It's a crab obviously ... a deceased crab. But what the hell is that sticking out of its arse?!

Pic quality not great but it's a video snapshot from a mobile!

Sweet Zombie Jesus ! I dare say that looks to be a missing piece of the Urn of Eryines of ancient Sumeria! Whatever you do don't hold it up to your ear, the screams of a thousand boiled children will haunt you until you lose your mind. I recommend hurling it right back into the sea from whence you found it before all is lost

It's a Black Crab by the looks, fisherman commonly use them as bait.........apparently.

That name must have taken them ages to think up.

"I have found a crab...it's black"

I must admit, I was slight embarrassed by my answer and was awaiting the comments. Just wish their was a Latin name.

Scylla serrata

Its just a flap, that normally sits under the crabs abdomen, co,s its dead its flappin out the back...........true. ........mm

*sigh* that's a very boring explanation, mm

but thanks anyway

So, when you die the flaps open? Doesn't sound very dignified to me

The indignity of being female, the male crab has a much smaller flap.

you don't want to see what hangs out when the male crab dies.

Is the flap kinda like a little crabby sporran then?

No thanks, I actually enjoy eating them.
