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

[edit]

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.[2]

Description

[edit]

Porcellana sayana is 13 millimetres (0.51 in) long,[3] and is red, with numerous whitish spots.[4][2][5] 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.[2] It has a fringe of setae along the front of its claws, which it uses in filter feeding.[4]

Ecology

[edit]

Porcellana sayana lives in shallow water, at depths of up to 92 metres (302 ft), among rocks and oyster shells, or as a commensal of the hermit crabs Pagurus pollicaris and Petrochirus diogenes.[2] 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.[3]

Taxonomy

[edit]

Porcellana sayana was first described by William Elford Leach in 1820 as Pisidia sayana.[6] Its common names include "spotted porcelain crab"[2] and "Say's porcellanid".[5]
