Well, I’m still not sure what kind of crab this little friend is. We did confirm that it’s a “true crab” in that it has four legs. So, it certainly is not a porcelain crab as we had initially suspected.
Over the past two weeks, I have noticed new behavior: the crab will come out for food and then promptly burrow itself back into the sand bed. When it was smaller, I think it was just hiding under sea shells. The burrowing is fairly new.
Still searching for an ID on this little one, so if you have any ideas please let me know!
@Alexopora any thoughts? See anything like this when you were looking up your mystery crabs?
