Burrowing crustacean - Chiridotea coeca

Burrowing crustacean - Chiridotea coeca
Great Island, Cape Cod National Seashore County, Massachusetts, USA
June 3, 2008
Size: ~7 mm
I know this is destined for 'frass', but I'd be grateful if anyone could help me figure out what this is. Found many of them burrowing just below the surface of the beach.

Moved from Isopods.

We found them too!
We found these critters at Ocean Beach in Connecticut. I asked at Mystic Aquarium for identification: Mole Crab. They look like a shrimp without the long tail or fan. Very cool to watch them dig through the sand to bury themselves.

Didn't realize there were any of these on the guide
This is Chiridotea coeca. Not at all a mole crab, Emerita talpoida.

Dorso-ventrally compressed body; large, triangular plate-like pleotelson (last abdominal segment) and posterior ventral gills (both are most visible in ventral image), and body divided into three zones - cephalothorax, pereon, and pleotelson - reminds me of a marine isopod. Quite a diverse group.
