Summary:
A reddish or silvery white bigeye with pink tinges, pinkish fins and distinctive deep purple to ink-black spots on the pelvic-fin membranes, including large spots on the membrane joining the abdomen. The species has relatively tall soft dorsal and anal fins, and filamentous tips on the tail.

More Info


Distribution

Shark Bay, Western Australia, to south of Cartier Island, Timor Sea, Western Australia, and off Innisfail to off Gladstone, Queensland. Elsewhere the species is widespread in the tropical Indo-west Pacific: Socotra, the Arabian/Persian Gulf and Gulf of Oman to India, east to the Indo-Malayan region, north to Taiwan and south to the Solomon Islands.
Adults are benthopelagic, inhabiting inshore and offshore rocky reefs and sometimes open bottom areas where they may form large schools at depths of 20-200 m. Larvae and early juvenile stages are pelagic, and presettlement stage individuals may form schools (Santana-Garcon et al. 2014).

Features

Dorsal fin X,11-13; Anal fin III,12-14; Lateral line, pored scales 51-67; Vertical scale rows (dorsal origin diagonally to anus) 40-50. 
Body moderately deep and elongate, laterally compressed anterior profile slightly asymetrical, extremity of protruding lower jaw usually slightly above level of midline of body; preopercular spine well developed at all sizes; dentary, vomer, palatines, and premaxillaries with small teeth. Caudal fin more or less truncate in smaller specimens, becoming very lunate in some (possibly males) but not all larger specimens.  

Colour

Pink to reddish, or silvery white with pink tinges, fins pinkish; pelvic fins with small dark purple to blackish spots on the fin membranes, including one or two larger spots on the membrane connecting the fin to the abdomen.

Feeding

Feeds on a other fishes and a range of benthic invertebrates, including crustaceans and molluscs.

Fisheries

A component of mixed-species fisheries in parts of its range.

Etymology

The specific name tayenus is presumably a latinization of Ta yan from Ta yen lap (=Large-eyed lap), the Chinese name for this fish as reported John Reeves, who painted the species while working as a tea inspector in China (Scharpf & Lazara 2020)
