This habitat covers the oceans in the broadest of manners. A marine environment can cover any water environment from the shore line to the deep Mariana Trench in the Western Pacific Ocean.

A marine environment could be made up of vast empty sand or rich coral reefs which support complex ecosystem. It includes seaweeds, sea grasses and mangrove areas. The temperature can range from the polar caps to the Indian Ocean but generally the temperature for an area of ocean does not fluctuate much during the course of the year in comparison to land temperatures.

Below you will find what can be seen as Marine National Parks. They may form part of the National Park or make up the whole National Park.

*This work is ongoing, so please check back from time to time.

*Classifying areas of land into categories is difficult and can be very complex. For ease I have only selected seven major habitats to classify National Parks into and apologise for generalising the classification system.
