I have seen quite a few small snakes with ZASKRONIEC (Common grass snake) over the summer.
I will point out that there are no snakes in my country of origin, so there is nothing common about these guys for me :)
Playing dead also in ecdysis.
Not being venomous, the snake's only defence is to produce a garlic-smelling fluid from the anal glands, or to feign death by becoming completely limp. They may also perform an aggressive display in defence, hissing and striking without actually opening the mouth. They rarely bite in defence. It is claimed that they may also secrete blood from the mouth and nose whilst playing dead.
So it's defence is garlic farts and a nose bleed. Nature truly is wonderful :)
