). The duration of the reproductive period of this species, however, is still unknown. The species dispersal is larval retention type: after larval period in the pelagic environment of the bay, megalopae return to terrestrial areas, by colonizing mats of red algae that grow on humid substrates. Early juveniles seek shelter among entangled thalli of these red algae, and after molting they migrate to soft muddy substrate (S.B. Martins, pers. comm.). Adults live on consolidated sandy banks of rivers flowing into Guaratuba Bay, forming large populations (
