Maiden's Hair
Maiden's Hair algae provides a very soft appearance combined with all of the other benefits of macroalgae. Maiden's
Hair looks like a thick mat of bright green carpet, adding an intense green color and soft flowing motion to any marine
aquarium. Most Maiden's Hair is collected off of the islands of Tonga or Fiji, and comes already attached to a small
piece of live rock.
There are several different species of macroalgae available to the marine hobbyist. The benefits of macroalgae cannot
be understated, so if you have a marine setup, be sure to include a few of these special "plants" and your fish will reap
the rewards.

The green algae (singular: green alga) are the large group of algae from which the embryophytes (higher plants) emerged.
As such, they form a paraphyletic group, although the group including both green algae and embryophytes is monophyletic
(and often just known as kingdom Plantae). The green algae include unicellular and colonial flagellates, usually but not always
with two flagella per cell, as well as various colonial, coccoid, and filamentous forms. In the Charales, the closest relatives of
higher plants, full differentiation of tissues occurs. There are about 6,000 species of green algae. Many species live most of
their lives as single cells, while other species form colonies or long filaments.
A few other organisms rely on green algae to conduct photosynthesis for them. The chloroplasts in euglenids and
chlorarachniophytes were acquired from ingested green algae, and in the latter retain a vestigial nucleus (nucleomorph).
Some species of green algae, particularly of genera Trebouxia and Pseudotrebouxia (Trebouxiophyceae), can be found in
symbiotic associations with fungi to form lichens. In general the fungal species that partner in lichens cannot live on their
own, while the algal species is often found living in nature without the fungus.

Does it really help
in classifying the
