Crindelino (meaning "giant armored ones" in an ancient script) are New World placental cold-blooded mammals. Crindelinos live isolated lives in the hottest deserts for long lifespans currently estimated to be over two thousand years long.

Crindelinos are characterized by a leathery armor shell and long, sharp claws at the end of even longer arms. They have long legs, but are incredibly inflexible creatures, which impedes their mobility and speed. Newborn crindelinos typically measure between five and six feet tall, yet older crindelinos can grow to be over six hundred feet tall. Although they would be extremely capable predators, crindelinos frequently roll up into an armored ball whenever they are threatened by a predator, big or small.
