sharks”), Batoidea (“Rays”), and Holocephalimorpha (“Chimaeras”).

Chondrichthyans breath through gills but lack opercula (gill coverings) and swim bladders. They have paired fins, paired nares (nostrils), and placoid (tooth-shaped) scales (except for electric rays, which have loose, soft skin). These placoid scales, also called dermal denticles, provide protection and streamlining, giving the animal’s skin a sandpaper-y feel. All chondrichthyans breathe through five to seven pairs of gills, depending on the species. As a general rule, pelagic species usually must keep swimming to keep oxygenated water moving through their gills, while demersal species can actively pump water in through their spiracles (a small hole or slit behind each eye) and out through their gills. Most larger, pelagic species no longer have spiracles. Chondrichthyans have many sensory organs to perceive the world around them. Their nostrils are attached to powerful olfactory organs. Around their face are a network of electroreceptors called Ampullae of Lorenzini, which allow them to sense electrical fields. Their lateral line has modified epithelial cells which sense motion, vibration, and pressure in the water around them. However, their sound-detecting apparatus has limited range and is typically more powerful at lower frequencies. Some species have electricity-producing organs which can be used for defense and predation. Chondrichthyans have a diverse array of shapes and sizes, ranging from the 10 cm (3.9 in) long, electric Finless Sleeper Ray (Temera hardwickii) to the over 10 m (33 ft) long Whale Shark (Rhincodon typus). All species are carnivores: some predatory, some ambush-hunters, and some filter-feeders. At least one species is omnivorous. Chondrichthyans have internal fertilization and most species give live birth, while some lay eggs. There is no parental care after birth, though some chondrichthyans do guard their eggs.

Chondrichthyans are considered to have evolved from Acanthodians, which appear from the Early Silurian. The first sharks began to evolve in the Devonian Period, though, while often claimed to be relatively unchanged, modern forms did not start appearing until the Early Jurassic.

Propaganda under the cut:

Mentioned briefly above, the Bonnethead Shark (Sphyrna tiburo), a small species of hammerhead, is the only shark known to be omnivorous. While it feeds on crustaceans, molluscs, and small fish, it also ingests large amounts of seagrass, which has been found to make up around 62% of gut content mass.

Also mentioned briefly above, Electric Rays (order Torpediniformes) are known for being capable of producing an electric discharge, ranging from 8 to 220 volts, depending on species, used to stun prey and for defense.

There are over 500 different species of sharks, and only a dozen could be considered dangerous to humans. That being said, of those 12, most do not seem to like the taste of human flesh, and bites are usually accidental or exploratory.

Many pelagic chondrichthyans occasionally breach, leaping out of the water. This can be done for hunting purposes, as a mating ritual, to shake off parasites, or even just for fun!

Today, all species of Sawfish (family Pristidae) are critically endangered. However, they were relatively common in the Cretaceous, where they were likely a common food source for Spinosaurus.

(Confusingly, Sawfish are a type of ray while Sawsharks (order Pristiophoriformes) are a type of shark. Sawsharks live in the deep sea and are rarely seen, while sawfish live in coastal and brackish waters.)

Kitefin Sharks (family Dalatiidae) have bioluminescent organs which glow blue in the dark

Chimaeras have a strange pair of teeth in their lower jaw which look like rodent incisors, giving them the common names “ratfish” or “rabbitfish.”

Great White Sharks (Carcharodon carcharias) are regularly hunted by orcas, and when one is confronted by an orca it will generally flee and not return to that area for up to a year.

Manta Rays (genus Mobula) are incredibly smart. They were the first “fish” in the world to pass the “mirror test” (ie show self-awareness by recognizing themselves in a mirror rather than seeing the reflected image as another manta ray). They also have highly-developed long-term memory, form friendships, and play with each other by blowing bubbles and breaching out of the water.

Just Us - Series List

Y/n is a multimillionaire. Wanda Maximoff is a divorced mum of two twin boys who is trying her best. What happens when their paths cross at a club and Y/n takes Wanda home for the night?

Warnings: This story is an 18+ read, Minors DNI, contains talks and description of Death, Accidents, Injury, Child Loss, Abuse (Physical and Emotional), Anxiety, Panic Attacks, Suggestive themes, Smut (Each Chapter With Themes Explained), Angst (Lots of It), And Some Fluff Thrown in because I felt bad. Top Reader, Bottom Wanda

Each chapter will come with their own warnings.

This is a story that I have put up on my Wattpad and my Ao3 and thought I would share it here for more of you wonderful people. I do hope you enjoy this read. There will be mistakes here and there and maybe some incorrect translations.

So this is an AU story with the MCU characters. So the ages and story lines with be changed and different from that in the movies. 

I will right some history for each character as the story progresses just so ages and other things make sense. 

All the Character's in this are played by their respective actors and certain aspects of the MCU have been added in. But once again its not going to be an alternative marvel story it is a completely different universe. 

I don't own any if the MCU characters.

[tinydefector]

I just want to give the babee a lil smooch and cuddle and a lil snack for being soo cute, plus Can we call new born oceanids guppy/guppies?

So my favourite part with Marine Centre due to how vast the Oceanides are they get quite a range of names for the offspring. It honestly depends on the person reporting on them.

But here are some if the other names they would get called: calf, Fry, fingering, hatchling. Are used alot for medical or reporting purposes.

But the nicknames that the employees of the centre or in general working with the very few baby Oceanides it ranges from: pup, Cub, guppy.

But also on that thought due to Bumblebee looking more like a reef fish very specifically Amphiprioninae (Clown anemone fish, Clown fish) he gets called little Fry alot. But becuase Optimus has a more whale/ Tylosaurus he gets called calf and Hatchling. But most times he gets put into the Pup category due to how much alot of the Oceanides are very similar to Sharks in some ways.

But here is some other information. Oceanides have life birth. I liked the idea of them having live births more than eggs and only have 1 to Max 3 pups/spawn. And that too also depends on the body type of the Oceanide.

This isn't cannon to the fic but I think it's fun to try and add them with species and genes.

Optimus, Mirage Oceanide: Balaenoptera mosasa

Megatron Oceanide: Selachimorpha ambysto

Ratchet, Ironhide Oceanide: Chondrichthyes

Rodimus, smokesceeen Oceanide: Chondrichthyes Mosasa

Starscream, Thundercracker and Skywarp. Windblade Oceanide: Istiophorus exocoetidae

Jazz, sunsteaker, Sidewipe Oceanide: Xiphias exocoetidae

But due to them being able to Interbreeding despite the diffences in genes they just get Classified As Oceanide nerdia

But hope this is a fun little peice to work with

(Did I have enough use my knowledge of identifying plants Species and genes to try and pull this out my ass yes, did I probably fuck up with the names who knows. They aren't plants so I have know idea)

Chomp

Hero found themselves in quite a precarious position, swinging upside down with their foot caught in a snare.

Now, this wasn’t exactly uncommon for them. Getting caught in a trap was nothing new. Such was the perilous life of a hero after all. What was unusual, though, was the pit of crystal clear water beneath them.

Oh, and the dozen or so sharks swimming around in it.

They were suspended over a pool fit for Olympic swimming. Hero was no marine biologist, but they were pretty sure those sleek grey fish weren’t dolphins.

Coarse rope dug into their ankle, but Hero found they didn’t mind too much. They had the core strength to be able to reach the knot but, unfortunately, untying it would probably send them plummeting into the water, and Hero wasn’t particularly up for such a literal swim with the fishes today.

Deciding to save their strength, Hero hung limp, tucking their shirt into their pants and leaving their arms to flop loosely with gravity.

Soon, the one responsible for their current predicament made themselves known from the ground.

“Welcome, Hero!” The villain’s voice boomed excitedly.

There was no catwalk, nothing covering the top of the tank. That left Villain to stand next to the glass at the bottom and having to yell up the dangling hero.

Before Hero could think to ask what they were doing here, Villain answered unprompted, “I wanted to show you my new collection!”

“Is this…legal?” Hero questioned, the words difficult to form with the blood rushing to their head.

“Absolutely not!” The villain exclaimed.

Right. That was probably the point.

“Are they…ok?”

Hero blinked hard, trying to stay present in the conversation.

“Who? Bruce, Anchor, Chum, Brooklyn, Barbara, Mark, Lori, Robert, Kevin, Lennie, Daymond, Nado, and Krill?

Their processing was gradually slowing down but those names seemed…oddly familiar.

“The…the sharks.”

Hero supposed they didn’t look too unhappy, chilling in their own space, not circling for an impending meal. Hero certainly couldn’t claim animal cruelty with the size of the aquarium. The oversized fish must be well fed to be able to coexist like this, which was…concerning for the hero, to say the least.

Their vision blurred as they watched a pointed fin breach the surface.

They realized belatedly that they were about to pass out.

“And they’re just fine with each other?”

“Oh, you see, that’s where my new invention comes in-“

The sound of Villain’s voice faded out as Hero’s consciousness slipped away.

…

They awoke to the sight of teeth flashing in front of them. They tried to scramble back before their brain could process the several-feet thick wall between them and the apex predator.

“You’ve been quite a rude guest.”

Hero turned to the source of the voice, finding Villain standing over them. The rope that had previously entrapped just one ankle now looped both feet together, as well as connecting both their wrists.

“I’m…sorry?” Hero spoke carefully.

That seemed like a reasonable answer, given their ultimate goal of not ending up as chum.

“You fainted before I could finish my monologue,” Villain pouted, crossing their arms and looking down at the Hero sitting against the wall of the tank.

“That’s…uh, my bad,” Hero answered, preoccupied with wondering when the sharks’ last meal was.

“Please, continue.”

Villain crouched down, looking intently into the Hero’s eyes as they started to explain.

“First, you have to understand the aggression patterns of bull sharks vs those of great whites and tigers…”

And that’s how Hero learned way more about Selachimorpha than they ever wished to know.

Blackmouth Catshark (Galeus melastomus)

[dasturdlydangerousduck]

Ocean Log Day 6:

What a harrowing turn of events!! I came face to face with an actual Selachimorpha!! It was quite scary! All the times that I have mimicked this fascinating creature has finally come up to me... Oh, and that very embarassing looking emission was from the methane gas from the seafloor I promise you.

2024 Fic Round Up

My beloved @puckdoll tagged me in the fic round up! Unfortunately, I have over 115 works posted from this year alone on my main Ao3 account so I didn’t want to spam the dashboard.

HOWEVER I have chosen my favourites from each month + commentary. (Also let me know if you want to see my beautiful Ao3 spreadsheet)

January:

something tragic about us Saw (Movies) Adam Faulkner-Stanheight/Lawrence Gordon/Mark Hoffman

Started off the year with a gross threesome! I think Adam should suffer <3 This originally started differently with more about Adam walking home, but it was so BORING that I cut the entire thing. The first lines I came up with were Adam not wanting to roll onto his stomach because he was overstimulated, which set up my theme of the fic nicely :)

February:

Hey blondie Saw (Movies) Adam Faulkner-Stanheight/Lawrence Gordon

The fic I’d been wanting to write for MONTHS!! I think young Cary Elwes is gorgeous jailbait, and I couldn’t think of a good enough set-up until the Bulletproof exchange. I miss the era of fandom where people shipped actors as different characters, so it was lovely to picture older Adam ruining young Lawrence’s throat.

March:

kingdom through the wilderness Saw (Movies) Adam Faulkner-Stanheight/Jigsaw Apprentices

A special birthday omegaverse gangbang fic for Monty! Sometimes you just need to destroy Adam and get him all covered in cum as a treat for your bestie. I couldn’t figure out if I wanted Logan to appear in this or not, so he’s technically there, but hidden. Also had to slip in some breeding kink because hnng hot. 

April:

psalm 3 The Locked Tomb Gideon Nav/Harrowhark Nonagesimus

First non Saw fic and shortest of them all! I really love this drabble, and I’m annoyed it didn’t get enough love. I think the kiss description is good, and the contrast between Alecto’s POV and what Gideon is saying works well. 

May:

nothing good starts in a getaway car The Passenger  Benson/Randolph "Randy" Bradley

My first Passenger fic, and it’s a 4k fic about Randy getting railed! I never disappoint. Honestly loved writing this, and I hadn’t realised that other people enjoyed it as well until I realised it was being recced. I tried really hard to “get” Benson’s voice as I was writing this, I found it hard to describe his sing-song way of speaking. I also got really into blowjobs where the cock fucks the side of the mouth so included that in there >:)

June:

call me pretty thing Saw (Movies) Adam Faulkner-Stanheight/Alison Gordon/Lawrence Gordon

I LOVE this stupid femslash poly au that I’ve come up with, and I could write thousands of words based in this universe. I think Alison works perfectly as a mean domme, and I know she and Lauren are the hottest dyke couple in Saw City. I enjoy reading BDSM aus (thanks hockey fandom) but I don’t know how good I am at writing them. 

July:

yield the need A Castle for Christmas (Movie 2021) Myles/Thomas (A Castle for Christmas)

I forced Becky to watch A Castle for Christmas last year, and unfortunately, she thinks it’s the best movie ever made. We came up with a very in-depth backstory for Thomas and Myles’ relationship that hits all our buttons (Scotland, repressed homosexuality, teenagers rutting all over the place) so I had to write a fic for the Battleship Exchange. I loveeee writing older men tackling their sexuality and getting their rocks off.

August:

cherry tree Delicious in Dungeon Senshi/Chilchuck Tims

The fact that there is SO LITTLE Senshi/Chilchuck fic is a crime. I really wanted to hit the fisting tags for Battleship Exchange, along with hitting my own size kink desires. This fic literally spilled out of me - I honestly think I wrote it in about an hour in a fugue state. I also never write about men’s balls and wanted to include it in this fic because I know what the Senshi fuckers want >:)

September:

Selachimorpha Jaws (Movies) Martin Brody/Matt Hooper

Another fic where I had a VIBE in my head that I was really trying to pin down - Hooper sweating in the bar and catching sight of Brody and realising he’s in love. I also think the title works really well, Selachimorpha is the scientific name for sharks and I remember my beloved poetry professor telling me to always use latin/scientific words in my work. Shout out to *REDACTED*, sorry for not replying to your facebook messages.

October: 

scent of you Original Work Stepmother with a huge dick/Teen stepdaughter she impregnates

I only posted two fics in October (damn my full time job!) but I did love this horny Original Work for the RelationShipping exchange. My recip was very into mind control, so this was my first foray into that kink and I think it worked well >:) This fic also got me blocked by some mutuals because they didn’t realise I was a freak!

November:

a softer jigsaw trap Saw (Movies) Lawrence Gordon/John "Jigsaw" Kramer

I wrote SO MUCH for Fic In A Box, but I just had to choose these softer world inspired panels. I feel like I worked the hardest on these - I practised first with some Hoffman panels, did a lot of editing of screenshots to create new scenes between Lawrence and Jill, and dusted off my old Photoshop skills! It was also SO MUCH FUN, I loved picking the quotes for the Lawrence/John relationship.

December:

No official December fic yet! I’ve written fic for several exchanges that will hopefully go live this month, so we’ll have to wait and see. ✌️

[muttism7]

Guys give me shark types/breeds to study and post about!!!

I’m starting with my first favorite, the Greenland Shark!!

The greenland shark is also known as the gurry shark or grey shark!! Its scientific name is the “Somniosus Mircocehphalus. It is a large shark in the “sleeper shark” family!!

Uhm uhm. Its full scientific categories are

Domain

Kingdom

Animilia

Phylum

Chordata

Class

Chondrichthyes

Subclass

Elasmobranchii

Subdivision

Selachimorpha

Somniosus

Species

S. Microcephalus

They have the longest known lifespan of all of the vertebrae species!! Said lifespan is estimated to be around 250 - 500 YEARS!!!!! Like holy shit.

Its meat is actually toxic, however when its treated to reduce the toxins its actually eaten as a delicacy in iceland!!

Historically, it has been hunted mostly for its liver oil, that was until synthetic oil was developed. Now it is mostly hunted for its meat.

Some food they eat

Smaller sharks, Skates, Eels, Herring, Capelin, Arctic Char, Cod, Rosefish, Sculpins, Lumpfish, Wolffish, Flounder.

Small greenland sharks mostly eat squid!! ^^

Hmm…

Thats all for now!! :3
