Oh! So you don't want to catch/eat them and just want to see something cool? Park at the Long Point Boat Ramp in Wickford, then walk along the coast to the left/west. Thousands and thousands of little sand crabs that will be out sunning themselves or whatever, but scurry into their holes when you get within 10 feet or so. Walking/riding through there feels like Moses parting the Red Sea. I have no idea how much longer they'll be around...I know nothing, but I don't imagine they hang out all winter...?
