On sexual dimorphism in the shrimp Palaemon pacificus (decapoda: palaemonidae) Collected from the red sea

Abstract

Palaemon pacificus is common in the Red Sea coast and the sexes are separate. Potential sexual dimorphism in 38 morphological parameters was investigated in a population of Palaemon pacificus collected from the Red Sea coast. The results indicated that 8 parameters show significant sex related differences while no significant differences were recorded in the rest of characters studied.
