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 animal’s 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 victim’s segmentations, where it will then inject a digestive enzyme into the prey’s 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 head’s 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.
