i changed the xelukarlanth a little
These giants live in caves and dark forests, with minimal light. Their hooked claws and the strange shape of their feet allows them to grip very rough surfaces, and their giant wings superior for flight. The Xelukarlanth use all of their claws to grip surfaces - yes, even their wingtips! It has 27 eyes, the eyes along its back or in its tail do not actually blink, they roll in the socket. Once a month, a group of Xelukarlanth fly out to hunt large animals in preparation for their mating season. Females are larger and more aggressive than males, and the females must fight over the males and impress them with strength and large quantities of food. It may not look like it has big teeth at first, but that's just because its gums are covering them. As soon as a Xelukarlanth begins a fight, it will bare its long, sharp fangs and screech - a display to intimidate and thus weaken the other. In a fight, it will bite, claw, stomp, ram, as well as flap their wings to launch their opponent away. The loser collapses and sometimes dies. Xelukarlanth eggs are soft and leathery. Hatchlings rely heavily on their mothers to learn how to hunt what's edible and avoid poisons.
TL/DR
A peaceful species of cave/forest wyvern with long catlike whiskers, 27 eyes, 10 nostrils, huge wings, and horns of any natural shape. Its feet are specifically evolved to grip rough surfaces. It does not breathe fire, water, or acid. It runs slowly, but it is very fast in the air. Teeth stay mostly in gums until needed.
