This very small, white wentletrap can grow to about half an inch and is a great home for small hermit crabs. Wentletraps are rarely found alive because they are offshore animals. Their shells are pointed with strong whorls that have distinct, widely space axial ribs. The aperture is round or oval with no canal and the aperture lip is heavy and strong. This univalve may feed on anemones and corals with their very long proboscis and there is some evidence that they may anesthetize their prey. Their egg string is unusual and resembles a string of beads.
