Angelwing

Cyrtopleura costata, or the angel wing clam, is a bivalve mollusc in the family Pholadidae. It is found in shallow parts of the northwest Atlantic Ocean and also in the North Sea coast of Scotland and the western coast of the Adriatic Sea in a remote area in the Marche region in central Italy. It lives on the seabed, where it digs its burrows through soft sand and mud using a very slow, revolving movement. These burrows can take years to form, and can reach a maximum depth of 8ft, but always below 3 feet (0.91 m) at the lowest tide.
