Welcome to the world of Spirogyra Longata!

Spirogyra Longata in a freshwater pond

DAD! My carp got caught in the slime againnnnn!  Sound familiar? A wonderful summer afternoon bonding with some fishing poles and the sun, and that wonderful thing we call green algae drags this fishing trip down.  Spirogyra Longata, the distasteful, scummy looking masses floating towards the top of bodies of freshwater getting in the way of your afternoon swim or fish are ACTUALLY quite beautiful in structure and reproduction.  It is easily identifiable with its long green filamentous structure and freshwater habitat.  Though this water looks dirty or even polluted, it is actually eutrophic.  No need to worry!  Most refer to this tangling mess as green algae, but it can also be known as mermaid tresses or water-silk.  This webpage will disclose all you need to know about this filamentous green algae including:  Classification, Habitat & Geography, Adaption, Nutrition, Reproduction, Interactions, and other Interesting Facts! Continue exploring for the Classification of Spirogyra Longata.

The nucleus is suspended in the cell vacuole by threads of cytoplasm. Each filament measures between 10 and 100 micrometers in width and these filaments have root-like structures to help themselves attach to the substratum.
