    Caught this cute little land crab while bug hunting. Area is around Palm Beach Florida, it was found in surprisingly dry conditions, under a large rock, sandy soil and dry leaves.

    I released it back to its general location after the pics were taken.

    This may help--I found a crab in Miami Beach, Florida under a large rock, with drying sand and leaves as well. I wonder if it is the same species. It was quite large! Check it out at 2:52

    @Aquarimax yours looks like a gecarcinid, which I think makes it Cardisoma guanhumi, although to me the colors don't look right. I guess it might be introduced.

    Thanks! Do you think the OP's crab is a juvenile of the same species?

    No, the carapace is the wrong shape. I'd say a different family entirely; I'll see what I can turn up.

    The OP's crab is a sesarmid, not sure what species

    Closest match is Sesarma cinereum. Well done.

    I believe Armases cinereum is the proper classification currently, awesome find!

    Do you find any of the big blue Cardisoma crabs? Can you find any more of those or other interesting crabs?

    I've caught the edible blue crabs, in a minnow trap and seen a few unidentified land crabs, but they have out ran me in most circumstances. I will try trapping for them.

    I see burrows everywhere, but I don't know who they belong too.

    He means the big blue land crabs. I think those might be uncommon due to overharvesting though.

    I think aquarimax caught a blue land crab.
