Ocypode celadon Mahé, Seychelles.

Hello. This is my first post on here. The friend's dad found a little crab trapped in his saltwater pool near va beach in Chesapeake. We're not sure how it got there since we're at least 15 miles from the beach (not exactly walking distance for a little creature). We're not sure what kind of crab it is. Any help is appreciated.

FYI, we currently have him in a jar with some saltwater from the pool. It's not a good setup, I know. But we're not sure how to care for him until we know for sure what kind of crab he is. Thank you.

Curious about this. Been coming to NJ beaches for a long time, mostly Cape May.

I’ve never seen one of these before. What is it? Spotted in Ocean City, NJ. Thanks!

I bought an already made bioactive tank with what was labeled as a red devil crab (bought tank, food, and 1 crab for $130). The tank is 15 gallons and there was also a surprise 2nd crab that we didn’t know about until we got the tank home (we didn’t pay for 2 but I’m not mad). When I search Red Devil Crab, it gives Vampire Crab as a result. I assume these crabs are similar to Halloween Crabs? Red Land Crabs? Anyways, I set up a second tank temporarily, unfortunately it is 10 gallons so I’m working to get a bigger tank tomorrow. The tank is going to be 40 gallons with deep substrate (at least 6in.), very damp, hides and live plants. My house sits at 76 degrees so do they need a heat lamp? I plan to get a light bar for the tank though. Any other recommendations would be stellar :)

While on the beach(DeSoto) I found a crab claw in the water that looks clearly deformed. However, I was wondering how a class gets to this point and if anyone could ID the claw. (Sorry if the photos are bad they were taken in a rush)

Found this guy’s burrow while digging a big hole in a beach in northwestern Florida

I am raising a female 8cm and a male 9cm Rulicola crab in Korea.

These individuals were wild-caught specimens imported from the Caribbean Sea to Korea by a Korean importer in December 2025.

Can you believe the price per individual is over 400 dollars?

I started raising them in late February for the female and late March for the male, Korean time.

I am keeping them in a 1m 20cm enclosure.

I tried mating them briefly,

and the male is displaying aggressive courtship behavior.

This video is from two months ago, and the individuals are currently showing signs of molting,

so they are being isolated separately. I will post an update later.
