Summary
[edit]DescriptionEchinarachnius parma (6806969731).jpg |
English: EPA New England divers unexpectedly came upon a very large gathering of sand dollars at Folly Cove in Gloucester, Massachusetts.
These sand dollars (Echinarachnius parma) and a few baffled hermit crabs were photographed in 25 feet of water. This unusual scene was captured during a dive to monitor invasive species in the area. From the diver, "Folly Cove is one of my favorite spots to look for invasives. This work allows us to photodocument the presence of many different native species, such as these sand dollars and the attractive shorthorn sculpin." ~Phil Colarusso, U.S. EPA |
