Notes on the reproduction of the Transcaucasian Nose-horned Viper, Vipera ammodytes transcaucasiana Boulenger, 1913 (Ophidia: Viperidae) from the Işik Mountain (Çankiri, Turkey)

We report on the reproduction of the Transcaucasian Nose-horned Viper, Vipera ammodytes transcaucasiana, from a northern locality of Işik Mountain (near Yoncali village, Çerkeş, Çankiri province) in Turkey. During our fieldwork on 15 June 2015, we found a female in gestation period and brought it to the laboratory for our venom-milking studies. It was kept in a terrarium until it died on 17 November 2015. The specimen (snout to vent length= 533 mm, tail length= 62 mm) was dissected after the preservation procedure and the eight embryos found in it were measured: mean Length= 23.74 mm, mean Width= 13.78 mm, mean Weight= 1.87 g. © Biharean Biologist, Oradea, Romania, 2016.
