Abstract

Barnacle of the genus Octolasmis are commonly called goose-neck barnacle and are frequently found in infesting corals, echinoderms, molluscs, horseshoe crabs, lobsters, isopods, sea- snakes, stomatopods. They are found in shallow waters attachedto the exoskeleton of the decapod crustacea, including crabs and few are found in depthgreater than 1000 meters. During a visit to Pazhaverkadu fishlanding center located near Pulicat Lake, Tiruvallur district, a single individual of Portunuspelagicus (Linnaeus, 1758) infested with Octolasmis sp. (Gray, 1825) was encountered. A further work on the effect of Octolasmis sp., and the correlationof its infestation with the thinning of muscle mass and histopathological changes mustbe studied.
