               Scientific Name:
               Metapenaeus stebbingi
                                                                   Picture


               Key identifying features
                                                                  Brief history
               This shrimp reaches a maximum length of 11 cm in
               males and 14 cm in females. The smooth carapace is
               cream-coloured and speckled with rust-coloured
               spots. The antennae and margins of the tail fan are
               reddish. The rostrum has 7–10 teeth on the upper
               margin. The first and third pairs of walking legs have
               a basal spine. The longest segment of the fifth
               walking leg of males (the merus) bears a notch on
               the inner margin.


               Field identification signs and habitat            Reproduction
               This species inhabits sandy or sandy-mud bottoms  Females attain sexual maturity at a relatively small size
               down to 90 m in depth. Juveniles occur in shallow  (5.5–6.0 cm in length). The highest percentage of
               coastal waters and adults usually further offshore,  mature females occurs between May and June, but the
               buried in the substrate in daytime and foraging at  breeding season generally lasts from April to October.
