Strange but true. This island is home to the German Hairy Snail, and the Two Lipped Door Snail.
I looked around the edge as it is now illegal to walk on the Ait, never saw no snails.
I did not believe it either so I Googled it, its true they are there.
What with the sewage outlet and all those lovely snails this is a nice place to be.
Did you notice a tiny bit of sarcasm there
