About this work

Ring-tailed cardinalfish (Ostorhinchus aureus), Ad Dimaniyat Islands, Oman. This small fish can reach a length of up to 14.5 centimetres (5.7 in) and is found in the Red Sea and off East Africa to Papua New Guinea, north to Japan, and south to Australia. Ostorhinchus aureus is one of a large group of nocturnal feeding fishes which has a black pigmented gut lining, apparently to hide the glow of bioluminescent prey from its own piscivores in turn. The eyes of O. aureus allow the transmission of ultraviolet light, which if it is proven to be able to see, could benefit its nocturnal foraging.
