Maybe should go in the invertebrates section, but it is an ID question.
These things are up to about an inch long, living buried in sand. I was catching them just above the water line, but presumably they are present underwater also. They swim reasonably well when dropped in the water. These were caught on the north shore of the Delaware bay. I have seen something similar (indistinguishable to me) on Coronado Island off San Diego. The water was essentially full salt at this point. The only other sign of life on the beach was horseshoe crabs. critter 1.jpg 144.43KB 0 downloads critter 2.jpg 131.68KB 0 downloads critter 3.jpg 71.34KB 1 downloads critter 4.jpg 68.16KB 0 downloads critter 5.jpg 90.92KB 0 downloads
