📖 Overview

This species forms colonies in muddy bottoms at depths of ca. 30 m off Amami-oshima island (its type locality). Photographic records from other localities were taken over sandy bottoms at depths of 10-12 m. Although sometimes exiting vertically more than 30 cm from their burrows, when approached, individuals immediately disappeared into the burrow with their head holding steadily at ca. several centimeters depth (visible from directly above the burrows). About 40 individuals were estimated for each colony, from a combination of underwater photographs and number of burrows .
