Keyhole limpets [Fissurellidae]

Description

Fissurellidae, or keyhole limpets, are distinguished by their unique shell structure, which features a notable hole or fissure at the top. This adaptation allows water to pass through the mantle cavity, facilitating respiration. Keyhole limpets are found on rocky substrates in intertidal and subtidal zones, where they feed on algae and detritus.
