Brief Summary

provided by Ecomare
It's not hard to understand why Chaetomorpha is also called green hair algae. This thready seaweed looks like spools of dull green transparent ... hair. If you look closely, you can see rows of cells, even with the naked eye. There are many members of the Chaetomorpha family. Some grow from a fixed base, others grow while floating. During the summer, the tidal flats can be covered with large masses of Chaetomorpha. Although it seems to suffocate everything lying underneath, it also offers protection to gammarids, shore crabs and laver spire shells. Chaetomorpha is used in marine aquaria to filter the water. It converts nitrogen wastes produced by the fish into plant food!

Chaetomorpha

provided by wikipedia EN

Chaetomorpha is a genus of green algae in the family Cladophoraceae.[1] Members of this genus may be referred to by the common name sea emerald.

Description

Algae of this genus are made up of macroscopic filaments of cylindrical cells.[2] The genus is characterized by its unbranched filaments, making it distinctive; its closest relatives are branching species of the genus Cladophora.[3]

Species

There are about 50 species.[3] Species include:[1]

Uses

These algae are popular with aquarium hobbyists. Dumping of aquarium specimens into waterways has led to the establishment of nonnative Chaetomorpha populations, which degrades ecosystems when the algae become invasive species. Biologists recommend boiling, microwaving, freezing, or desiccating aquarium Chaetomorpha before disposing of it to avoid inadvertent releases.[4]
