Abstract

Aspects of the habitat, size structure, and interactions of Voluta ebraea in the wild are provided here for the first time from underwater observations on coastal reefs at Cabo Branco, north-eastern Brazil. Seventeen different sized individuals of V. ebraea were observed, with the largest individual reaching 15 cm in shell length. This species inhabits mainly sandy bottoms, but is also found on rocks, on the sand among algae, and on gravel bottoms. Voluta ebraea feeds on the bivalve Trachycardium muricatum during the day, apparently detecting its prey through chemoreception. When hunting, V. ebraea moved forward towards T. muricatum and then raised the front edge of its muscular foot in an attempt to cover the bivalve and capture it. The data presented can be used in the implementation of conservation measures to help conserve natural populations of this endemic Brazilian gastropod.
