Larval pirate perch look very similar to adults, except in the placement of the anus. Prolarvae and early postlarvae have 12-15 preanal and 13-196 postanal myomeres (Hogue, 1976). Once these fish reach 13 mm, the number of preanal myomeres will decrese as the anus begins migration toward the gular region (Hogue, 1976).
