Human uses of animals include both practical uses, such as the production of food and clothing, and symbolic uses, such as in art, literature, mythology, and religion. All of these are elements of culture, broadly understood. Animals used in these ways include fish, crustaceans, insects, molluscs, mammals and birds.
Economically, animals provide meat, whether farmed or hunted, and until the arrival of mechanised transport, terrestrial mammals provided a large part of the power used for work and transport. Animals serve as models in biological research, such as in genetics, and in drug testing.
