Identifying The Jackknife Clam Shell

Ensis directus (Conrad, 1843) English: America...The jackknife clam is an unusual shape and you’ll be able to identify it right away as the one that is sometimes called the “fingernail” shell.

Long (3-4 inches) and whitish colored, the shell is curved in a fashion resembling someones overgrown fingernail. We used to find them along the eastern shore of Florida.

My reference book says that the green jackknife (Solen viridis) is often found in north Florida and has more of a straight edge on one side, and the other type is called the minor jackknife (Enis minor).

I grew up in New England but spent most of my life living in central Florida. Now I'm back up north and blog about seashells, beaches, gardening, boating, fishing, hiking, photography, PKD, and my work as a designer for Zazzle. I move around a lot and try to discover the best in all places I live. Life may be tough, but it's not boring.

    I just got back from Old Orchard Beach, ME and found these shells all over the beach. I had never seen anything like it before. Thank you for being here to help me identify them!
