Desenvolvimento pós-embrionário de Pagurus brevidactylus (Stimpson, 1858) (Decapoda, Paguridae), em laboratório

Abstract

All the larval stages of the hermit crab Pagurus brevidactylus were studied in the laboratory, with special emphasis on external morphology and on the duration of each stage. The larvae were kept in individual containers, with water of 35‰ salinity and fed on nauplii of Artemia salina; room temperature was maintained at 24±1ºC. The post-embryonic development includes four stages of zoea and one of megalopa. All the larval stages are drawn and described in detail.
