I hate this fact. Can we change it? Can we rewrite history and make bunny paws anatomically correct?

no

Here's a cool animal fact: Crocodilians only have claws on three fingers on each hand! Here's an image showing this in good detail. They share this trait with ceratopsian dinosaurs and lots of other ornithischians. It's pretty safe to say that only a very small amount of furs know this about them.
Also on the topic of crocodilians, alligators have penises that are always erect and work on a sort of "springloaded" system. They just fling out. It's really funny. Here's an article about it, if you're curious.

I include my self in that... about the fingers, I mean.

However, there is still phylogenetic distance between ornithischians (e.g. ceratopsians) and crocodrilians.

Crocodrilians, Ornithischians, Theropods (including birds) and many others, are Archosauria ... birds are Dinosaurs, but Crocodilians are not. In fact, in the Triassic the crocodrilians and relatives ( Pseudosuchia ) were disputing preeminence with dinosaurs, which was resolved by the Jurassic.

That's true! I only compared the two because of the interesting shared traits. It's possible that the shared ancestor of all archosaurs had this trait, because many early dinosaurs such as prosauropods had the non-clawed fingers too. As far as I can tell, only certain groups of archosaurs have the three clawed fingers and two non-clawed fingers, and in animals with fewer digits [such as T. rex and other tyrannosaurs] this trait also shows up as vestigial metacarpal bones, which makes a cool example of why and how this sort of thing ends up evolving multiple times along the evolutionary path.

Details such as hand and finger anatomy are often left out when it comes to anthro art, in favor of giving them more paw- or human-like hands, but it's cool to see anthro animals still keeping this unique trait when it comes up, even if rarely.

Boobs when you’re not pregnant/breastfeeding is uniquely human. Bit of a fact that I wish the general population knew, not just furries. This is in regards to games and movies with aliens in them, even those that try to be more realistic. I admit it’s a little weird that I find this slightly annoying

And milk glands in the form of modified skin glands in two rows on the ventral side of the torso is uniquely mammalian. Other animals also evolved milk, but the majority uses modified genital secretions (cockroaches, jumping spiders, pseudoscorpions) and birds produce it generally in their crops (pigeons, flamingoes). Milky aliens feeding their children would most likely be NSFW for a whole other reason than showing boobs.

Barring some very rare chromosomal mishaps, calico cats are female.

Female Heynas have a psudo penis. When they have sex it's like putting one penis inside another. They even give birth through it.

honestly depictions of aliens with a humanoid structure in general annoys me

like i get that depicting or even conceptualizing a truly alien creature is a tall order considering we only have this planet as a basis of what lifeforms even look like, but even depictions of sapient life more influenced other animals that aren't human is a rare sight (when was the last time you seen anything like the eosapien from wayne barlowe's expedition series or the qu from all tomorrows? )

Except for one species, female deer do not normally grow antlers. Only in rare occasions, such as when testosterone levels are elevated beyond the norm, do does develop antlers.

Reindeer AKA caribou are that one exception. Uncastrated adult males loose theirs by the time December rolls around, but gelded males and younger males keep theirs until December. Pregnant females keep theirs until late winter/spring to help them compete against other deer, which is why Santa's reindeer are sometimes portrayed as female.

In the water deer, one of the smallest deer species, antlers don't develop. Instead, the adults grow tusks, leading to the alternate name of vampire deer. Tusks are actually ancestral to deer, vanishing when they converted to growing antlers. The muntjac is a modern exception, developing both tusks and small antlers.

Musk deer also grow tusks instead of antlers, but they're not true deer, being more related to bovids like antelopes and goats.

Important to note it has to be pulled right in for penetration to happen.
Human dicks are actually pretty weird in the animal kingdom for not having much in the way of retraction muscles or fine-control over erection.

Speaking about cats.... do you know that sometimes you could tell from far, but REALLY FAR away, if a cat is male or female?

=).

Contrary to males, the females of mammals (at least) have different genetic composition in different parts of their bodies. That is because, they are "mosaics"... it has to do, that the "recipe" to make a human (or a cat) demands an X chromosome.... but ONLY ONE X chromosome. So in a female cell, one of the two in a functional diploid cell has to be de-activated, but during development, it is not always the same chromosome X which is de-activated in different parts of the early embryo.

Human penises are also unusual among mammals for lacking a bone (called a baculum) to help maintain erections. Furthermore, the human penis is very large compared to those of other great apes.

The bird equivalent of vocal cords is called a syrinx, and is located right where both lungs are joined at the base of the trachea. Some birds have independent control over each side, meaning they can produce two different notes at the same time. You can do a really poor imitation of this by humming while "blowing a raspberry" out of the corner of your closed mouth.

hippopotamus milk is pink

Rats and mice pretty much piss everywhere they go; they use this to mark their place and food.

"Fennec fox" as a name is technically redundant, as the word fennec comes from an arabic word meaning fox.

Raccoon dogs are more closely related to the vulpine family of foxes than the rest of the canid family.

Both fennecs and arctic foxes have thicker fur on their paws than other foxes(to deal with hot sand and insulate against cold respectively), usually obscuring their pawpads. Unlike rabbits they do have them, but both rabbits and these fox species tend to have incorrect paws in art.

Red foxes are thought to use the earth's magnetic field when aiming their pounces.

Canids, domestic cats, and european badgers have a scent gland on their tail called a violet gland, named after producing similar volatile terpenes to violets. Unlike the flower the quantity produced results in it smelling foul instead, this is one of the reasons why foxes especially smell so bad. On foxes it is visible as a dark patch on the upper surface of their tails, and it is also responsible for metabolizing hormones. The secretions are fluorescent in UV light.

Sharks do have more than one, uh, "penis" of a sorts, but they're external, not internal.
Beavers have a cloaca.

muntjac deer have scent glands on top of its head, and in its eye flaps...I think those are it's eye flaps... its a very weird race of deer

A late fun fact to your fun fact is they also aren't really penises. They're called "claspers"

cats, llamids, and camels are the only animals who walk by swinging the legs on one side of their bodies forward at once instead of alternately (ie. left front and left rear at the same time then right front and right rear instead of left front/right rear then right front/left rear).

I've seen this line before and I wonder where the fuck it came from because it's just very false. Most quadrupedal animals have a pacing gait. It's even the default gait for many of them- bears are really prominent and obvious examples.

clawstripe said:
The New Mexico whiptail is a species of lizard in which all members are female. There isn't a single male in the species. They reproduce by either hybridizing with two similar related species (a hybridization that can't produce a viable male embryo) or through parthenogenesis. When breeding season rolls around, they shift between two behaviors: a male mode in which one of the females goes through the motions of topping another but no actual penetration happens (because no equipment for it) and the regular female mode in which they bottom and their partner's motions trigger the release of ova which develop into clones of their mother.

HA!

kangaroos don't walk

Humans and dogs are really the only two predatory species for which maintaining eye contact is friendly. Even in wolves, dogs ancestors, staring into each others eyes is hostile. I suspect this is one of the main reasons cats are seen as so temperamental. Almost every time I've seen a cat slap someone it's after that someone has maintained eye contact with the cat for several seconds.

when you're out and about sometimes you'll see a monkey holding something long and thin and you might think it's playing with a rope but actually that's a dried-up baby monkey, some folks think this is because the momma monkey can't let go of her dead baby, but others reckon it's a tactic to get more food since nursing mamas get special treatment in monkey groups. Once other monkeys catch on that this works some of them even hurt their babies, after the baby dies, they guard the body until it's all dried up and then carry it around to score more grub.

If memory holds, this is also true of equids.

This is only true of horses. Zebra and donkey males have prominent nipples, one on each side of the sheath.

Given furries’ penchant for putting erogenous zones onto other erogenous zones I’m surprised this fact hasn’t really been picked up on.

Before I start, this isn't as serious of an answer, just mocking some euphemisms for human genitalia. Human males have two heads and human females have two sets of lips.

THIS.

It always annoys me to see paw pads on animals that don’t actually have them.
