Clean and Unclean Animals

Deuteronomy and Leviticus state that any animal which chews the cud and has a cloven hoof is ritually clean, but animals that only chew the cud or only have cloven hooves are not. The texts identify four animals in particular as being unclean for this reason; the hare, hyrax, camel, and pig — although the camel ruminates and has two toes, and the hare and hyrax are coprophages rather than ruminants.

The Torah lists winged creatures which may not be consumed, mainly birds of prey, fish-eating water-birds, and bats. Leviticus and Deuteronomy state that anything residing in "the waters" (seas and rivers) is ritually clean only if it has both fins and scales.

Leviticus states that every creeping thing that crawls the earth is unclean (Hebrew: sheqets). However, a bug born inside a fruit may be eaten if it has never crawled on the ground. All "flying creeping things" are also considered ritually unclean, according to both Leviticus and Deuteronomy. Leviticus lists four exceptions, including locusts.
