More Info


Recorded from the Australian territory of Christmas Island in the Indian Ocean (Schwarzhans & Nielsen 2011). This cryptic solitary species inhabits reefs in the Indo-west Pacific Ocean, from Christmas Island in the eastern Indian Ocean to Vanuatu and Samoa - living near the bottom in small caves and reef crevices.


Brotulids are live bearers, and a 3.8 cm SL female specimen was found to be gravid.


Ematops is from ichthy-emata (Greek) = fish-scale and ops (Greek) = face, eye; referring to the unique partial covering of the eye by head scales, which is not known in any other living ophidiiform fish. The species is named after John E. Randall.
