Crop (anatomy)

A crop (sometimes called a croup or craw) is a thin-walled expanded portion of the alimentary canal used for storing food before digestion. It is found in many animals. It occurs in birds, some dinosaurs, and invertebrate animals such as gastropods (snails and slugs), earthworms,^[1] leeches,^[2] and insects.^[3]
