From land to open sea - marine habitats
Marine habitats include those on the coast and
shoreline and out to sea, both the water itself and the seabed.
These habitats vary greatly:
Coastal areas range from rocky cliffs, to sand dunes and salt
Estuaries, where rivers meet the sea, are important links between
the land and the water.
The shoreline is another meeting place – this is the land between
low and high tide. Known as the intertidal, it has special
communities of animals and plants that can cope with being both
immersed in seawater and exposed to air twice a day.
In the open sea, often out of sight and out of mind, there is a
large diversity of thriving habitats and species from sponges,
anemones and other plant-like animals that form our very own reefs,
to areas of sand and gravel that support many creatures that, in
turn, are an important source of food for other animals such as
fish and seabirds.
