Lagomorphs are preyed upon by many other animals, including wolves, dogs, coyotes, foxes, lynxes, bobcats, weasels, eagles, owls, hawks, and people. The body size of animals is considered to be determined mainly by evolutionary history and ecological conditions. This term is used to refer to the rabbit , hare and pika species collectively.
