Eelgrass is a type of underwater plant found in shallow coastal waters, particularly in North America and Europe. It plays a crucial role in marine ecosystems by providing habitat and food for various species, including fish and invertebrates. Eelgrass beds also help stabilize sediments and improve water quality by absorbing nutrients. This plant has long, ribbon-like leaves that can grow up to three feet in length. Eelgrass reproduces both sexually, through flowers and seeds, and asexually, by spreading its rhizomes. Its presence is vital for maintaining biodiversity and supporting the overall health of marine environments.
