Ceratoneis closterium is a slender, crescent-shaped marine and brackish diatom with finely tapered, curved cell ends. It inhabits coastal marine and estuarine planktonic environments across temperate to tropical seas. This photosynthetic diatom contributes to phytoplankton communities and serves as food for zooplankton in coastal waters.

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.
