Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Cylindrotheca closterium is an elongated, needle-shaped marine and brackish water diatom common in coastal sediments, intertidal mudflats, and benthic biofilms worldwide. Its spindle-shaped silica frustule tapers to fine points at both ends. This species is an important primary producer in estuarine and shallow coastal ecosystems and can form dense mats on sediment surfaces.
