Crop (anatomy) Crop (anatomy) A crop (sometimes also called a croup or a craw, or ingluvies) is a thin-walled expanded portion of the alimentary tract used for the storage of food prior to digestion. This anatomical structure is found in a wide variety of animals. It has been found in birds, and in invertebrate animals including gastropods (snails and slugs), earthworms, leeches, and insects. Cropping is used by bees to temporarily store nectar of flowers. When bees "suck" nectar, it is stored in their crops. In a bird's digestive system, the crop is an expanded, muscular pouch near the gullet or throat.
Food and drink prohibitions fairly recent addition to cultural food prohibitions is the meat and eggs of endangered species or animals that are otherwise protected by law or international treaty. Examples of such protected species include some species of whales, sea turtles, and migratory birds. Similarly, sustainable seafood advisory lists and certification discourage the consumption of certain seafoods due to unsustainable fishing. Organic certification prohibits certain synthetic chemical inputs during food production, or genetically modified organisms, irradiation, and the use of sewage sludge. The Fair Trade movement and certification discourage the consumption of food and other goods produced in exploitative working conditions. Other social
