ID this sea creature I found washed up on the beach

Today, while walking along the beach of Gulfport, MS I came across an odd-looking, dead sea creature washed up on the sand. Only the hard parts were left, the soft bits had probably been eaten away. It was black, with a round carapace longer than my foot and bigger around than my spread hand. On the back end (or what I’m assuming was the back end) it had spiny horns and a thin tail. I didn’t see any claws or pinchers. What could this creature be? Some sort of Cthulhu-esque monstrosity?

A horseshoe crab.

Yes, I’d say it sounds like a horseshoe crab (which apparently is not actually a crab at all and is more closely related to spiders)

It sure sounds like a horseshoe crab, but a little out of range. It’s normally found in the Florida panhandle, but not far west. Who knows what kind of turbulent washup from the last fall’s storms brought in though.

I remember grabbing on to their tails as a kid on Long Island, and dragging them up from the water. They really look prehistoric, very cool, like trilobites.

Horseshoe crab

If it looked like Klingon’s head, it was a horseshoe crab (which isn’t a crab, btw).

Yeah, I think it was a horseshoe crab. It looks like the ones in those pictures. I read on wikipedia that horseshoe crabs are dwindling in numbers, and that you should ‘roll it over’ if you happen upon a live one that’s been tipped on it’s back so it can’t right itself. I would’ve rolled it over if it’d still been alive. :frowning:

BTW horseshoe crabs are totally harmless… if you see a live one you can pick it and inspect it without fear of getting bitten or pinched or stung.

So today at 7:30pm I was strolling down the same beach where I found the dead horseshoe crab. I see another laying on the sand on its back. Tentatively, I reached out and gave it a good poke with my shoe and holy shit it was alive!!! :eek:

I yelled, “Hold on, bud!” and found a stick to shove him over on his belly. I then used the stick (I know they’re not poisonous, but I still didn’t want to touch him) to push him down towards the water. Me and the horseshoe crab, working together, got him down to the shallow water from about six feet up on the beach. I could see his little legs wiggling under his armor, and his little tail waved back and forth as he scrunched his way down. Once I got him good in the water, I figured him and the tide could take it from there. I said to him, “Now swim on back to Florida and make little horseshoe crabs,” wished him good luck, and took my leave. I hope this is good karma so if I come back as a horseshoe crab in my next life, and I’m laying helpless on a beach, someone will come around and flip me over.
