Florida Spiny Jewel Box
Arcinella cornuta Conrad 1866
About 1-1/2 inches in length, the Florida Spiny Jewel Box is a bivalve found from the coasts of North Carolina to Florida and Texas. It is white; the interior may show tinges of pink or red. The shell itself is thick and heavy for its size. Fresh shell specimens will have more distinct erect tubular spines on the 7-9 rows (ribs) across the shell, radiating from the beak. Notice the rounded bulge near the anterior margin.
