A medium-sized sea snail, a marine gastropod mollusc.
The species is a sequential hermaphrodite. The slipper limpet normally lives in stacks of up to 12 individuals, with the largest at the bottom and with increasingly smaller individuals stacked on top of one another. The largest and oldest animals, at the base of a pile are female, the younger and smaller animals at the top are male. If the females in the stack die, the largest of the males will become a female. Breeding can occur between February and October with peak activity occurring in May and June. Roughly 80-90% of females spawn during May and June. Most slipper limpet females will spawn twice in a year, generally after neap tides.
