Navicula digitoradiata is a pennate freshwater diatom with a lanceolate outline and finger-like radiating striae extending from a central nodule. It inhabits epipelic benthic zones in rivers, lakes, and brackish environments across temperate and subtropical regions. This photosynthetic diatom contributes to sediment surface biofilm communities.

Navicula hambergi is a boat-shaped pennate diatom found in freshwater benthic and planktonic habitats. Its symmetrical, lanceolate silica frustule with a central raphe is typical of the large Navicula genus. This species contributes to aquatic primary production and is used in biological monitoring of freshwater quality, as different Navicula species have varying tolerances to pollution.
