Let's go crabbing

Boy with a net and chicken leg on a string
Those pesky little pinchers, who make us think twice about standing barefoot in the shallows, are great fun to catch. But be sure to approach them from behind, or their claws will be ready for you! Pick them up from their crusty mid-section, and you'll be safe. Some "spider" crabs can get as big as 10"-12" across (including their long legs), while the smaller "fiddler" crabs are well camouflaged with the sand and can actually swim up off the bottom.

The endangered horseshoe crab

A horseshoe crab cannot live without its tail,
so always pick it up by its sides.
Horseshoe crabs are often referred to as living fossils as they have been around since before the dinosaur age. Recently scientists, including those at the Woods Hole Marine Biological Lab, have discovered that they offer valuable medicinal benefits. The horseshoe crab has no known enemies other than migratory birds who eat their eggs. Despite its dangerous appearance, the tail is merely used for digging in the sand and righting itself if it gets overturned.

A traditional coastal activity -- shellfishing

Men clamming the flats
Clamming is a Cape Cod ritual that dates back to the Native American Indians. Equipped with knee-high rubber boots, special rakes, and a steel basket, clammers dig for these bivalves in the tidal mud flats of Cape Cod Bay. Ever hear the expression “Happy as a clam during high tide”? That’s because clams are usually caught during low tide. Before venturing on a clamming expedition, be sure to check with the town regarding regulations and the need for a permit.
