Fissidentalium [Fissidentalium]

Description

Fissidentalium is a genus of tusk shells known for their distinctively slender and elongated shapes, with a noticeable fissure or slit near the shell's opening. These mollusks inhabit marine environments, often burying themselves in sandy or muddy substrates. The unique structure of their shells allows for an efficient burrowing mechanism, as well as facilitating the flow of water for feeding and respiration. Fissidentalium species are found in various depths, from shallow waters to the deep sea, where they contribute to the benthic ecosystem by recycling organic matter.
