A genus of small marine snails, commonly known as slipper limpets, found in shallow ocean waters worldwide.
From Latin crepida (a type of slipper or sandal) + -ula (diminutive suffix), named because the snail's shell resembles a tiny slipper in shape.
Crepidula snails practice extreme sexual flexibility—individuals change sex based on social conditions, and they stack on top of each other in bizarre chains, making them a biologist's dream for studying animal behavior!
