Fu’sus is a genus of gastropods, which are allied to the British whelk and American conch, and which include, in F. colosseus, perhaps the largest living gastropod. The shell is fusiform, with a many-whorled spire and a long, straight canal. One species, F. antiguus, is dredged in the seas about Great Britain to be sold in the London markets as food.
