Meaning of Aquatic Habitat

An aquatic habitat is a body of water in which organisms live. Such organisms are called aquatic organisms e.g. fish, algae, crabs, etc.

Types of Aquatic Habitat

There are three types of aquatic habitat namely:

  1. the marine/salt water habitat;
  2. the estuarine/brackish water habitat and
  3. the freshwater habitat.

Marine Habitat

The marine habitat is a body of salty water. It is made up of the shore and open sea. Examples are the oceans and seas.

Characteristics of Marine Habitat

  1. High salinity; about 35.2 parts of salt per 1000 parts of water.
  2. High density of about 1.028; this enables organisms float in it.
  3. Pressure increases with depth.
