Many people know that rabbits and hares are related, but pikas are also part of the family: these lesser-known cousins to rabbits and hares are grouped with them in the order Lagomorpha. These animals are not rodents, as is often assumed.
Rabbits and other members of the family are viewed from diverse perspectives, not only as treasured pets but also as vegetable garden pests. And despite the fact that rabbits multiply like rabbits, a number of species in the order are endangered. The lagomorph order is also larger than one might think: there are more than 90 species of rabbit, hare and pika, and new species are still being discovered.
