Porcellana sayana is a species of porcelain crab that lives in the western Atlantic Ocean, often as a commensal of hermit crabs. It is red with white spots, and has a characteristic bulge behind each claw.
Distribution
Porcellana sayana is found along the western coast of the Atlantic Ocean, from Cape Hatteras (United States) to Brazil, including the Gulf of Mexico and the Caribbean Sea.{{cite web |title=Porcellana sayana (Leach, 1820), spotted porcelain crab |work=A Picture Guide to Shelf Invertebrates from the Northern Gulf of Mexico |publisher=Gulf States Marine Fisheries Commission |author=Harriet Perry |author2=Kirsten Larsen |name-list-style=amp |date=June 4, 2004 |accessdate=February 6, 2012 |url=http://www.gsmfc.org/seamap/picture_guide/Crabs/porcellana.pdf }}
Description
Porcellana sayana is {{convert|13|mm}} long, and is red, with numerous whitish spots.{{cite book |author=Susan B. Rothschild |year=2004 |title=Beachcomber's Guide to Gulf Coast Marine Life: Texas, Louisiana, Mississippi, Alabama, and Florida |edition=3rd |publisher=Taylor Trade Publications |isbn=978-1-58979-061-2 |chapter=Sandy beaches |pages=21–38 |chapter-url=https://books.google.com/books?id=w0hWmtbRNwIC&pg=PA31}} It may be distinguished from other species by the form of the first pereiopod; the carpus (last segment before the claw) of that leg bears a lobe which projects forwards. It has a fringe of setae along the front of its claws, which it uses in filter feeding.
Ecology
Porcellana sayana lives in shallow water, at depths of up to {{convert|92|m}}, among rocks and oyster shells, or as a commensal of the hermit crabs Pagurus pollicaris and Petrochirus diogenes. Like another porcelain crab, Petrolisthes galathinus, Porcellana sayana is parasitised by the bopyrid isopod Aporobopyrus curtatus, which lives in the porcelain crab's gill chamber.{{cite book |author=Edward E.
