More Info


Distribution

W of Geraldton to SW of Albany, Western Australia, the Tasman Sea, and the Lord Howe Rise, Wanganella Bank on the West Norfolk Ridge, and south to the Cascade Plateau. Elsewhere the species occurs in the Indo-West Pacific: South Africa, Mozambique, and New Zealand.
Inhabits continental slopes, seamounts, ridges and rises.

Colour

Bright red with scattered patches of darker pigment; lateral cirri bright red; inner part of mouth cavity and gill chamber including gill arches blackish.

Similar Species

The Red Coffinfish is most similar to Chaunax mulleus, having similar lateral line neuromast counts and squamation, with overlapping proportions. C. russatus differs from C. mulleus in having a very large illicial trough that is usually wider than the diameter of the eye pupil (vs. narrower), a uniformly deep red colour (vs. pinkish with red tips of the pectoral and pelvic fins) and a naked area in front of the illicial trough (vs. a narrow band of dermal spinules).

Etymology

The specific name is from the Latin russatus (= clothed in red), in reference to the uniform bright red colour of the body and fins.
