Rabbits Ixdong to the mammalian order Lagomorpha.

They were originally classified with species such as rats, mice and hamsters as members of the order Rodentia because they all have chisel-shaped incisors which are open-rooted and continue to grow throughout the animal s life. However, rabbits have two pairs of upper incisors while rodents have only one pair, leading to the reclassification of rabbits (and the related Iiarcs and pikas) as Iagomorphs. Rabbits are burrowing herbivorous animals that live in large social groups. They are readily preyed upon by carnivores and much of their anatomy is adapted to sensing danger and making a rapid escape.
