Sehlats are a species of non-sapient mammalianoid predators native to planet Vulcan. They are bear-like in appearance and have six inch long fangs similar to those of a saber-toothed tiger. Their bodies are covered in grayish brown fur. They walk on four paws with long claws on each toe and have a short tail similar to that of a lion.
Despite being originally native to the scarce rainforests of Vulcan's southern hemisphere, Sehlats are not suited for climbing and prefer to remain close to the ground. Smaller Sehlat breeds are commonly kept as pets by Vulcans. As a child, Mr. Spock had a pet Sehlat named I-Chaya.
