Rhabdus rectius

Rhabdus rectius, also known as a straight tusk shell, is a species of scaphopod, a small marine mollusc native to the coast of central California whose shell, like that of all the members of its order, resembles a tusk. Most members of the scaphopoda have shells that exhibit a noticeable and characteristic anterior curvature— the shell of R. rectius, however, is unusually straight, hence the Latin word "rectius" (literally, "straight") in its binomial designation.
