Atlantic Kitten Paw
Plicatula gibbosa (Lamarck, 1801)
Family Plicatulidae
The Atlantic Kitten Paw, or "Kitten Paw" for short, is fairly common on S. Hutchinson Island beaches. Kitten Paws are small shells (.75") and come in a variety of colors with a different numbers of toes. Three toes being the fewest up to maybe a dozen toes in some shells. They attach to other shells and there's a flat area at the bottom on the paw where they have been attached.
