چکیده مقاله:

The Caspian Pond Turtle, Mauremys caspica, is a terrapin belonging to family Geoemydidae. 51 specimens (20 males, 31 females) were collected manually and net from different aquatic habitats in Golestan province. Skin.Morphometric characters were measured by digital caliper and the weights by electronic weight scales of this turtle is dark olive green in color and has rows of longitudinal yellow stripes on sides of head and neck.Their carapace is relatively flat, the bridge between the dorsal and ventral shells is bony, and ends of anal scutes are pointed. Fingers and toes have swimming membranes. Sexes were identified by location of vent on the tail.Sex ratios of males to females were nearly 2 to 3. The mean of maximum straight carapace length (SCL2) was 161.59 mm and 133.64 in males and females respectively. Ratios of SCL2 to maximum plastron length (PL2) were 1.08-1.22 (mean 1.149±0.037) in males and 1.01-1.15 (mean 1.087±0.035) in females, ratios of SCL2 to straight carapace width (SCW) were 1.30-1.50 (mean 1.39±0.063) in males and 1.20-1.45 (mean1.34±0.06) in females, ratios of SCL2 to carapace height (CH) were 0.023-3.15 (mean 2.72±0.65) in males and 2.14-8.78 (mean 3.209±1.49) in females, ratios of SCL2 to tail length (TL2) were 3.11-4.57 (mean 3.74±0.53) in males and 2.33-4.78 (mean 3.08±0.75) in females. Ratios of maximum straight length of femor-anal suture to interanal suture length were 3.202- 5.007 (mean 3.84± 0.45) in males and 2.64- 4.03 (mean 3.17 ±0.39) in females. There were not external parasites in studied specimens.
