Fterotodermia

**Fterotodermia** (feather skin in Greek), commonly referred to as **Dirds**, (due to the fact that the name Birbs was already overused), are a Endothermic class of Septempollicems. They evolved around 103.4mya, and their point of origin is South Primaterra. They evolved from a Dinoavesia ancestor, Waftasaurus (meaning gliding lizard), which evolves all six of its limbs into wings for gliding**,** and would eventually give rise to the Dirds. They are the Septempollicems' answer to Birds, but while most modern Dirds look similar to Birds they actually evolved slightly differently than Birds did.

## Evolution

While Birds started out with the setup that we're familiar with two wings and two legs, Dirds actually started out with six wings, but **Convergently** evolved the Earth Bird body plan, because it was the most successful. After the initial six wings many evolutionary experiments played out, some of which are still alive today, while others were evolutionary failures that went extinct, until finally landing on the bird body plan and it was the most successful and it's the most common type of Dird today. First was the six wings, it is unknown what order these evolved in so take this list with a grain of salt, next came the back set of wings evolving back into legs, so four wings and two legs, next came the middle and back set of wings evolving into legs, so two wings and four legs, next came the front set of wings evolving into legs, so two legs in the front and four wings on the back, this order went extinct, next came the front and middle set of wings evolving into legs, so four legs on the front and two wings on the back, this order also went extinct, next came evolving the front and back sets into legs, only leaving the middle as wings, next came evolving only the middle set into legs keeping the front and back as wings, this order actually got a couple of families, a few genera, and a handful of species and wasn't a one and done like the other extinct orders, but the order still went extinct, this next one happened a few times and there's even still some species that are like this today, becoming flightless and evolving all the wings into legs, some have lost a set or two and either walk on four legs, or two legs Like an Emu or an ostrich, some have even evolved either just the front or the front and middle pairs into arms, some have lost the middle pair and only have two arms and two legs, and some have even evolved mantis arms, luckily all the orders with flightless Dirds that have arms all went extinct. Next came one clade that got rid of the middle set of wings, and only had four wings, next came the front wings becoming legs, this order went extinct, some would evolve those four wings into legs and become flightless, and finally at long last the perfected body plan had evolved two Wings on the front and two legs on the back. After all that experimenting they finally landed on the perfect body plan.

On Earth, Birds used to have three fingered hands on the end of their wings, no bird alive today has these hands, but a lot of birds still show evidence that they used to have these, for example, some birds still have one singular finger sticking out of a part of their wing, if you ever pay attention while you're eating chicken you'll notice this on the chicken wing, sometimes this finger has a claw on the end, sometimes it doesn't, sometimes it's only there when the bird is a baby and falls off later, one species of bird actually uses it's claws to help it climb up trees whenever it falls out of its nest but then loses it once it gains the ability of flight. And some species of bird have completely lost this finger. The reason why birds used to have three fingered hands is because they evolved from three fingered handed Dinosaurs.

Since Dirds evolved from five fingered handed Dinoavesia, some of them nowadays still have two fingers, some of them have claws on their fingers their whole lives, others only have claws on them when they're young and they fall off when they get older, While others just don't have claws on them ever. Some of them only have one finger on their wings, sometimes with a claw on their wing for their whole life, other times the claw falls off when they get older, and some of them aren't born with a claw. And some Dirds don't have fingers on their wings.

Just like birds on Earth, most dirds have lost their penises. Evolutionary biologists have theorized that perhaps **bird penises** vanished because female **birds** preferred mates with smaller **penises**. In ducks and other species with phalluses, males frequently force females to copulate. But A.R.F. researchers think that reason is silly, and it's fairly obvious why they've lost them. The reason why most birds and dirds lost their penises is because they were too heavy and weighed them down during flight. I mean come on just use your brain.

It was once thought that birds on Earth, started with no beak, and then one of them evolved a beak, and that all modern Birds descended from that one beaked ancestor. But fossil evidence shows that all three of the major lineages of Birds **Convergently** evolved beaks independently of each other.

But Dirds started out with no beak, and then one clade evolved a beak and all modern Dirds evolved from that clade.

Also no Bird alive today has real teeth, there are some fossil birds that have both teeth and a beak. But unlike Birds, there some species of Dirds that still have both teeth and a beak. Fun fact, by a coincidence most of the species that still have a penis also still have teeth, and most of the species that still have teeth also still have a penis.

Dracosaurs used to rule the sky, just like Pterosaurs on Earth, but also just like Pterosaurs, when Dirds evolved they competed for the insectivorous and seedovore niches, eventually outcompeting them and stealing the niches from them, just like birds did the pterosaurs on Earth. After this the Dracosaurs we're stuck only having nieces like vultures and albatrosses, just like pterosaurs, and when the extinction event that wiped out the all the non-Fterotodermen Dinoavesia occurred they were wiped out with them. After the Dracosauria was gone, the Fterotoderms (Dirds) took off, and started traveling to the other continents, and meeting up with the other bird equivalents of all the other superclasses, and coexisting with them do to ecological niche partitioning. But a battle for the sky did occur, but it was ultimately a stalemate with them all deciding to just coexist through ecological niche partitioning.

## Bio-electricity

Levels of how much each class kept the electric ability,

Agrioderma 100%

Olisthirodermia 88%

Folidotodermia 75%

**Fterotodermia** 25%

Gounia 50%

Ypsilistasia 99%

Frynoskorpia 50%

Xenosynapsid unknown

Dinoavesia unknown

Dracosauria unknown.

The reason why most of them have lost their electric abilities is because of two reasons. One is maintaining those three big organs was costing them too much energy, flight takes a lot of energy so they couldn't have both. Two is the bigger those three organs were the more weight is added on making it harder to fly. So most either reduce the organ severely, or have completely gotten rid of them. 10% out of the 25% that keep the electric abilities are flightless dirds, 5% are Albinaelectriamatism dirds, another 5% are dirds that have reduced the ability down to the voltage level of static electricity, 2% have reduced it down to only being able to make their feathers stick up to make them look bigger to predators, another 2% have reduced it down to the level of those shocking gum prank toys, and finally 1% have reduced it down to the level of those shocking gum prank toys and have lost the ability to feel pain. About 8% of the flightless dirds have re-evolved the three organs back to normal size, while the other 2% still have them reduced.

Aposematism, and Albinaelectriamatism.

There are no aposematism dirds, and out of all classes under Septempollicema, Dirds are the least Albinaelectriamatic.

## Intelligence

On Earth, Birds exhibit a wide range of smart behaviors, including good memories, extensive communication, planning for the future, and remembering the past. Some birds can solve problems, and others have been observed playing: both activities that indicate more than just basic instinct.

Dirds also exhibit these behaviors, their average intelligence appears to be a little bit higher than the average bird intelligence, being somewhere around average placental mammal intelligence. Some species have reach near human-level intelligence, just like the Parrot and the crow on Earth. Some have figured out how to use money just like the crow, and some were put into an experiment similar to an experiment on Earth they did with chimpanzees, in this experiment they were given money, or an item that can be used as money, and they were given treats for a certain amount of the money, and just like the chimpanzees on Earth, some of them figured out they can gamble and even prostitute themselves for money. This experiment was done with over a hundred species, and about 37 of them figured out how to gamble and prostitute. One Behavior in Birds that is not been seen in Dirds is letting the oldest child bully the smaller children out of the nest, and leaving those children to die only taking care of the strongest, this behavior is seen in many unrelated bird species, but nowhere in Dirds, this is more reasons why we think Dirds are a bit smarter then Birds.

Some Dirds are smart enough to know how to talk just like parrots and a few other bird species on Earth, but unlike parrots which can only mimic our voices and not actually talk as far as We Know, some Dirds can actually talk, about 10% of Dirds can talk, and 3% of that 10% can actually understand what they are saying and actually talk.

## Anatomy

Dird anatomy, or the physiological structure of dirds' bodies, shows many unique adaptations, mostly aiding flight. Dirds have a light skeletal system and light but powerful musculature which, along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, permit the dird to fly.

Their head is where their brain is kept, their brains control the whole body. They have completely forgone the eye stalks, in most Dirds species their whisacles are extremely reduced to the point of almost non existent, they have external ears, their mouths are beaks, and some species have teeth, and they all have tongues.

They lost their eyestalks to reduce drag in flight. How good their eyesight is depends on the clade. Most D**irds** enjoy sharper **vision** than humans. **Dirds** can see certain light frequencies--including ultraviolet--that humans cannot see. In fact, many songdirds have feathers that reflect ultraviolet light. This light is used to communicate species, gender, and perhaps even social standing. No Dirds ever, had a parietal eye.

Most clades, for example the order **Dasseriformes,** the whisacles are so reduced that they don't even resemble whisacles anymore, more like two little nose hooks or spikes, the reason for this is because most Dirds smell through their operculums, so to reduce drag most of them reduced the whisacles, but some Dirds do retain the long whisacles for the purpose of tool uses, but the dirds with reduced whisacles can also use tools. Coincidentally most of the ones that still have long with the colds are also the ones that still have teeth and penises.

How good their sense of hearing is depends on the clade, but most have pretty good hearing. How good their sense of taste is depends on the clade, but most can't taste sour spicy or bitter things. All living Dirds have beaks, only a few species have teeth and out of all of those few species only one has flat teeth for eating plants the rest all have sharp teeth, that species is The Vegetarian Dird.

Like mention above, most of them have only four limbs instead of the usual six, but some of them do have six, typically two Wings on the front in two legs on the back. They have two operculums on their chest not only to breathe with but also to smell with. Almost all of them have reduced shortened tails that typically have tail feathers on them to help steer the Dird during flight or to active display structures, but some flightless dirds have lost their tails.

Their skin is covered in feather-like filaments called weathers, but most people just called them feathers. There are two types of weathers in Dirds, type 3 and type 4, type 3 is mostly found in flightless Dirds, while type 4 are mostly found in flying Dirds. Type 3 are very reminiscent the feathers of ostriches and emus on Earth being more hairzlike than feather-like. Type 4 resemble the flying feathers of Earth Birds, and are very useful for flight. Most Dird legs are covered in scales called wcales, but most people refer to them as scales, some Dird species have feathers growing in between the scales, just like some owls on Earth, unlike Earth Birds, some Dird species have lost the legs scales, and instead have replaced them with feathers.

Their internal organs are what you would expect heart, and lungs, and intestines all that good stuff. They have a closed circulatory system, a central nervous system, muscles, and red blood. Their bones are just like Earth Birds, hollow inside and very lightweight and they can be bent and twisted without breaking so easily. They also three organs that produces electricity, but some have reduced them or lost them.

On Earth, most Birds I have a gland that makes their feathers waterproof, To achieve that, aquatic **birds** coat their **feathers** with an oily substance known as preen oil, which is secreted from a **gland** on their rumps, above their tail **feathers**. This **gland**, known as the uropygial or preen **gland**, is present in nearly all **birds**, but its shape and size varies among species. One example of a bird that doesn't have this is the owl, whenever it rains the owl cannot fly.

Dirds don't have this gland meaning that most of them can't fly when it rains, a few of the Aquatic ones have evolved different ways to make their feathers waterproof.

They lay hard-shelled eggs just like birds on Earth also just like birds on Earth none of them give birth live.
