Arca imbricata, or the Mossy ark clam, is a clam in the family Arcidae. It can be found along the Atlantic coast of North America, ranging from North Carolina to the West Indies, Brazil, and Bermuda.[1]
Description
Arca imbricata grows to about 2 ins (5 cm) in length. The valves have a roughly rectangular shape with a rounded anterior end and a slightly pointed posterior end. They are usually purplish-white in colour, but live specimens are covered in a thin brown protective periostracum. There are some distinct ribs on the posterior end and the margin is smooth. The hinge is long and straight with a number of fine teeth.[2]
