It took me a short while to notice that this was a stuffed snake and not a real one. I don’t like getting too close to them to inspect them, but it soon became apparent that it wasn’t moving and a lazy snake was hardly likely to stay in that position.
It’s fake nature was more obvious when I zoomed in. I don’t trust snakes though, they can be shifty little things, so I’m glad I checked.
Although there were other clues, like this sign that mentioned at the moment there wasn’t any “living” snake in the terrarium.
There should have been a grass snake here, for which the German is ‘Ringelnatter’. The word ‘natter’ can mean a snake or adder and it’s what came across into English as ‘nadder’ for snake. In middle English ‘a nadder’ became ‘an adder’, so by the seventeenth century or so the spelling had changed.
