a crustacean, right?
Odiorne Point State Park, Rye, Rockingham County, New Hampshire, USA
July 24, 2010
Some sort of marine invertebrate I found while looking for crabs among the tidepools. Very small, perhaps some sort of shrimp?

Moved
Moved from Mysid Shrimp. Two views together are needed for a specific ID in New England: the telson and the base of the antenna.

Moved
Moved from Crustaceans.

I believe that Jonas is correct--based largely on this image from Salt Water Marshes in Mid-Coast Maine.

This is a mysid shrimp
a.k.a. an "opossum shrimp", though they aren't true shrimps which are under Decapoda, while mysids are under the suborder Peracarida with isopods and amphipods.

You should get a second opinion, though, as I am not an expert.

maybe fairy shrimp?
I'm no expert, but it resembles some web images of fairy shrimp. Just another possibility to consider before an expert can give you a real ID.

Hmm...
I would surmise this is some sort of larval crustacean. It could be anything from a shrimp to a lobster. I'm sure if you can find some resources on larval forms of crusties online. Try the NOAA web page first. They have a ton of resources on biology.
