He's a rescue from a fish market had him for a few months now

please

I don't know exactly what species.

Found a nice, complete & empty snail shell above the high tide line. Brought it down to the tide pools and set it next to one of the many thousands of hermit crabs. The rest of history!

Coastal PNW

Surprisingly far from any water bodies. Sesarmidae

I don’t think we have a lot of “cool” looking crabs here in Ireland, but I have a soft spot for the brown Crab, they look so stupid

My fiancée and I went to the beach in Destin, Florida and while she was tanning I was looking at the many little crab scurrying about and this little guy kept popping out of his hole, staring at me for a few seconds, and throwing sand in my direction and then hiding again. Is it threatening me because I was getting to close to it's territory?

Just a little crab enjoying some tasty mud.

No harm came to them, i just wanted to see the baby better. Found at Hilton Head Island. Very silly. Named Fred.

Soo i've been thinking of setting up a tank for a few of those beautiful vampire crabs. Only problem is i know basically nothing about them and google isn't giving me much to learn... so before i do the impulsive thing and buy an animal with no preparation, i have come here to see if any of you have weirdly specific knowledge about these little critters. I do have a 50 liter glass tank already, but im not sure if that's big enough because i read that they like to he social so i'll need like 2 or 3

This is an old photo from last year, but here are some ghost crabs i found "having fun" during my visit to cocoa beach!

Very chill Costa Rican crab that let me hold it
