Marine; reef-associated; non-migratory; depth range ? - 82 m (Ref. 37816), usually 15 - 40 m (Ref. 90102). Tropical; 32°N - 18°S
Length at first maturity / Size / Weight / Age
Maturity: Lm 7.9  range ? - ? cm
Max length : 17.0 cm TL male/unsexed; (Ref. 11441)
Indo-Pacific: Tanzania and South Africa to Hawaii and Tahiti, north to Japan, south to New Caledonia. Reported from the Arafura Sea (Ref. 9819). This name is used for at least four distinct species (Ref. 30915). International trade is monitored through a licensing system (CITES II, since 5.15.04) and a minimum size of 10 cm applies.
A rare inhabitant of shallow sheltered reefs, found among clumps of algae or in seagrass beds. Large adult pelagic and probably associated with drifting debris. Associated with sponges and sea-squirts (Ref. 30915, 58302). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Use in traditional Chinese medicine is increasing with the rise in patent medicines (Ref. 30915). Not common in the aquarium trade (Ref. 30915).
