The larval stages of the grooved shrimp Penaeus kerathurus (Forskal, 1775) were described and photos were taken
based on the materials hatched and reared in the laboratory. The larval development of P. kerathurus consists of 6 naupliar, 3
protozoeal, and 3 mysis stages before the first postlarva. Differences in the number of setae on 2nd antenna exopod and spine
formation on caudal furca were described for naupliar (N1-N6) stages of P. kerathurus and the chronological pattern was
compared with previous and relevant studies on other Penaeus species.
