Definitions

1. A genus of filamentous green algae known for its branched, hair-like structures in aquatic environments
2. A type of freshwater algae consisting of thread-like filaments that form dense mats in lakes and streams
3. A group of green algae characterized by multicellular, filamentous growth used in studies of aquatic plant biology

Etymology: In ancient Greek, "khaitē" meant long, flowing hair, such as a mane or the bristles on an animal's back. The second element, "-phoros," comes from "pherein," meaning "to bear" or "to carry," which gives us words like "metaphor" and "semaphore." Put together, the name describes something that bears hair. The name was given to a genus of green algae whose threads look like fine bristles or hair. Those filaments cluster into the soft, dense mats that cover stones and submerged plants in lakes and streams. The term was formed in scientific Latin from Greek parts, so it was not a word used by the ancient Greeks themselves. Its meaning stays close to the physical look of the organism: the algae's hair-like threads.
