Spirogyra Longata interact with their surroundings in peace.  Nearby fish such as the Northern Pike, Largemouth Bass, and Channel Catfish nibble on this algae. As other herbivores feed on it, it can easily reproduce sexually or asexually.  Rarely they can be found to be invaded by parasitic protists that cause them to die off.  Humans don't have much interaction with this green algae, other than while doing freshwater recreation activities.  This green algae can live side-by-side with related organisms with no problem or competition.


Filamentous algae can be found in a palate ranging in green colors.  Here we see an almost fluorescent green Spirogyra found in and around the Alabama waterways.
