Threaded Fig Shell
The family Ficidae consists of less than a dozen species of thin, somewhat fig shaped shells. Species in the genus Ficus are mainly found in tropical seas living on sand or mud intertidally or in shallow water, while the recently discovered genus Thalassocyon occurs at abyssal depths. Two tropical species occur uncommonly in NSW, and one species of Thalassocyon has recently been found on the continental slope.
