A large, bear-like animal native to Vulcan, sehlats typically possess six-inch fangs. Although sehlats can be ferocious in the wild, Vulcan families frequently domesticate them as pets. Spock had a pet sehlat, which died during his childhood (in 2237, or 8877 on the Vulcan calendar) after sustaining mortal injuries from the poisonous bite of a mountain lion-like desert predator known as a le-matya.
