This study aims to identify hemocyte type and assess some biological and biometric parameters such as differential count and hymocyte diameter in two crab species Grapsus albolineatus and Portunus segnis under light microscopy in the Persian Gulf covering Hormozgan province waters. Research samplings were carried out in Februrary 2011. According to cell size, presence or absence of cytoplasmic granules and nucleocytoplasmic ratio, three main groups of hemocyte have been recognized in both species: hyalinocyte, Small granulocyte (SGC) and large granulocyte (LGC). Our results showed that there is no significant relationship between gender and any kinds of the blood cell and also among total cells in the two species. The study showed that the size of blood cells in G. albolineatus was significantly smaller than the blue swimmer crab (P<0.05). In G. albolineatus semigranolocyte and in P. segnis hyalinocyte was the most predominant hemocyte, respectively 51.77% and 47.15%. Between the two species in terms of blood cell diameter significant difference existed and semigranolocyte and granulocyte dimeters were higher in P. segnis (P<0.05). However, hyalinocyte dimeter proved no significant discrepancy in this regard.
