More Info


Distribution

In Australian waters, the Tuberculate Anglerfish is known from the Lizard Island area of the Great Barrier Reef, Queensland. Elsewhere, widespread in the tropical Indo-west-central Pacific, from the Red Sea, East and South Africa, eastwards to the Marshall Islands and Tonga, and south to New Caledonia and Australia in the Western Pacific.

Tuberculate Anglerfish inhabit coral reefs, from shallow reef flats to depths of 73 m, although most individuals have been reported from shallower depths. Individuals often shelter amongst branching corals.

Features

Meristic features: Dorsal fin spines/rays III, 12; Anal fin rays 7-8; Pectoral fin rays 9-12 (rarely 9, 10, or 12).

Illicium long, 1.5-2 times longer than second dorsal spine, tapering to a non-filamentous simple tentacle lacking a distinct esca; 2nd dorsal-fin spine cylindrical, not tapering, straight to slightly curved posteriorly; 3rd dorsal-fin spine only a rounded bulge; caudal peduncle absent.

Scales absent, skin thick and firm, covered with close-set bifurcated spinules.

Prehensile pectoral fins with an ‘elbow’ joint; posterior-most margin of soft dorsal and anal fins attached to body at base of outermost rays of caudal fin; all rays of caudal fin bifurcated.

Size

To 9 cm.

Colour

Body colour variable, typically cream or yellow (or slate grey) with dark-brown reticulations and marbling. Head with a whitish, scab-like pattern on face; anal and caudal fins with a conspicuous dark-brown band and marginal dark bands.

Feeding

Carnivore - ambush predator

Fisheries

Although of no interest to fisheries, Tuberculate Anglerfish are sometime collected for sale in the aquarium industry.

Conservation
