Detailed Description
Dolichospermum cells can form heterocysts and akinetes. Heterocysts are specialized cells that fix nitrogen, allowing the population to survive when local nitrogen levels are low. Akinetes are thick-walled cysts that remain dormant in sediment until conditions are favorable for another bloom.
