It is a common example of a living fossil as it belongs to a herd of fish that was thought to have died out over 65 million years ago. It can be found in the west of the Indian Ocean at depths of 150-700m along rocky slopes with submarine caverns pushed by strong oceanic currents. It has large and thick scalding with iridescent white spots, muscular paired fins and an unusually shaped tail. They are 1.5-1.8 m long and around 65-98 kg. The population of these fish are badly documented and estimates are difficult. The fish is endangered because of a restricted habitat range and chances of it being caught by man.
