Arthropods in culture Arthropods in culture Culture consists of the social behaviour and norms in human societies transmitted through social learning. Arthropods play many roles in human culture, including as food, in art, in stories, and in mythology and religion. Many of these concern insects, which are important both economically and symbolically, from the work of honeybees to the scarabs of Ancient Egypt. Other arthropods with cultural significance include crustaceans such as crabs, lobsters, and crayfish, which are popular subjects in art, especially still lifes, and arachnids such as spiders and scorpions, whose venom has medical applications. The crab and the scorpion are
Sea spider insects or crustaceans. This is in dispute, however, as genetic evidence suggests they may be the sister group to all other living arthropods. Sea spiders have long legs in contrast to a small body size. The number of walking legs is usually eight (four pairs), but species with five and six pairs exist. Because of their small size and thin body and legs, no respiratory system is necessary, with gases moving by diffusion. A proboscis allows them to suck nutrients from soft-bodied invertebrates, and their digestive tract has diverticula extending into the legs. Certain Pycnogonids are so small that each
