The Cudovaste by Whachamacallit1 The Cudovaste by Whachamacallit1
The Cudovaste is a large terrestrial predator that inhabits the thick fungal forests of Southern Amazonia. Despite their size, they are ambush predators that use stealth to get near their prey. Their dark saturated hide makes it surprisingly difficult to spot them in their natural environment. Once near enough, the predator will launch its body towards the victim and restrain the animalís movements with its powerful forearms. When the animal has been restrained, the Cudovaste will use its huge, spider-like fangs to administer a precise bite to the victimís segmentations, where it will then inject a digestive enzyme into the preyís hide.
Once it dies from the poison, the Cudovaste feasts on the fresh kill. Unlike sabertooths of our world, Cudovastes can devour a large percentage of the carcass because of the lack of specialization in the true headís morphology. While it does have pseudoteeth designed for tearing flesh, the head has not been documented to have any use relating towards predation. They seem to be solely used for feeding.
Cudovastes mate once per year with one single mate. That being said, they do not mate monogamously. Several Cudovastes share parts of the same territory and will change mates each year, likely an adaptation to keep diversity within the population. They are able to recognize the individual via sound. While searching for a mate, the Cudovaste lets out a loud howl that sounds incredibly similar to a large train horn within our realm of hearing. The sound is likely to be more complex in inaudible levels, and presumably each call is different for each Cudovaste. The offspring that are produced from the full grown Cudovastes stay in a larval stage for about 2 Earth months, where they lack the ability to move. The only fully developed part of their bodies is the true head for consuming purposes. They are fed regurgitated meat by their parent, who leaves the larvae in a hidden den for protection. After reaching a certain mass, the larva become a pupa and gestates for 5 Earth months. After this, the fully developed-albeit small-Cudovaste breaks out of the cocoon and stays with the parent for an additional 8 Earth months, till it has learned more of the ropes and gears for survival. The parent will then proceed to drive its offspring out of the territory. These stages of development are similar with almost all arthrosaurs. There are variations of this technique, but they are all based off of this method.

Oh, and the color scheme was partially references off of Ameoboid's work. Check out her stuff here! [link]

Interesting. Now I want to see a picture of Jackson's Basin.

Well once I get my new computer, I can start labeling my map.

I really like these guys! Especially their reproductive process and early stages of life. Could you give a bit more information on how the reproductive organs work?

And thanks for the reference too! :D

You're welcome! But to give you a bit more insight in their reproductive organs, I'll have to go through a pretty discombobulated explanation. So Cudovastes-or really Arthrosaurs in general-are hermaphrodites that mate with another mate in order to fertilize. They do this by wrapping a prehensile everted penis with another one to start copulation. One side of the everted penis is covered with very fine and fairly rigid hairs that transport the "sperm" into the mate's body. The other side is a sort of receptor, where the "sperm" can travel relatively unharmed by the body's immune system. Once the sperm fertilizes the egg, the two halpoids becomes a zygote that is then transported down toward the base of the everted penis. There, the zygote quickly begins to develop and forms up a leathery shell. When the egg is being fabricated, the Arthrosaurs appear to have a large bulge growing from their back. After the shell is fully formed though, the bulge opens up and drops the egg to the ground and the wound from "laying" the egg heals up.

That's a very cool system, it's very different and alien. I like it!

It's actually partially based off of hermaphroditic snails, who use a similar organ to instigate mating. If you want to see how it looks, here it is [link]

Interesting! Slug reproduction is fascinating.
