Western Indian Ocean: Red Sea south to Mossel Bay, South Africa and east to India and Sri Lanka.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 35 - 45 cm
Max length : 75.0 cm TL male/unsexed; (Ref. 30573); common length : 30.0 cm TL male/unsexed; (Ref. 3507)
Found over rocky substrates of coastal waters. Juveniles stay in sheltered areas of estuaries (Ref. 5213). Large specimens caught from the shore only when seas are rough (Ref. 3198). Marketed fresh, whole or dried.
Also reported as a 'rudimentary hermaphrodite' or 'late gonochorist' where individuals posses an immature intersexual gonad but mature as either male or female fish with no eveidence of sexual reversal (Ref. 28504).
