Years ago I caught a beautiful grass snake on a shoot. It had obviously just shed its skin and was a bright, glossy green with a well-defined neck stripe. I couldn't keep it, so I passed it on to a mate, who later passed it on again. He later told me that the snake had appeared on Blue Peter! It's my only claim to fame...
They have an amusing three-stage defence strategy:
1. Although completely harmless, they pretend to strike at you, the strike never making contact. If this doesn't work...
2. They play dead. It's very convincing. They flop over onto their backs and go completely limp, tongue dangling from the mouth. The only problem is, if you turn them over onto their bellies, they immediately roll over onto their backs again! If this doesn't work...
3. The snake exudes a foul-smelling liquid from its vent, then ties itself into knots, smearing the evil goo along its entire body. Ewww!
All in all, like most inedible, non-vermin species, they're best left alone and watched for the fascinating creatures they are.
