SUMMARY
This species has been considered a circumtropical species and the most common intertidal sipunculan species in the Caribbean, inhabiting coral ruble or in crevices of calcareous rocks. The main characters that distinguish this species from its congeners are the reddish brown conical pre-anal papillae, some of which are posteriorly directed, the secondary rounded tooth on the edge (concave side) of the hook, and differences in the internal pattern of the hook visible when examined via transmitted light.
