Animal

An animal is any member of the kingdom Animalia, comprising multicellular organisms which differ from plants in certain typical characteristics, such as the capacity for voluntary locomotion, non-photosynthetic metabolism, pronounced response to stimuli, restricted growth and a fixed bodily structure.

Animals, or parts thereof, are often eaten as food. The study of Earth animals is known as zoology. In regular conversation the term refers to a non-sentient member of that kingdom – distinct from sentient lifeforms such as Clarence Bottlenose.
