Biology

provided by Fishbase
Along the South African coast, it occurs on rocky bottoms at depths of 9 to at least 55 m; off the coast of Kenya it occurs below the major thermocline at 125 to 200; also known from deep waters off the Kerala coast of India at 250 to 300 m. Occurrence off the coasts of Kenya and India appears to be an example of 'tropical submergence' by which temperate species are able to live at tropical latitudes only in the cooler deep-water zone.
