Adaptation in Aquatic Animals

Introduction to adaptations in aquatic animals

In process of evolution certain animals or plants undergo various structural changes which are external and internal in order to survive in the ecosystem. Such changes are referred as adaptations which can be divergent or convergent.

Adaptation is process of speciation where in formation of appendages will lead to appearance, development and existence of species in the ecosystem.

Similarly aquatic animals as they live in water in deep oceans or in fresh water need to possess many appendages which help them to survive in the water.


Types of Adaptation in Aquatic Animals

Back to Top

Aquatic animals live in water and need to have special morphological adaptations in order to survive in aquatic ecosystem. It is evident that the more time the animal spends in water the more would be the number of adaptations

  • Presence of streamlined body to reduce reduces friction as animal moves in water
  • Possess smooth, almost furless body by which aquatic animals or mammals move in water with minimum friction
  • In some aquatic animals dense fur is present which makes them warm.
  • Presence of waterproof feathers to wither away cold and prevent feathers from wetting. Presence of webbed feet which is formed from thin skin between the toes
  • Possess long legs and necks so that their body is out of water and helps them to move easily.
  • Presence of strainers in the mouth by which food particles in water are filtered out
  • Presence of flippers as convention measure for large surface
  • Presence of eyes on top of the head by which these animals hide fully in water.
  • Presence of nostrils on top of the head which help them to breath with little body exposed.
  • Presence of Blubber, which is a thick layer of fat helps as means of insulation.
  • Presence of eyelids which are transparent in nature
  • Presence of Flattened tails serve as paddles.
