Description

Cerithium zebrum has a distinctive growth to its shell where it starts as a solitary spiral cord that progressively strengthens over time giving its more pronounced spiral shell.[3] There are numerous threads within its shell that differentiate in toughness since when they form a keel it tends to have more fragile ribs or axial riblets due to its one spiral strand.[3] Its shell reaches about 7mm in length. Coming in many different colors from brown to beige, salmon, and even mauve. They also have a variable design that the shell has between being banded and unbanded.[4]

Distribution & Habitat

The distribution of Cerithium zebrum includes the Western Central Pacific.[5] The primary habitat of Cerithium zebrum is found among the rocky shores of the rugged and ever-changing conditions of the intertidal zone or tidal pools.[2] It's also said they can be found among the anchialine ponds which are in other words brackish water. (Brackish water is a mix between fresh and saltwater).[6]
