Summary:
A spectacular scorpionfish relative with a very compressed body, no pelvic fins, and a long-based dorsal fin that arises on top of the head. This master of camouflage usually lives amongst sponges and varies in colour from a pale pinkish-orange to scarlet, brick red or bright orange - sometimes with indistinct spots.

More Info


Distribution

Endemic to the southern half of Australia, with a disjunct distribution from about Alexandra Headland, southern Queensland, to Potato Point, New South Wales, the Gulf St Vincent, South Australia, and from Cheynes Bay to Shark Bay, Western Australia. The species is not often seen in South Australia, possibly because it usually occurs in depths below 20 m.

Inhabits sponge gardens on coastal reefs and in estuaries at depths of 10-80 m - and is more active at night.

Features

Dorsal fin XXII-XXV, 14-17; Anal fin IX-XI, 4-7; Caudal fin 10; Pectoral fin 8; Lateral-line pores 14-27 (indistinct, minute).
Body elongate, extremely compressed, deep anteriorly (32-46% SL), tapering to very shallow caudal peduncle. Head large (30-35% SL); profile of snout vertical; eyes of small to moderate in size (10-16% HL), positioned high on head; mouth prominent (upper jaw length 27-36% HL), oblique; teeth minute, band in each jaw; each opercle with two low oblique ridges dorsally; head lacking sharp spines. 

Scales absent, skin mostly smooth; lateral line faint, angled from upper end of each gill opening to upper surface of caudal peduncle.

Segmented fin rays unbranched. Single high, long based dorsal fin originating in front of eyes, anterior spines except for short first spine long, those posteriorly somewhat shorter, of similar length to one another, continuous with caudal fin, connected by membrane to basal two thirds of uppermost caudal fin ray; anal fin of moderate length, low, posterior rays slightly longer; caudal fin rounded and somewhat elongate ventrally. Pectoral fins large, positioned low on body, extending beyond anus, with notches in posterior margin. Pelvic fins absent.

Colour

Colour extremely variable from brown with a network of thin red lines and white spots, overall reddish to orange with white blotches, or brownish with pink blotches.

Feeding

Carnivore - feeds mostly shrimps and other on crustaceans.

Biology

Little is known of the biology of this species. Red Indian Fish are well-camouflaged ambush predators and usually resemble sponges. Their sedentary life style enables bryozoa and algae to grow on their skin. While the growth of encrusting organisms may enhance their camouflage, they are known to shed their skin to rid themselves of such growths. 

Remarks

When out in the open, these well-camouflaged ambush predators usually resemble leaves swaying back and forth in the surge. Red Indian Fish 

Similar Species

The similar Whiskered Prowfish, Neopataecus waterhousii, has a distinctly narrow tail base and the dorsal fin is not connected to the uppermost caudal-fin ray.

Etymology

Pataecus is from the Greek "Pataeco". a dwarf-like Phoenician God, in reference to the similarity of the Red Indianfish to the images of Gods on the bows of ancient sailing vessels. The specific name fronto is from the Latin word for brow or fore part, in reference to the tall dorsal fin of this species.
