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.

Bird feet and legs The legs are attached to a strong assembly consisting of the pelvic girdle extensively fused with the uniform spinal bone (also specific to birds) called the "synsacrum", built from some of the fused bones. Birds are generally digitigrade animals (toe-walkers), which affects the structure of their leg skeleton. They use only their hindlimbs to walk (bipedalism). Their forelimbs evolved to become wings. Most bones of the avian foot (excluding toes) are fused together or with other bones, having changed their function over time. Some lower bones of the foot are fused to form the tarsometatarsus – a third segment of
