Many types of animals use and live in seagrass meadows. They are the main diet of dugongs and green turtles and provide a habitat for many, smaller marine animals, some of which, like prawns and fish, are commercially important. The offshore waters of Singapore also host many dugongs. A 2009 study revealed that mapped seagrass meadows have decreased globally by an estimated 29% since records began in 1879, and the rate of loss is accelerating.. To understand how meadows have changed over time, scientists turned to the emerging field of conservation paleobiology, which adds the fossil record … There are 40 times more marine animals in seagrass meadows than in the bare sand. Hunted for thousands of years for its meat and oil, the dugong distribution is currently fragmented. Seagrass live in the coastal waters of most of the worlds’ continents. It feeds on seagrass communities for subsistence, and hence, is found only in coastal habitats that support seagrass meadows. Seagrass meadows are important as nursery areas for juvenile fish and prawns. More information on the sites and how they are managed can be found at NatureScot’s Sitelink and on the Marine Scotland web pages for some sites. They grow in sheltered areas and trap sediment. For a number of sites detailed survey and monitoring reports also exist. Can seagrasses reduce the size of waves?

Meadow. Habitat: While seagrasses are ideal for juvenile and small adult fish for escape from larger predators, many infaunal organisms (animals living in soft sea bottom sediments) also live within seagrass meadows. Seagrasses support many important fisheries species, and slow down water movement which helps to stop shorelines and marshes from eroding. Seagrasses are the only flowering plants able to live in seawater and pollinate while submerged. Some animals that live in seagrass meadows are small and hard to see, while others are large and easily seen swimming and feeding in seagrass meadows. They represent only 0.05% of terrestrial plant biomass, but they store an equivalent amount of carbon per year, which makes them one of the most efficient carbon sinks on the planet (4). Seagrass beds abound with marine life, so it's critically important that we protect the seagrasses that grow in Scottish waters. But seagrasses are some of the planet’s most threatened ecosystems. Many different fish live in the meadows permanently like the … in seagrass meadows, particularly during their juvenile stage. It is one of the sub-categories within the section dealing with biodiversity of marine habitats and ecosystems.It gives an overview about the characteristics, distribution, zonation, succession, biota, threats, functioning and adaptations of the organisms that live in seagrass meadows. This article describes the habitat of the seagrass meadows. Like meadows on land, seagrass meadows are highly productive and support extensive food webs. They also help with coastal stability. Much like African savannas, these seagrass meadows are great places for animals to hunt and hide.
