Biology, distribution, and abundance of Allopetrolisthes punctatus (Guérin, 1835) (Decapoda, Anomura, Porcellanidae), in the rocky subtidal of Chome, central Chile

ABSTRACT The porcellanid crabs are diverse and abundant species inhabiting the intertidal and subtidal rocky substrate. One particular species is Allopetrolisthes punctatus, a medium-sized crab, poorly studied but strikingly abundant in some places of Chile. Near Chome (central Chile) large aggregat...
