The Undulate Volute, Amoria undulata is a regular sight on any night dive at Rapid Bay.

They are strikingly beautiful and move quite swiftly over the sand hunting other molluscs. Volutes in general have gorgeous shell and body markings but what I really love about this one is how well they are matched. At a glance it is difficult to tell where the shell ends and the extended body begins.

I like photographing sand dwelling creatures such as this volute as the un-sensitive sandy bottom make it easier to get down really low.
