rabbit

Science and Technology
  • A small mammal (family Leporidae) that has powerful hind legs that are adapted for jumping, and a peg-like incisor to either side of the upper incisors. Most species have large ears. Rabbits burrow and their young are born blind and helpless in the burrow; cottontails do not burrow but may use burrows dug by others. Rabbits are herbivores and practise caecotrophy, at night ingesting faecal pellets they take directly from the anus and storing them in the stomach to be mixed with food eaten during the following day, thus passing food through the gut twice. They will die if prevented from doing this. There are eight genera with 21 species native to North America, south-eastern Asia, Japan, and parts of Europe, South America, and Africa.
