Cerithium scabridum

Cerithium scabridum is a marine gastropod mollusk characterized by its shell, which varies in size from 10 mm to 25 mm. Its shell structure and form can help distinguish it from other species within the Cerithiidae family. This species typically inhabits the Red Sea, Persian Gulf, Arabian Sea, and Mediterranean Sea, thriving in shallow waters where it can be found on both soft and hard substrates. It is commonly located at depths ranging from 20 to 40 meters, although most occurrences are shallower than 30 meters. As a herbivore-deposit feeder, Cerithium scabridum primarily consumes organic matter found in its environment. It plays a role in the benthic ecosystem, contributing to the breakdown of detritus. The reproductive strategy of this species involves being gonochoric and utilizing a broadcast spawning method, where embryos develop into planktonic trochophore larvae before transitioning into juvenile veligers and eventually reaching maturity. Divers may encounter Cerithium scabridum while exploring sandy or mixed substrates, where it may be seen grazing or resting. Observations of this species can be made year-round, and it is generally harmless to humans. The conservation status of Cerithium scabridum is not evaluated, indicating a lack of specific data regarding its population trends.
