Pacific Half-Slipper Snail

Crepipatella lingulata

Crepipatella lingulata is a marine gastropod mollusk characterized by its distinctive shell shape. This species can be identified by its half-slipper appearance, which sets it apart from other snails. It inhabits the Northeast Pacific region, particularly along the coasts of Canada. The Pacific Half-slipper Snail typically resides in benthic environments, often found on rocky substrates and in shallow waters. Most recorded sightings occur at depths shallower than 40 meters, with a significant number also found below 180 meters. Feeding primarily on algae and organic matter, this snail plays a role in the ecosystem by grazing on these resources. The reproductive strategy of Crepipatella lingulata involves gonochoric spawning, where embryos develop into planktonic trocophore larvae before transitioning into juvenile veligers. This life cycle allows for a broad distribution of the species as larvae drift in the water column. Divers may encounter the Pacific Half-slipper Snail while exploring rocky reefs or tide pools. Observing this species can be an interesting experience, as they may be found clinging to surfaces or moving slowly across the substrate. The conservation status of Crepipatella lingulata has not been evaluated by the IUCN, indicating a lack of specific data on its population trends.
