Threats to the smooth snake
The main reason for the scarceness of smooth snakes is the destruction of their habitat - a problem they share with the sand lizard, with which they share much of their remaining territory.

As a defensive mechanism, they can secrete a foul-smelling substance from their anal glands. This is designed to put off predators!
