The elongate jewel squid (Histioteuthis reversa), so called because the photophores festooning its body make it appear bejewelled

A photophore is a light-emitting organ which appears as cultured.

The character of photophores is important in the identification of deep sea fishes. Photophores on fish are used mainly for attracting food or confusing predators. Photophores are found on some cephalopods, including Watasenia scintillans, the sparkling enope or firefly squid, which can create impressive light displays.
