📖 Overview

Found in coastal, silty habitat on reefs amongst branching corals or with long-spined urchins, in depths to at least 15 m . Types were captured between 3-50 m on sand and coral bottom, but one paratype (USNM 112098) was taken at over 300 m, presumably in a trawl, on a bottom dominated by Globigerina .
