Larval and adult density of the porcellanid crab Petrolisthes armatus (Anomura: Porcellanidae) in an Amazon estuary, northern Brazil

a subtidal porcellanid crab, petrolisthes militaris (heller, 1862) (crustacea: decapoda: anomura), from the persian gulf, iran

the family porcellanidae is a group of crab-shaped anomurans and there are a series of studies on this group in the persian gulf. the first report of porcellanid crabs from the persian gulf was by heller (1861); who referred incidentally to two species of this group in a discussion of crustacea of the red sea.

A new species of porcelain crab, Petrolisthes tuerkayi n. sp. (Crustacea: Anomura: Porcellanidae), from the Persian Gulf.

A new species of porcellanid crab, Petrolisthes tuerkayi n. sp., is described from the Persian Gulf. The new species is closely related to P. rufescens Heller, 1861, but is easily distinguishable by having three or four large spines distally on the posterior margin of the carpus of chelipeds, whereas the posterior margin of the cheliped merus in P. rufescens is unarmed.

The Effect of Sex, Size and Habitat on the Incidence of Puncture Wounds in the Claws of the Porcelain Crab Petrolisthes Cinctipes (anomura: Porcellanidae)

Many porcelain crabs have an unusual claw (cheliped) form that is broad, flat and thin. This seemingly flimsy form suggests claws may be used more for display than for feeding or aggressive interactions. However, in the flat-topped porcelain crab Petrolisthes cinctipes, one of the most abundant intertidal crustaceans on the Pacific coast of North America, we observed a high proportion of indivi...
