Natricinae

Barred grass snake Natrix natrix helvetica, copyright Benny Trapp.

Belongs within: Colubridae.

The Natricinae, watersnakes, are a group of snakes characterised by the presence of hypapophyses on all dorsal vertebrae, and minutely spinose hemipenes bearing one or more enlarged basal hooks. Members of the subfamily commonly hunt around water, feeding on small aquatic vertebrates.
