Zostera is a genus of flowering plants commonly known as eelgrass. These aquatic plants thrive in shallow coastal waters and are found in both temperate and tropical regions. Eelgrass plays a crucial role in marine ecosystems, providing habitat and food for various marine species, including fish and invertebrates. Eelgrass beds also help stabilize sediments and improve water quality by absorbing nutrients and carbon dioxide. They are important for coastal protection, reducing erosion, and serving as a nursery ground for juvenile fish. Conservation efforts are essential to protect Zostera habitats, as they face threats from pollution, climate change, and coastal development.
