Rabbits and hares have large front teeth, short tails, and large hind legs and feet adapted for running or jumping. In most, the length of the ears is considerably greater than the width. Although usage varies, the term rabbit generally refers to small, running animals, with relatively short ears and legs, which give birth to blind, naked young, while hare refers to larger, hopping forms, with longer ears and legs, whose young are born furred and open-eyed.
Rabbits are chiefly nocturnal, although they are sometimes seen in the daytime.
They have acute senses of smell and hearing. They feed on a wide variety of vegetation and are responsible in many areas for the stunted nature of the ground cover. Wild rabbits are frequently infected with tularemia , which is dangerous to humans. All domestic rabbits, including the so-called Belgian hare, belong to this species. Wild common rabbits are up to 16 in.
