1. An aggregation of foraging hermit crabs. This activity caused 

 erosion of fine surface sediments leaving only the coarser 

 sediment components. 



2. A partially buried whelk moving through the sediment-water 

 interface. Note valve of the razor clam, a common prey 

 species of the whelk. 



3. A juvenile rock crab with shelter excavated under a shell 

 fragment. All individuals were observed in softshell 

 condition. Note molt (exuviae) at shelter entrance. 



4. A vertical burrow of the rock crab with exuviae at entrance. 



5. The individual rock crab removed from the burrow in the 

 previous photograph. 



6. Recent burrowing activity by a rock crab distributed anoxic 

 sediments on the surface outside the shelter entrance. 



7. Juvenile 4-spot flounder were observed foraging normally on 

 the dredged material site. 



8. A hermit crab leaving tracks on the sediment surface at the 

 periphery of the site. 



9. An association of starfish and sand shrimp (bottom of 

 photograph, partially buried) . The shrimp would winnow 

 through sediments disturbed by the tube feet of the starfish.

10. Hydroids fouling a clump of saltmarsh peat material. 



11. Hydroid colony attached to a partially buried peat clump. 



12. A winter flounder on the current sheltered side of a peat 

 clump. 



13. Mud snails attracted to the mucous trail left by a whelk on 

 the surface of the dredged material.

14. Remains of the molted exoskelton of a spider crab.
