Rhinoceros
Viper
The
striking colour and pattern of the rhinoceros viper make it an attractive
snake. Their skin has a velvety appearance especially after shedding
because they have keeled scales rather than smooth scales. Smooth
scales make snakes look shiny while keeled scales give a velvety
appearance. The name, keeled, is derived from the slight ridge that
runs down the centre of each scale on the sides and back of the snake.
