Dissodactylus crinitichelis Moreira, 1901 and Leodia sexiesperforata (Leske, 1778): first record of this symbiosis in Brazil
Abstract
The crabs of the genus Dissodactylus are well known as ectosymbionts of irregular echinoids belonging to Clypeasteroida and Spatangoida. Dissodactylus crinitichelis is the only species of the genus reported in Brazil. The pea crab species has been already recorded associated with four species of echinoids in Brazilian waters. This paper reviews the known hosts for D. crinitichelis and registers for the first time the association between the pea crab and the sand dollar Leodia sexiesperforata increasing to five the number of known hosts for the crab.
