When referring to plants, the term describes land plants whose roots have adapted well to tolerate regular, prolonged submersion in water, as well as emergent and (occasionally) floating-leaved aquatic plants that are only partially immersed in water. Examples of semi-aquatic animals and plants are given below.
A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.
Green algae then invaded the land and started evolving into the land plants we know today. Later, in the Cretaceous, some of these land plants returned to the sea as mangroves and seagrasses. [72] Plant life can flourish in the brackish waters of estuaries, where mangroves or cordgrass or beach grass might grow.

Land plants began to diversify in the Late Silurian, from around 75] The colonisation of the land by plants was soon followed by arthropods and other animals. [ 76 ] Insects were particularly successful and even today make up the majority of animal species. [ 77 ]
For example, they recycle nutrients, purify water, attenuate floods, recharge ground water and provide habitats for wildlife. [16] The biota of an aquatic ecosystem contribute to its self-purification, most notably microorganisms, phytoplankton, higher plants, invertebrates, fish, bacteria, protists, aquatic fungi, and more.
Native to south-east Asia, this fish has strong spines on its pectoral fins that enable its body to "walk" across dry land. It travels from waterhole to waterhole, where it seeks refuge and makes ...
These plants create a buffer between the land and the running water system, protecting it from pollution and flooding. Additionally, these plants provide a large habitat for many wetland species, a large number of which are endangered or threatened.
