Taxonomic Group: | Cyanobacteria |
Trophic Status: | Autotrophic |
Size Range: | 2-3 ?m wide (LUMCON Guide) |
Key Characteristics: | Terminal cells usually narrower and longer than the intercalary cells, sometimes much longer; terminal cells also contain fewer gas vacuoles and less pigment, and thus sometimes appear empty; filaments often in large bundles |
Confused With: | Anabaena species, which can sometimes be found in bundles, but the terminal cells are neither almost devoid of visible contents nor notably narrower than the central ones |
Toxin: | Anatoxins, cylindrospermopsin, saxitoxins |
