Summary:

A large well-camouflaged anglerfish that matches colour of sponges on which it lives. Individuals range from shades of yellow to brown, although white, pale yellow, tan, pink, red, green and black fish have been seen. Giant Anglerfish often have low, warty projections on their bodies, and the 'fishing lure' is a small tuft of flattened appendages.

More Info


Distribution

Known in Australian waters from the Houtman Abrolhos, Western Australia, around the tropical north to Sydney, New South Wales; also at Lord Howe Island.in the Tasman Sea. 

Elsewhere, the species is widespread in the tropical and sub-tropical Indo-Pacific and the Red Sea, from East and South Africa across the Indian Ocean to Hawaii and Central America. 

Giant Anglerfish are bottom-dwelling fishes (benthic) and are usually solitary, although may occur in pairs or trios. They often live on sponges in coastal, lagoon and offshore reefs and reef-slopes to 45 m.

Features

Dorsal fin I+I+I, 11-13 (rarely 11 or 12); Anal fin 8; Pectoral fin 10-11 (rarely 10); Pelvic fin I, 5.

Head and body sometimes partially or fully covered with low, rounded, wart-like swellings. 

Bony part of illicium about equal to length of second dorsal spine; second dorsal spine slightly tapered from base. Esca a small tuft of flattened appendages. 

Skin covered with close-set bifurcated spinules. Second dorsal-fin spine wider toward the tip, fin membrane thick, swollen and spinulose behind the spine, extending to base of third spine (width along attachment to spine usually as great as spine itself). Third dorsal-fin spine long and thick toward the end. Prehensile pectoral fins with an elbow-like joint.

Size

To 38 cm. One of the largest shallow-water anglerfishes.

Colour

Well-camouflaged and highly variable in colour, mostly in shades of yellow to brown, although white, pale yellow, tan, pink, red, green and black individuals have been seen.

In preservative: light beige or tan, green, brown, to black; illicium usually banded, eye with  0-15 short, darkly pigmented bars present radiating from eye. Lighter color phases  finely peppered with small dark spots or mottled with reddish-brown to yellow-brown patches of variable size; dark-brown to black circular spots sometimes present. Dark, more or less interconnected blotches giving appearance of narrow, irregular, vertical bars on fin. Darker colour phases often with tips of pectoral-fin rays white.

Feeding

Giant Anglerfish are ambush predators and rely on their excellent camouflage and  lure to attract prey. The first dorsal-fin spine is modified into a 'fishing rod (the illicium) tipped with a bait (the esca). The anglerfish remains motionless, moving its lure to attract fishes which are sucked into their large mouth at lightning speed.

Biology

Reproduction: Oviparous, sexes separate, fertilisation external. Eggs are produced in a gelatinous floating mass or 'raft' where they remain embedded until hatching. Larvae spend the first 1 or 2 months in the plankton before settling onto the reef.

Fisheries

Of no interest to fisheries, although Giant Anglerfish are sometimes collected for the aquarium trade.

Similar Species

Antennarius commerson can be distinguished from other species of the genus Antennarius by the following combination of characters: 8 anal-fin rays, 13 dorsal-fin rays (rarely 11 or 12) and 11 pectoral rays (rarely 10).

The second dorsal-fin spine also becomes wider toward the end and has a thick membrane that reaches almost to the spine tip and extends to the base of the dorsal-fin spine. The third dorsal-fin spine is also long and thick toward the end.

Etymology

Antennarius is from the Latin, antenna, meaning sensory organ, in reference to the modified first dorsal-fin spine. The species name commerson, is for Dr. Philibert Commerçon, a French naturalist.
