The Thing

I found a thing on the beach today. I have no idea what it is, so I left it at the Warden's hut for the National Trust wardensto find.

The Thing. It's around 2 feet long, it's soft and leathery and weighs 25 kg or so. Underneath is lighter in colour and hard to the touch. It must have been alive at one time but is it animal or vegetable?
