Cocco's lantern fish (Lobianchia gemellarii), also called Gemellar's lanternfish, is a species of lanternfish.

Males have a supracaudal gland, while females have an infracaudal luminous gland made of two heart-shaped scales,[8] flanked by smaller, triangular luminous scales.

[4] Cocco's lantern fish is bathypelagic and oceanodromous, living at depths of 25–800 m (82–2,625 ft) in non-polar seas worldwide.

[9] Cocco's lantern fish are oviparous, with planktonic eggs and larvae.

[9] The fish is named in honor of Italian geologist Carlo Gemellaro (1787–1866).
