İmail HakkI Uǧurtaş *, Murat Sevinç and Hikmet Sami Yıldırımhan (2003) In this study, erythrocyte size and morphology of the turtles, Emys orbicularis hellenica and Mauremys rivulata (Emydidae), and tortoises, Testudo hermanni hermanni, and T. graeca ibera (Testudinidae), living in Turkey were examined. Twenty-five specimens were used in the study. There were 6 of E. orbicularis hellenica, 5 of M. rivulata, 5 of T. h. hermanni, and 9 of T. graeca ibera. Erythrocyte morphology of these examined species was described using Wright’s technique. The sizes of erythrocytes and their nuclei were measured using an ocular micrometer at a magnification of 1600x. Results of this study were compared with previous work on the other reptile species. The largest and the widest erythrocytes were found in E. orbicularis hellenica and the smallest in T. graeca ibera. In terms of the studied species, the nuclear and erythrocyte sizes were found to be correlated (Testudinidae: r = 0.494, p < 0.001; Emydidae: r = 0.668, p < 0.001).

Key words: Testudinidae, Emydidae, Erythrocyte size, Erythrocyte morphology.
