The Pratas Island, the only island of Dongsha Atoll, has large coral reefs surrounded by deep sea situated near the holotype’s collection site. Public attention is called to the possible damage that frequent fishery activity in the area might be causing to the environment and natural resources of Dongsha Atoll (Ref. 129533).
