Manustrapdoora

***Manustrapdoora*** (meaning trapdoor hands in Latin) is a genus of the family Arpaktikoaltidae, and is in the tribe Arpaktikoaltini, and contains two subgenera, Kakomatia and Kalomatia, Kakomatia meaning bad eye in Greek, and Kalomatia meaning good eye in Greek. The most notable difference between the two subgenera is that Kakomatia have their eye stalks retracted by default, while Kalomatia have their eye stalks naturally out just like every other genus of Arpaktikoaltidae. The first species discovered by humans when they got to Hume III was Manustrapdoora manustrapdoora. Some people, including humans, Aununas, and the other four intelligent species on the planet, have an irrational fear of them, just like how people are scared of spiders, snakes, sharks, bats, and many other things that are completely harmless, this fear is called Megamanusophobia (meaning fear of big hands), this probably extend from the fact that some species have hands big enough to wrap around the entire head of a human.

## Evolution

This genus evolved from the genus Pterygiodaktylous, they evolved around 343mya and their point of origin is the rivers of South Primaterra. It started when a Pterygiodaktylous realized instead of just throwing some sand on top of it's self to only very lightly bury it's self, or instead of hiding between nooks and crannies between rocks, it decided to actually dig a burrow, this strategy worked a lot better in the fast-moving Rapids. Over time the hands became bigger so it can use them as a door, and over time the mouth became more moray eel-like rather than catfish-like, the reason for this is so it could hold on to pray better in the fast-moving Rapids. The species that this whole genus evolved from was Pterygiodaktylous tacheriatiskatapaktis, the first species of Manustrapdoora was Manustrapdoora tacheriatiskatapaktis. Kalomatia, the second subgenus didn't evolve until sometime between 334mya and 332mya. Only Kakomatia would go on to give rise to many more Genera, Families Orders, and even some Classes, but most of them are monospecific, and most of these classes are extinct today.

## Anatomy

The most notable difference between the two subgenera is that Kakomatia have their eye stalks retracted by default, while Kalomatia have their eye stalks naturally out just like every other genera of Arpaktikoaltidae. But other than that the anatomy for both is roughly the same.

### Head

Their head is where their brain is kept. It is also where the eyes, ears, mouth, and whisacles are kept. Their eyes are on stalks like a snail, and can be attracted and retracted just like a snail's eyes. They have ear stones that they used to both hear and maintain balance, they have a decent sense of hearing. Unlike other Genera in the family which have a mouth more like a catfish, this genus has a longer narrower mouth with Jagged sharp teeth protruding out, kind of resembles the moray eels mouth. Its teeth are Jagged and razor-sharp meant for killing and holding on to pray. It's tongue is mostly just use as a swallow assist but does have the receptors for the five tastes that we have but they are primitive versions, so they have a decent sense of taste. Because this species lived in fast-moving Rapids in order to reduce drag it had only medium length whisacles instead of the longer ones that other species and other Genera have, it's sense of smell is pretty decent not as good as it could be though. They had two gill slits on either side of the neck, these help them breathe.

### Body

#### Outsides

Their entire body is covered in scales. It has 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 only has three fingers no 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.

#### Insides

Their bones are made of calcium. They have a closed circulatory system and red blood. They have muscles and a central nervous system. They have two hearts, one of them being slightly reduced. They have both gills and lungs. Stomach, kidneys, intestines, and all that good stuff. They have a cloaca, and they reproduce by putting their cloacas together, they do not have a penis.

## Habitat

Their point of origin is in a fast-moving Rapid River in South Primaterra, but they have spread all throughout the shorelines of North and South Primaterra, and even the rivers of North Primaterra, and all over the ocean. When all the continents came together as one supercontinent they spread again and now they can be found all over the supercontinent.

## Diet

Considering their method of hunting they were probably 100% carnivorous and ate absolutely no plants. Their method of hunting is to sit and wait inside a burrow with their hands usually covering the opening, only jumping out when a prey items swims by, since plants don't often come by they probably would never catch a plant because unlike other Genera under this family these ones don't move a whole lot, they usually stay in their Burrows meaning they're not occasionally walking around and happening upon water plants to eat them. So yeah 100% carnivorous.

## Breeding

They reproduce by touching cloacas together and releasing gametes. First the male crawls out of his burrow to go find a mate. The male will distinguish if it's a female if it is bigger than him, and once it finds a mate, usually by smell, not sight, it will wait for a prey item to come by and when she grabs a hold of that prey item he slips into the hole and begins the mating process. The reason why he has to do it like this is because if he just tried to go right in she would eat him. After the mating process is done he better get out of there, eight times out of ten the males typically get eaten. After the female lays her eggs in her burrow she will then leave the burrow and build a new one. Once the eggs hatch some of them will eat each other the rest will swim out of the burrow and start their own lives.

## Adaptations

Their most notable adaptation and the one that all species in this genus have is their big webbed hands that they used to grab prey and act as a door to their burrow. Other adaptations vary from species to species, but one trade that seems to have independently evolved a handful of times is the ability to either slow down or stop all bodily functions in order to wait out times of hardship, similar to the naked mole rat or the water bear, this is how they survive The End Of Times Extinction Event.

## Threats

Their threats depends on the area they live in and what lives with them, anything bigger than it can eat it. There's also a few diseases that specifically Target them. And of course natural disasters.
