Bittium latreillii

Bittium latreillii is a small marine gastropod that belongs to the family Cerithiidae. This species is characterized by its elongated, spiral shell, which can be identified by its fine, closely spaced ridges. It typically inhabits the benthic zones of the Mediterranean Sea, where it can be found at depths shallower than 40 meters. Divers may encounter this species on sandy or muddy bottoms, often among seagrass beds or rubble areas. Its small size makes it less noticeable, but its unique shell structure can help in identification when closely observed. This species feeds primarily on detritus, grazing on organic matter available in its environment. Bittium latreillii exhibits a reproductive strategy common among members of its order, being gonochoric and utilizing a broadcast spawning method. The life cycle includes the development of embryos into planktonic trochophore larvae, which later metamorphose into juvenile veligers before reaching maturity. Encounters with Bittium latreillii during dives may be subtle, as they often blend into their surroundings. Divers should look closely at the substrate to spot these snails, which may be found in groups. The species is classified as Not Evaluated by the IUCN, indicating that its conservation status has not been assessed.
