With advice for singles:
Fiddler crabs check out at least 100 potential mates before making a decision. While we acknowledge that figuring out how to get along with difficult people is a big part of marriage, how can it hurt to decide carefully - even though it's guaranteed that you will end up with a flawed human - or crab? (Hopefully, not with crabs.)
I didn't realize we have three species on the East coast. I guess I am mainly familiar with the ubiquitous and delightful Atlantic Marsh Fiddler of the Cape Cod salt marshes and tidal flats. It always cheers me up to see them.
These cute mud-eating crabs with their little holes all over the high tidal mudflats are all bark and no bite, have gills but breathe air, do not make good bait, and live in colonies in which they seem to spend most of their time threatening eachother. At high tide, they retreat into their burrows and shut the door. Up here, they hibernate down there all winter.
Egrets and herons will eat them. Raccoons, too.
