More Info


Distribution

Recorded from off northeastern Tasmania, depth 825-1100 m. Elsewhere the species is circumglobal in tropical and temperate waters.

Features

Dorsal fin 5-7; Anal fin 5-7; Pectoral fin 17-18. 
Illicium relatively short, length less than 120% SL (71-112% SL in specimens greater than 12.5 cm SL), with no basal filaments; esca covered in minute spines, bearing distally-flattened papillae, and with an elongate, darkly pigmented distal prolongation attached to escal bulb; short, black filaments concentrated around tip of the prolongation; escal bulb with 2-3 unpigmented filaments; close-set pair of small appendages on posterior margin of illicium some distance below bulb. Dentary teeth in three longitudinal series, relatively long (longest 2.6-5.0% SL). Length of caudal-fin rays less than 45% SL.

Feeding

Stomach contents include bony fishes and squid. The large teeth positioned outside the jaws enable this species to seize large prey.

Biology

Female and male gigantactinids are extremely sexually dimorphic. The dwarf males attach to the much larger females for a small period of time using pincer-like denticles - they do not permanently attach to females.

Similar Species

Differs from other Gigantactis species in having a relatively short illicium with no basal filaments, and in the morphology of the escal bulb.
