AB  - The pattern of taxonomic relationships and morphological divergence of three three species of shrimp, <I>Penaeus semisulcatus</I>, <I>Metapenaeus monoceros</I> and <I>Melicertus</I> <I>kerathurus,</I> collected from Iskenderun Bay, were investigated. A multivariate ANOVA using morphometric characters revealed highly significant inter-sample variation for most of the characters. In discriminant function analysis, the first discriminant function accounted for 77% and the second accounted for 23% of the between-group variability, showing clear between-species differentiation. Examination of the contribution of each variable to the first two discriminant functions showed high contributions from measurements 1_2, 4_5, 11_12, 8_11, 8_9, 4_15 in the first function, and 7_12, 3_16, 3_4, 12_13, 8_12 in the second function, indicating that these characters are key characters in discriminating between these species.<I> </I>The UPGMA cluster analysis produced two main clustering; <I>Melicertus kerathurus</I> was closest taxa to <I>Penaeus semisulcatus</I> being the sister group to the <I>Metapenaeus monoceros</I> which was the most divergent in this group. In the correct assignment of individuals into their original sample, the proportion of correctly classified the <I>Metapenaeus monoceros</I> to their original group was highest (92%), showing a clear separation from the other species.
