SPECIES INFO
There are numerous species of thread algae. This species has not been identified.Green Algae Subgroup (Chlorophyceae) has over 6,000 different species. Included in this category are the thread-like freshwater algae in the genus Spirogyra that can be found attached to rocks in almost any freshwater body in North America. In stagnant water they also form colonies that float on the surface.
Green Algae Group (Chlorophyta) is usually broken into three main categories: Charophyceae, typical Chlorophyceae, and Euglenophyceae. The Euglenophyceae can also be placed as a separate group in that they contain animal-like features. They are placed here in a separate class as opposed to making them one of the three subgroups of green algae.
Protista kingdom (sometimes spelled as Protoctista) contains numerous phyla including unicellular animals and algae. Generally, these are aquatic life forms. The number of species is difficult to estimate, and it might be as low as 60,000 and as high as 200,000.
There is discussion among scientists as to whether this group of lifeforms should be split into two different kingdoms. One for those that make their own food, and the other for those that eat food. They suggest: Chromista and Protozoa.
Although herein we follow conventional norms and recognize 9 phyla, it has been suggested there might be 50 different phyla herein. These lifeforms have been found as far back as 1.2 billion years ago.
