Ctenizaoxuderce

***Ctenizaoxuderce*** (the name being a cross of the scientific names for trapdoor spider and mudskipper) is a genus of Arpaktikoaltidae, they are distinguished as their own

genus and not another Manustrapdoora by their ability to stay out of water for a longer period of time then Manustrapdoora. They fill up a similar ecological niche as the mudskippers on Earth but their hunting style is slightly different. The first species discovered by humans when they arrived to Hume III was *Ctenizaoxuderce ctenizaoxuderce*, at one point there is a species that ate young Aununa children, but it was hunted to extinction by tribal Aununa a few thousand years before Society was even started on Hume III, that species was *Ctenizaoxuderce otrogontonmoron*.

## Evolution

They evolved around 335mya, the first species being *Ctenizaoxuderce prima* and their point of origin is the beaches and the river basins of South Primaterra. They evolved from Manustrapdoora when a species known as *Manustrapdoora litoreincola* decided that there was less competition on the beach rather than in the water, so it decided to stay up there. Overtime they evolved the hunting strategy of the trapdoor spiders, but also developed some behaviors of the mudskipper. Some of them lost the The Moray eel-like mouth of the Manustrapdoora and would evolve back into a catfish-like one, while some kept the eel-like mouth, because of this they were originally divided into two subgenera, but upon further DNA inspection it was actually discovered that the ones that had a catfish-like mouth are not closely related enough to be a subgenus, the DNA test actually showed that all the ones with a catfish-like mouth are more closely related to individuals with a moray eel-like mouth then to each other, meaning they all evolved it convergently. It lost the eyestalks and its eyes became more like mudskipper eyes. This genus would give rise to many Species, Genera, Families, and Orders, and even a few monospecific Classes, which most of those are extinct now, but the most notable descendants of this genus are the class Dachtylopodia.

## Anatomy

### Head

Their head is where their brain is kept, and that brain helps them control their entire body. The head is also where their eyes are, where their ear stones are, where their whisacles are, and where their mouth is. Unlike the eyes of other genera under Arpaktikoaltidae, these eyes in this genus are not on stalks, instead they closely resemble mudskipper eyes, how good the eyesight is can vary from species to species but most of them generally have decent eyesight on land but kind of blurry in water. *Ctemizaoxuderce* can see almost 360 degrees around them and have excellent vision in air, but their vision in water is not so good. They have a sac filled with water beneath their eyes, known as a ”dermal cup”. They use their ear stones to both hear and maintain balance. Their whisacles do many things, such as sense of smell, luring pray, additional brains, and grasping appendages. Their mouth is what they use to breathe and eat, whenever they are in the water they use their gills to breathe, whenever they are on land they use their lungs to breathe. Their mouth is also full of razor-sharp teeth and a tongue. Unlike the mudskipper on Earth this wish has a tongue that it uses to help swallow food, unlike the mudskipper which doesn't have a tongue and instead it uses a special water suction ability to help it pick up food. It is believed to have all the same taste receptors as humans, but they are more primitive versions. They have two gill slits on either side of the neck, they use these to help with breathing.

### Body

#### External

Their body is covered head to tail in scales, the color of these scales can vary from species to species. They have no Dorsal fins or tail fins the only fins that it has are two sets of pectoral fins and one set of pelvic fins. At the end of the first pair of pectoral fins are giant five-fingered webbed hands, it uses these giant hands as a door to it's burrow, kind of like the trapdoor spider on Earth except instead of having the door be made of dirt it's made of hand, it also uses it's hands to grab a hold of prey when they get close. These fingers like the digits of tetrapods on Earth and the legs of the sea robin on Earth evolved from rays on the end of the fin, this genus has lost the rest of the rays, so it can no longer evolve more fingers, now it's stuck at five. At the end of the second pair of pectoral fins are a set of smaller hands with only four fingers, three normal fingers and one thumb, this set of hands is used to help it hold on to the inside of the burrow so nothing can pull it out. At the end of the pelvic fins is yet another set of small hands specifically to help it hold on inside the burrow, this hand also only has four fingers, three normal fingers, and a thumb. Their tale is prehensile with no tail fin on it and it is also used to help hold it inside the burrow, but whenever it's out of its burrow it can help maintain balance.

#### Internal

These are not particularly special internally, they are mostly the same as the rest of the Arpaktikoaltidae family, except for the fact that they have lost one of the two hearts, posessing only one. They do not have a penis, they reproduce by putting their cloacas together.

## Habitat

Before the continents collided, they could be found all over North and South Primaterra, both at river basins and at the shorelines of the oceans. After the continents collided they can now be found at the shorelines of every area of the supercontinent, and in just about every river, and lake, and excetera.

## Diet

That can vary from species to species, but most species are anywhere between 90 or 95% carnivorous and 5 or 10% herbivorous, while some species are 100% carnivorous. They hunt using a similar strategy to the trapdoor spider, they sit and wait for something to crawl or swim near, it depends on if the tide is in or out, when something gets too close it jumps and grabs with the giant hands.

## Breeding

Their mating ritual is a peculiar one. When it comes time to mate, a whole group of them will get together, and start doing a little dance with each other. Normally in any other animal, it be a male doing a mating dance and if the female doesn't like it she can move on to the next male, but here the females are doing it too, if the male and female aren't satisfied with each other's dances they move on to a another partner until they find when they are satisfied with and that's the one they mate with. Once they have chosen a breeding partner they will head back to the females burrow, and they will mate by touching cloacas together. After it is done both the male and female will watch over the eggs in a similar ritual to that of the mudskipper on Earth, the eggs will be laid in a air pocket in a tunnel because the surrounding water doesn't have oxygen, when it comes time for the babies to hatch the parents will gulp up the air allowing the little air pocket to shrink, then the water will take the babies, the babies will swim out of the burrow, and after that they're on their own.

## Adaptations

The most notable adaptation they have is there slightly bigger than usual lungs, these help them survive Out of Water a lot longer than other wish. This other adaptation has convergently evolved only three separate times, the ability to go into a type of stasis in order to wait out times of hardship, the three species that independently of all this are the ones that survived through The End Of Times Mass Extinction Event. Other species have their own various adaptations.

## Threats

Their threats can very depending on the species and where they live, most of the time they can catch a small Dird, but there are some Dird species that specifically hunt them, as well as the other flying creatures of Hume III. Anything that's too big for them to eat is considered a threat to them. Before the continents collided one of their biggest threats from The Aununas and the other intelligent species of the planet was overfishing and habitat loss, after the continents collided many species of this genus went extinct, but the ones that survived thrived, until humans showed up, and now once again their biggest threat is habitat loss.
