We studied beneficial difference of the skin of two snakes. Two snakes were chosen from two different habitats and two families: Colubridae (Natrix tessellata) and Viperidae (Cerastes vipera). The investigations were performed by light and electron microscopy. Histologically, the skin of the studied species show pronounced modifications that correlated with functional demands. The scales in Nat...

We describe the unusual case of erythrism in Eastern Grass Snake, Natrix natrix . This colour morph is very rare and has not been reported literature before. Despite having observed thousands N. field, we personally detected this only three individuals originating from Slovakia, Romania, mainland Greece, while photos a fourth individual Greek island were provided to us. In addition, recent stud...

The genus Ononis has important value as traditional drugs and foods. In the present work, we aimed to assess the chemical profiles and biological effects of Ononis natrix subsp. hispanica extracts (ethyl acetate, methanol, and water). For chemical profile, total and individual phenolic components were detected. For biological effects, antioxidant (DPPH, ABTS, CUPRAC, FRAP, phosphomolybdenum, an...

The widespread relationship between salt excreting structures (e.g., salt glands) and marine life strongly suggests that the ability to regulate salt balance has been crucial during the transition to marine life in tetrapods. Elevated natremia (plasma sodium) recorded in several marine snakes species suggests that the development of a tolerance toward hypernatremia, in addition to salt gland de...

Natrix piscator like other snakes undergoes sloughing at regular intervals. The inter-sloughl period shows marked variations though is in general 20 days ; 2 days. Each inter-slough period may be divided into six stages. During each such cycle snakes show remarkable chanlges in the color of the body dorsally and the eye spectacles. These changes have a direct relationship with various stages of...
