Diatoms are eukaryotic microalgae that play major roles in both the global carbon and silica cycles. They are largely distinguished by their silicified cell walls or “frustules”, which display a wide variety of shapes and nanostructures, depending on the species.

Entomoneis is a genus of raphid, pennate diatoms with a broad distribution in primarily marine and brackish environments. A notable feature of these diatoms is their relatively complex frustule morphology, including raised, bilobed keels on each valve face upon which the sigmoid-shaped raphe slit runs.

The sequenced strain, Entomoneis sp. UTEX 11IV18-2A FL, was originally isolated from Long Lake in Everglades National Park in April 2018 by researchers from the UTEX culture collection. The isolation site is a shallow, coastal, mangrove lake with highly variable salinity.
