More Info


Distribution

Endemic to temperate waters of southern and western Australia from Kangaroo Island (South Australia) to off the Dampier Archipelago (Western Australia); bottom-dwelling in 145-183 m. Known only from a few specimens taken in trawls.

Features

Meristic features: Dorsal fin I + I + I, 15–16; Anal fin 8; Pectoral fin 9-11; Pelvic fin 5; Caudal fin 9.

Body short, deep, slightly compressed, caudal peduncle absent; head large, eyes small, mouth large, upturned, teeth numerous, short, recurved; gill opening a small pore below and behind the pectoral-fin base; second dorsal-fin spine above eye, very short, recurved, constricted at tip, covered with thick skin, but not connected to head by membrane; third dorsal-fin spine on nape, connected posteriorly along full length to body by thick membrane. Skin densely covered in tiny bifurcated spinules.

Illicium arising on snout tip, esca a single stout appendage entirely covered with fine hair-like filaments.

Soft dorsal fin base elongate, anal fin small, hind margin of dorsal and anal fins connected to the outermost caudal-fin rays; caudal fin rounded, rays branched; pectoral fins prominent, arm-like; pelvic fins jugular.

Size

To 19 cm.

Colour

Head and body variable in colour and scattered with dark, roughly circular spots or rings. Colour ranges from light tan, pale yellow, pinkish-brown, yellow-brown to brown, paler below; top of head and along part of back before soft dorsal-fin dark-brown, outer edge of all fins dark brown.

Feeding

Carnivore. Anglerfishes are ambush predators. The first dorsal spine is modified into a lure with a rod (the illicium) and bait (the esca), at the tip. The lure is moved to attract prey that are rapidly sucked into huge mouth.

Biology

The sexes are separate and fertilisation is external.

Fisheries

Of no interest to fisheries, aquaculture or the aquarium industry, although the species is may be taken as bycatch in commercial trawls.

Conservation

Not evaluated.

Etymology

The genus Allenichthys is named for Dr Gerald. R. Allen in recognition of his many contributions to tropical ichthyology.
