Navicula caterva is a freshwater pennate diatom in the family Naviculaceae, forming aggregations in benthic communities on sediment and submerged surfaces. Its symmetrically lanceolate frustule and central raphe are characteristic of the large and cosmopolitan genus Navicula. As a bioindicator, it is used in assessments of freshwater quality and trophic status.

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.
