Gigantactis is a genus of deep-sea fish of the family Gigantactinidae. The species in this genus are poorly known and found in all oceans, at depths of 1,000–2,500 metres (3,300–8,200 ft). The most striking feature of these fish is extremely enlarged first filament of dorsal fin, called the illicium, with bioluminescent photophore at its end.
