Cerithium: The Cerithium is a genus of small to medium-sized marine gastropod mollusks. These snails are part of the family Cerithiidae and are commonly found in the waters of the Comunidad Valenciana.

Physical Description:

• Shell: The Cerithium shell is elongated and turreted, with several whorls that display a spiral rib pattern. Typically, these shells have a high spire and a pointed apex.
• Color: The shell color can vary but often includes brown, gray, or white tones with occasional banding or spotting.
• Size: These mollusks usually range in size from a few centimeters to larger species often reaching up to 10 cm in length.

Habitat:

• Cerithium species are primarily found in shallow waters, often inhabiting sandy, muddy, or rocky substrates.
• They prefer coastal environments where they can be seen scavenging for organic matter.

Behavior and Ecology:

• Cerithium snails play an important role in the ecosystem as detritivores, feeding on detritus and decaying organic matter.
• They are known for their crawling locomotion and can often be spotted during low tide.

The Cerithium is recognized under local names depending on the region, and they contribute significantly to the geological history and biodiversity of marine environments in the Comunidad Valenciana.
