Scutum ventral

from Wikipedia, the free encyclopedia
Underside of the striped water snake ( Amphiesma stolata )

The scutum ventrale (from Latin scutum "scale" and venter "belly"; plural scuta ventralia or short ventralia , "belly scales") are the scales on the underside of the body of most snakes . The scuta ventralia are enlarged scales that are arranged in a row. The anal (anal shield) in the area of ​​the cloaca and then the subcaudalia on the underside of the tail adjoin the ventral.

The number of ventralia in particular is an important determinant within the snake system .
