生物學特性     字彙 (例如 epibenthic)

This species has been observed by divers at 10-27 m on sandy bottom. Another population is found around 30 m at the northern part of Amami-oshima Island. Its behavior of building large geometric circles on sandy bottoms, makes this species unique. Female length (Ref. 97258). The circular structure plays an important role in influencing female mate choice, it functions to gather fine sand particles for constructing nests in preparaton for spawning (Ref. 97259).
