Coelomocyte Studies of Three Species of Earthworm viz Polypheretima elongta, Perionyx sansibaricus and Dichogaster bolaui

Dr. Shankerappa S. Hatti

Abstract :

Morphological features, classification and numbers of coelomocytes were studied in Polypheretima elongata, Perionyx sansibaricus and Dichogaster bolaui. The coelomocytes are divided in to elocytes, granulocytes and amoebocytes. Granulocytes are divided in to two types, granulocytes GI and Granulocyte GII type. And amoebocytes are also divided in to two types, amooebocyte AI type and amoebocyte AII type. Apart from these coelomocytes, coelomic fluid contains numerous transitory cells at different stages of maturation. Coelomcytes present in the coelomic fluid and the blood of worms are same. The total number of coelomocytes per unit volume (ml) of the coelomic fluid was calculated. They differ in different species. Total number of coelomocytes per unit volume of coelomic fluid is 35.22±13.10, 43.73±14.70 and 40.13±03.80 in Polypheretima elongata, Perionyx sansibaricus and Dichogaster bolaui, respectively. Among the three species studied lowest number of coelomocytes are retrieved from largest species i.e., Polypheretima elongata.
