Lagomorpha

Rare card · No. 43607

There are 110 recent species of lagomorph, of which 109 species in twelve genera are extant, including ten genera of rabbits (42 species), one genus of hare (33 species), and one genus of pika (34 species); and in which one monospecific genus is recently extinct, that of the Sardinian pika. Lagomorphs are found on every continent in the world except Antarctica, with several regions being host to introduced populations of European rabbits and European hares. Lagomorphs are closely related to rodents. The two groups are differentiated by their teeth: rodents have two upper incisors, while lagomorphs have four. However, both lagomorphs and rodents must chew on foods with plenty of fiber to prevent these incisors from getting too long, as they will grow continuously...
