Kiwa is a genus of marine decapods living at deep-sea hydrothermal vents and cold seeps. The animals are commonly referred to as "yeti lobsters" or "yeti crabs", after the mythical yeti. The genus is placed in its own family, Kiwaidae, in the superfamily Chirostyloidea. Macpherson et al. named the genus Kiwa after "the goddess of the shellfish in the Polynesian mythology", although Kiwa is a male guardian of the sea in Maori mythology.
