	Parapinnixa Affinis ''Parapinnixa affinis'', the California Bay pea crab, is a species of pinnotherid crab endemic to Southern California. It is a small crab that lives commensally in the tube of a tube-dwelling worm. It was one of the first marine crustaceans to be included on the IUCN Red List in 1996. Description ''Parapinnixa affinis'' is similar to other pea crabs of the genus ''Parapinnixa'', especially '' P. nitida''. It differs from ''P. nitida'' in the proportions of its carapace, which is more than twice as wide as long in ''P. nitida'' but less than twice as wide as long in ''P. affinis''. The carapace is approximately wide, with a maximum of . The carapace is usually "light amber mottled with dark ochre", but 5% of crabs are albino. Distribution ''Parapinnixa affinis'' appears to be endemic to Southern California, having been recorded from San Pedro, Anaheim Landing, Newport Bay and San Diego. It was once recorded from Siberia, but this record is doubtful. Conservation and ecolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

He was a professor at the University of California, Berkeley (UC-Berkeley) for 27 years. He was a genetics pioneer and studied animal behavior, heredity, and evolution. Over the course of his career he migrated from studying animals to humans, taking the behaviors and traits learned in the former and looking for them in the later. Career After attending Chaffey College in Ontario, California, he obtained his Bachelor of Science (1893) and Master of Science (1895) from the UC-Berkeley. His biological research at Berkeley earned him a fellowship to the University of Chicago in 1895, where he received his Ph.D in 1897.

picture info	Crab Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) ( el, βραχύς , translit=brachys = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period. Description Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a pair of chelae (claws). Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span up to .
