The Atlantic Partridge Tun has a thin, balloon-like shell that is pale white to light tan, often with faint to dark brown bands. The shell has a short spire, a large rounded body, and raised ribs that encircle it. The snail’s mantle is white or pale gray, sometimes with small dark blotches, and its siphon is thick and fleshy.
The Atlantic Partridge Tun is a shy, solitary snail that can be found in sandy areas on the reef. It is a nocturnal predator that uses its large extendable mouthpart to consume other shellfish and sea cucumbers. Its saliva contains a mild acid that helps dissolve the shells of its prey.
