Myrionema
Myrionema is a genus of brown algae belonging to the family Myrionemaceae. It is characterized by its filamentous, branched thallus, often forming a tuft-like structure. The genus is widely distributed in marine environments, typically found growing on rocks, shells, and other submerged surfaces.
Common Names
Myrionema species are commonly known as "myrionema" or "thread algae," reflecting their thread-like appearance.
Characteristics
Myrionema species have a distinct morphology:
- Thallus: Filamentous and branched, forming a tuft-like structure.
- Holdfast: A basal attachment structure that secures the alga to the substrate.
- Reproductive Structures: They produce zoospores, which are motile spores capable of independent movement.
Environments
Myrionema species are found in a variety of marine environments, including:
- Intertidal Zones: Exposed to both air and water, often found on rocks and shells.
- Subtidal Zones: Permanently submerged, growing on rocks, shells, and other submerged surfaces.
- Estuaries: Brackish water environments where fresh and saltwater mix.
