Overview
Mactridae, also known as trough shells or duck clams, is a family of marine clams of the order Veneroida.
Trough shells burrow in sand or fine gravel and never in muddy substrates. They have two short siphons, each with a horny sheath. The shell is shaped like a rounded-cornered equilateral triangle and there is a slight gape at the posterior. Each valve bears two cardinal teeth with four lateral teeth on the right valve and two on the left. The foot is white and wedge-shaped. They mostly inhabit the neritic zone.[1]
