The photographs below show a clutch of 18 hatched Grass Snake eggs, plus the skin from the female who layed them.
Going by the size of the skin she was a very big snake. I have sloughed skins from 120cm snakes and this skin was considerably bigger!
As the young snakes hatch, they use a small egg tooth to cut through the leathery egg casing. They lose this tooth not long after they have hatched.
Hole where young snake has broken through.
