Dentalium [Dentalium]

Description

Dentalium, often referred to as 'tooth shells,' is a well-known genus within the family Dentaliidae. These tusk shells have a distinctive appearance, with long, cylindrical, and slightly curved shells that resemble elephant tusks. Dentalium shells are typically smooth, though some species may have fine striations. These marine mollusks are found in sandy or muddy substrates across various depths, from shallow coastal areas to deep-sea environments. They are detritivores, extending their foot to collect and feed on microorganisms from the sediment. Dentalium plays a significant ecological role and has been historically valued by various cultures for ornamental purposes.
