The reason why some in the Devil May Cry fandom refer to the Switch ports as a travesty is because the dips in frames on handheld and the input lag (I'm assuming if docked and are using a Bluetooth controller) is a few frames then playing Devil May Cry, especially the third entry as how it's meant to be played i.e, like a fighting game, is very very bad when you're comboing till kingdom come and that's how it's meant to be played.

This just in, starfish are a radially symmetrical head with a stomach.

God I love echinoderms

If you told someone that there’s an entire group of animals that develop butt first as embryos are born bilateral but then grow a radially symmetrical head like a cancer in their side that then bursts out and lives as a completely separate organism from its birth form and moves via hydraulic systems…

They wouldn’t believe you. Yet one of the most beloved cartoon characters is one of them.

Vampiric vascular access PSA from your friendly neighbourhood fanfic writing medic: Where To Bite

For those of you who, like me, love to write/read this sad vampire (or indeed anyone who likes to write any vampire), there were just a couple of sexy little anatomy things that I wanted to highlight (purely for fun).

First: arteries vs veins - Arteries take blood at pressure generated by the left ventricle of the heart, hence the pulse, to tissues and organs. Veins are a low pressure system that take blood back to the heart (via all sorts of mechanisms like valves, suction pressure from inspiration, pressure gradients, etc). - The inherent not-quite-sexy risk to puncturing/bleeding from an artery (especially a big one) is the risk of clot formation and with that the risk that those clots travel (embolize) further down the artery. This can result in things like strokes or ischaemic limbs. - Major arteries have associated major veins running nearby them. - Because of pressure differences, arterial punctures can spurt blood out, whereas veins ooze. To drink from a vein you'd have to apply a little more suction, whereas drinking from an artery might be a bit more messy/squirty. - Sure, veins don't pulse in the way arteries do BUT the way that we find these big veins (without ultrasound) is via use of anatomical landmarks. Your fave vampire will likely know those landmarks. Durge will likely also know these landmarks...for other reasons.

The neck (the classic, and everyone's favourite) - One of the things we look for as part of a fluid status assessment/CVS exam is the JVP (jugular venous pressure), which reflects pressure changes in the right atrium. For this we look for the double waveform pulse on either side of the neck coming from the internal jugular vein. It's not really palpable in the way arterial pulses are, but it is visible in most people (especially at neck turned 45 degrees). - The internal jugular vein (IJV) AND the external jugular vein are the two chunky veins of the neck. The IJV in particular would be a good one to bite for the same reason it's often a favourite vein to use for central line insertion- it's large, superficial, and usually pretty straight in its course within the neck. - The carotids are the major arteries of the neck, sitting more in the midline and protected a bit by a muscle there (sternocleidomastoid).

The inner thigh (the smut writer's favourite) - Gods know that the femorals have been doing some heavy lifting in vampire smut fics. Given the fact that they are located on either side of the groin, any biting action there has the inference of a lot more physical intimacy. - Like the neck vessels, you have big arteries AND big veins in the femoral region too. You have the femoral arteries which lie again more in the centre (like the carotids), and you have the femoral veins which actually lie more medially (more towards the mid-line of the body, i.e further in on the groin). These then branch out. - For purposes of vampiric vascular access, the femoral veins would be just a bit easier to get into position wise, but they do run very close to the femoral arteries. Because of how anatomy and fat distribution works also worth mentioning that the femoral vein and artery also lie a little deeper, so would require a much deeper bite.

Peripheral pulses (for those little nibbles) - For a quick snack more peripherally, it's going to be much easier to chomp into a peripheral artery. Arteries have thicker, more muscular walls than veins and the more superficial veins get the flimsier they are (i.e would be bitches to try to puncture with fangs). - We often sample arterial blood by puncturing the radial arteries. The radial artery runs on the thumb side of the wrist, and is very easy to palpate! - One could also attempt the brachial arteries, which are just above the inside of either elbow. A little deeper, but still palpable. - For the more adventurous bloodsuckers, you could even go for the dorsalis pedis (top of the foot), or the posterior tibial (below and behind the innermost part of the ankle bone)! See below: Astarion sampling a little of that radial artery juice

Aftercare (for the bitten) - If you are biting an artery or big vein you will usually need to apply some pressure to stop the bleeding. - In terms of clotting, it depends on what magical properties you believe vampire spit has. If none, it generally takes a few minutes to stop bleeding with a bit of added pressure, but bigger puncture sites may take longer. - That said, all bleeding stops eventually in one way or another- just ask Durge. - Like always, after a big drink you may need to ask your cleric friend to help you out with a cheeky lesser restoration spell to stimulate erythropoeisis so you're not wandering around the Realms so deeply anaemic.

Happy biting, friends!

why do so many try to pin the blame of the radialization of american boys on the american educational system, it's a favorite scapegoat to ignore the actual harm that the internet and the manosphere has had on boys online. i guarantee a majority of american public school are not skipping over teaching the real tragedies of the holocaust or whatever else and causing boys to ideolize hitler or say bin laden had "good points" on tik tok. theres a deeper problem unrelated to fifth grade teachers actually.

[transit-fag]

Okay so like an S Bahn style system would be really good for the sprawling US cities with a dense core, an S-Bahn is basically where cities interline their transit in the city center to improve frequencies, the best American Example would be Philadelphia. While this does produce a radial system usually, it is beneficial in that it allows for significantly higher frequency in the downtown where - [I am interrupted by a large flock of birds attacking me]

Phylum Round 3

Annelida: Segmented Worms. This group includes earthworms, leeches, and many classes under the umbrella of “polychaete”. This diverse phylum encompasses deposit feeders (eating dirt), detritivores, scavengers, deadly ambush predators, filter feeders, parasites, herbivores, and more. They are broadly defined by their repeating body segments and parapodia, which are nubby appendages used for both movement and breathing. Some have curved jaws for catching prey or scraping detritus off of rocks, while others have wide, elaborate, brightly colored feather-like fans for filter feeding. While able to crawl freely, a majority of marine Annelids spend most of their time in self-built tubes or burrows. Among their many important functions, they play a key role in mixing soil/sediment, breaking down decaying organic matter, and providing a key food source to countless other animals.

Cnidaria: Jellyfish, anemones, corals, box jellies, and hydroids. They have a gelatinous body with radial symmetry, a decentralized nervous system, and tentacles surrounding a simple mouth. The defining feature of this phylum are their cnidocytes, or stinging cells. There are two different body plans of the Cnidaria; an immobile “polyp” attached to a surface, or a free-living “medusa” which can swim or drift in the water column. Many polyp Cnidarians, such as corals, live in colonies. Some corals build reefs which serve as habitat for other animals. Free-living medusa Cnidarians must return to the seafloor in a polyp-like stage as a part of their life cycle.

guys please save your breath because i won’t be reading ur long asks defending those mediocre white women. i’m in class rn studying the detection and characterization of planets outside our solar system using transit photometry and radial velocity 🪐✶

[finsarelit]

Jellyfish do not have a single centralized brain, but they do have nervous systems that are spread out radially throughout their bodies. These nervous systems are made up of about 1,000 processing neurons in adult jellyfish and can show some degree of neuronal condensation, which acts as an integrative nervous system. For example, box jellyfish have clusters of neurons associated with their eyes.

[theyshapedlikefriends]

Do you have any plush echinoderms??? They're my favorites but I don't ever seem to find any plushes of them! Their five point radial symmetry and water based vascular systems fascinate me

There are several of these from what I found (you can buy these via proxy service)

Wet Beast Wednesday: brittle stars

Some animals end up living in the shadows of others. Everyone knows about starfish, the famous branching echinoderms, and a lot of people know about brittle stars, but not as many people know that brittle stars aren't starfish, they're their own thing. But because they look similar, brittle stars are frequently mistaken for a type of starfish, rather than being recognized as their own animal. I aim to help these stars shine and be recognized as their own animal.

(Image ID: a green brittle star on a rock. It consists of a small, round central body with five long, slender arms arms emerging from it at equal distances from each other. Thea rams are lines on either side with small bristles. End ID)

Brittle stars are members of the class Ophiuroidea, which is closely related to Asteroidea, the true starfish. The name comes from the Greek "ophis", meaning "serpent", a reference to their long, skinny arms. Ophiuroidea is divided into two orders, Ophiurida (true brittle stars) and Euryalida (basket stars). As with all echinoderms, brittle stars are radially symmetrical, consisting of multiple body segments that radiate around a point, akin to the slices of a pizza. The majority of brittle star species have five segments, though a few have six or more. Similarly to starfish, brittle stars have their arms radiating out from a central disc. In brittle stars, all the organs are located in the disc and as long as the disc remains intact, the arms can be regrown. The mouth (which also functions as the anus) is located in the center of the disc and each body segment has a single jaw and tooth. Some starfish can regenerate into two animals if the disc is cut in half, but almost no brittle stars can survive being cut in half. That being said, some species can reproduce via fission, where the disc splits in half and each half regenerates into a fully-grown star. In brittle stars, the arms are narrower than the disc, making the disc much more visually distinct than in starfish, where it can be hard to tell where the disc ends and arm begins. The arms of a brittle star are slender and highly flexible. When in danger, a brittle star can sever one of its arms. This is usually done in response to predation, in hopes that a predator will opt to eat the arm while the star makes its escape. This is called autotomy and is the reason why the common name of these animals is brittle star. The arms are formed of multiple calcium carbonate plates called vertebral ossicles due to their resemblance to vertebrae. The ossicles are connected to each other by ball and socket joints, allowing for a great degree of flexibility. Most true brittle stars can flex their arms side to side, but not up and down, while basket stars can flex in all directions. In basket stars, the arms branch multiple times. Unlike starfish, brittle stars use their arms for locomotion. The arms move in a rowing motion to drag the star around. Some species can swim for short distances as well. By contrast, starfish (and urchins) move using tube feet. Tube feet are a common echinoderm trait and consist of small tubes with a sucker on one end that are inflated and moved with water pressure. Most echinoderms use their tube feet for movement and feeding. True brittle stars, by contrast, seem to use their tube feet primarily for sensory reception, though they are also used to help transport food to the mouth. Due to moving with their arms instead of tube feet, brittle stars are capable of much faster movement than starfish, though in short bursts. Like other echinoderms, brittle stars use a water vascular system, where water is drawn into the body and used to inflate and move the tube feet and as a substitute for blood. Brittle star reproduction is fairly standard for echinoderms. The males and females will release their gametes into the water column. Fertilized eggs develop into pluteus larvae, which swim using cilia. In the pluetus stage, echinoderms are bilaterally symmetrical. They become radially symmetrical during metamorphosis into the juvenile form.

(Image ID: a basket star on a rock. The central disc in brown and has a pair of arms emerging from each segment. Each arm branches repeatedly and those branches have their own branches, resulting in a vaguely bush-like appearance. End ID)

Brittle stars are eyeless, but can detect light. Most animals, and a lot of non-animals, have some ability to detect the presence or absence of light. True vision, the ability to form images, requires more complex systems than the might-sensing cells most animals have. More specifically, it requires an eye. Or at least that's what we thought until scientists found evidence that the brittle star Ophiomastix wendtii may be able to form imaged without an eye by using its whole body as one big eye (a sea urchin, Diadema africanum) also seems to have this ability). Brittle stars are covered with light-sensing structures called opsins that can detect the presence or absence of light, but vision-forming sight requires the ability to determine how much light is coming from what direction. O. wendtii uses chromatophores to alter its color and these packets of pigment-changing cells are arranged in such a way that they may provide that directionality. In tests, O. wendtii would travel to shelter when exposed to light with a greater than change likelihood while the closely-related O. pumila would move at random when exposed to light. O. pumila lacks the types of pigment that O. wendti has, which could prevent it from being able to form the directionality needed for vision-forming sight. This is reflected in the species' behavior. O. wendtii moved toward shelter when exposed while O. pumila prefers to bury itself. The possibility for vision to exist without eyes means that a lot of animals we previously thought of as blind may actually be able to see, though probably not as well as animals with eyes.

(Image ID: Ophiomastix wendtii, a red brittle star with larger bristles on its legs. Two legs are shorter and blunted, possibly having been damaged. End ID)

There are over 2,000 known species of brittle star that live all over the oceans, from shallow water to the deep sea. Most basket stars are seep-sea animals, though some shallow-water species are known. True brittle stars are mostly detritivores who crawl along sediment and eat bits of organic matter and tiny organisms. This behavior makes them seafloor engineers. Their feeding behavior stirs up the sediment, releasing nutrients and affecting the behavior of other species that rely on the sediment. Because of this, brittle stars are often highly important parts of their ecosystems. Some species follow different lifestyles. Some will target and eat sponges or coral polyps while others are active predators of small animals, filter feeders, or even omnivores that eat plant matter. Brittle stars often live in or on corals or sponges, which provide a source of protection. The relationship between star and coral or sponge may be symbiotic in some species, with the star eating parasites and pests that endanger its host. Basket stars are filter feeders that use their many branching arms to catch plankton. They need to live in places with a current as as such are often foudn on seamounts, where the underwater mountain directs the flow of water into currents. The star anchors itself to a rock, coral, or other surface and extends its arms into the current to make a net. The arms are lined with tiny hooks that catch plankton carried by the flowing water. Once caught, tube feet cover the plankton with mucus and transport it slowly to the mouth. The star will sometimes bring its arms to its mouth to speed up the process. When threatened, basket stars will bring in their legs and form a ball to protect the disc. Basket star arms are less muscular than those of true brittle stars and therefore they are not as fast. Basket stars generally get bigger than true brittle stars, with the largest species, Gorgonocephalus eucnemis, having a disc up to 14 cm (5.5 in) in diameter and an arm length of up to 70 cm (27.5 in).

(Image ID: a basket star in feeding posture. It is on a rock with some of its arms used to support it. The rest of the arms are extended into the water column, with every branch fully extended. It looks kind of like pale white ferns. End ID).

This basket star living in the St. Lucie County Aquarium in Ft. Pierce, Florida ripped itself in half shortly after being introduced to the exhibit. Esch half survived and regenerated into a full basket star. This is the only time this behavior has been seen in this species (Astrophytum muricatum). Of course, trying to rip yourself in half is a reasonable response to realizing you have to live in Florida.

STAR WARS EPISODE II: Attack of the Clones 00:01:58

[o-craven-canto]

Related to the convergence vs. contingency ask I got a while ago, here's a list of adaptations I'd expect to find on any planet with Earth-like surface conditions and complex (equivalent to Earth's post-Cambrian) life:

Cellular organization, eukaryote-like cells with separated compartments for genome and energy production; large organisms multicellular or at least multi-nucleate

Most energy in the biosphere ultimately from sunlight; most energy is produced in the shorter term by transferring electrons to a strong oxidiser, most likely oxygen

Sex-like recombination of genomes common; most large organisms have a unicellular stage in their lifecycle (e.g. a zygote) and reproduce sexually at least part of the time (and when they do, each individual has two genetic parents); some kind of sexual dimorphism is very common at any given time, at least at gamete level

Most biomass at any given time consists in photoautotrophs, i.e. organisms using sunlight to synthesize organic molecules from scratch; biomass on land is greater than biomass in water, unless land is rare or the colonization of land has not occurred a long time ago

Fractal structure and/or radial symmetry common among organisms that move little actively or not at all; phototrophs have leaf-like light collectors that overlap to form a dense canopy

Bilateral symmetry dominant among organisms that move actively (so, clear distinction between front and back, and between up and down, but not between left and right, especially in outer morphology); sense organs, mouth, and central nervous system concentrated at the front end

Multiple "tree-like" and "worm-like" clades; filter-feeding a very common strategy in water; everything that has to move fast in water is spindle-shaped

Nearly all mobile organisms have long-range chemical, mechanical, and electromagnetic senses (i.e. smell, hearing, and sight), with the respective organs arising independently many times; perception of electrical fields may be common in water but not in air; communication is overwhelmingly vocal and/or visual

Every large organism has some sort of skeletal support; a skeleton based on hydraulic pressure is common in small organisms that move slowly, and a jointed exoskeleton is probably common in small faster movers (hard shells built from carbonates or silica will be popular in water), but the vast majority of largest organisms (say, >1 kg) probably has an internal skeleton
