Oryctolagus (/ˌɔːrɪkˈtɑːləɡəs/) is a genus of lagomorph that today contains the European rabbit and its descendant, the domestic rabbit, as well as several fossil species.
The generic name derives from Ancient Greek: ὀρυκτός (oryktos, “dug up”) and λαγώς (lagōs, “hare”).
Rabbits or bunnies are small mammals in the family Leporidae (which also includes the hares), which is in the order Lagomorpha (which also includes pikas). They are familiar throughout the world as a small herbivore, a prey animal, a domesticated form of livestock, and a pet, having a widespread effect on ecologies and cultures. The most widespread rabbit genera are Oryctolagus and Sylvilagus. The former, Oryctolagus, includes the European rabbit, Oryctolagus cuniculus, which is the ancestor of the hundreds of breeds of domestic rabbit and has been introduced on every continent except Antarctica. The latter, Sylvilagus, includes over 13 wild rabbit species, among them the cottontails and tapetis. Wild rabbits not included in Oryctolagus and Sylvilagus include several species of limited distribution, including the pygmy rabbit, volcano rabbit, and Sumatran striped rabbit.
Rabbits are a paraphyletic grouping, and do not constitute a clade, as hares (belonging to the genus Lepus) are nested within the Leporidae clade and are not described as rabbits. Although once considered rodents, lagomorphs diverged earlier and have a number of traits rodents lack, including two extra incisors. Similarities between rabbits and rodents were once attributed to convergent evolution, but studies in molecular biology have found a common ancestor between lagomorphs and rodents and place them in the clade Glires.
The European rabbit (Oryctolagus cuniculus) or coney is a species of rabbit native to the Iberian Peninsula (Spain, Portugal and Andorra) and southwestern France. It is the only living species in Oryctolagus, a genus of lagomorphs. The average adult European rabbit is smaller than the European hare, though size and weight vary with habitat and diet. Due to the European rabbit's history of domestication, selective breeding, and introduction to non-native habitats, wild and domesticated European rabbits across the world can vary widely in size, shape, and color.
European rabbits prefer grassland habitats and are herbivorous, mainly feeding on grasses and leaves, though they may supplement their diet with berries, tree bark, and field crops such as maize. They are prey to a variety of predators, including birds of prey, mustelids, cats, and canids. The European rabbit's main defense against predators is to run and hide, using vegetation and its own burrows for cover. It is well known for digging networks of burrows, called warrens, where it spends most of its time when not feeding. The European rabbit lives in social groups centered around territorial females. European rabbits in an established social group will rarely stray far from their warren, with female rabbits leaving the warren mainly to establish nests where they will raise their young. Unlike hares, rabbits are born blind and helpless, requiring maternal care until they leave the nest.
