Cymodoce
Cymodoce is a genus of marine flowering plants in the family Cymodoceaceae. The genus is commonly known as manatee grass or eelgrass. They are common in the coastal waters of tropical and subtropical regions around the world. These seagrasses play a crucial role in marine ecosystems, providing habitats and food sources for various marine organisms.
Characteristics
Cymodoce species are characterized by their long, narrow leaves that grow in clusters from rhizomes. The leaves are typically 10-50 cm long and 1-5 mm wide, with a smooth or slightly toothed margin. The plants can grow to a height of up to 1 meter. Flowers are small and inconspicuous, produced in clusters on the rhizomes. Fruits are fleshy and oval-shaped, containing one or two seeds.
Environments
Cymodoce species are found in shallow coastal waters, typically in sandy or muddy substrates. They prefer clear, well-lit environments with moderate water movement. These seagrasses can tolerate a wide range of salinity and temperature conditions.
Species
The genus Cymodoce includes several species, including:
- Cymodocea nodosa (Mediterranean seagrass)
- Cymodocea rotundata (Round-leaf seagrass)
- Cymodocea serrulata (Serrated seagrass)
- Cymodocea filiformis (Thread-leaf seagrass)
Ecological Importance
Cymodoce species are essential for marine ecosystems. They provide habitat and food for a wide range of organisms, including fish, invertebrates, and sea turtles. The seagrasses also help to stabilize sediments, filter water, and improve water quality. They are known to contribute to the overall health of coastal environments.
