Gmelin 1788 Category: Nitzschioid
TYPE SPECIES: Bacillaria paradoxa Gmelin
Sorted by maximum length (smallest to largest)
The raphe of Bacillaria species is located within a raised keel. In contrast to the excentrically positioned raphe and keel of Nitzschia, the raphe of Bacillaria is centrally positioned along the apical axis. The striae are distinct and relatively coarse. Living cells form colonies. The colonies are joined by silica hooks near the keel, and these silica hooks allow the cells to slide past one another in coordinated movements.
Bacillaria is found in marine, brackish, and freshwaters with high conductivity and often nutrient rich conditions.
