A type of sea snail with a large, smooth brown or cream shell with zig zag stripes, containing an animal which has no operculum on its foot. Those found in markets are likely to be false bailer shells. It is found all round the coasts of Australia but it is illegal to trap it in some areas. Fishing of these shells is now mainly confined to the the south east, and bailers are sold in Sydeny Fish Market. Called the bailer shell because it holds water and could effectively be used to bail out water from a boat.
