Types of habitat:
There are three types of aquatic habitat - Freshwater, marine, and coastal.
1. Freshwater habitat: These habitats consist of the water bodies filled with fresh water, like rivers, lakes, ponds, streams etc. The water has very less amount of salts dissolved in it.
2. Marine habitat: Aquatic habitats where the water has a high content of salt are known as marine habitats. Oceans and seas are examples of marine habitats. The marine habitat has a lot more organisms in it than the freshwater habitats. Organisms like corals, shelled animals, sponges, jellyfish, sharks and many others are found in this habitat.
3. Coastal habitat: This is the habitat formed in the place where land meets the sea. Estuaries are formed in these areas, and trees like mangroves can be found here.
