This species is highly variable in test perforation, test shape, and amount of spongy material on the ventral side (Javaux 1999). This variability has been shown before only in cultured specimens (Arnold 1954).

This species is one of the characteristic species of mangrove assemblage in Bermuda, and also lives in Bermuda landlocked marine ponds fringed by mangroves. It occurs in mangroves of Florida-Bahamas and Columbia, and in Equator and Brazil (where it is called D. vadescens). It is reported in nearshore and lagoons of Florida-Bahamas and in brackish-water of Belize Shelf, probably coming from nearby mangrove areas.
