Looked solid to me, posted an update of the other (top) side

Put it back where I found it

Haha I live at the beach. After the big storm the past few days there was dozens of these guys washed up. Most of them are long dead, and we just let nature be

I posted a picture of the other side for anyone who's interested

I'll update with the other side

This is very true these guys are ancient! Outlived the dinosaurs and maybe they'll outlive us too.

They are technically edible but they are rarely eaten. There's very little meat on them, they're mostly shell and more similar to spiders than crabs. The meat is supposedly rubbery. It's more common to eat their eggs especially in Asian countries but they have to be properly prepared or they can be toxic.

The scientist in me has to tell you that I am very confident in that a horseshoe crab would not survive this. Freeze tolerance is pretty rare, and there aren't any spiders (horseshoes crab modern day relatives) that can survive being frozen for a long period of time like this guy. Not to mention it's out been out of the water for a while by now.

I'm fairly certain it's dead but I also thought to myself if any animal could survive it would be this dinosaur mf
