Aquatic Animals
Aquatic habitat is any place filled with water in which plants or animals live. It
can be in fresh water or in salty seawater. Aquatic animals have certain distinct
features which help them to live in water, like :
Turtle Octopus Whale
± Most of the aquatic animals have gills to breathe. A few may have lungs.
± They have fins and tails which help them in swimming with water
currents.

water.
± Some water birds have webbed feet or paddle-like flippers as in turtles.
Turtle, whale, shark, water-snake, snail, octopus, starfish etc. are the
examples of aquatic animals. Blue whale is the largest water animal.
