WHALE ADAPTATIONS:-

Whales are an amazing species that have evolved from land dwelling creatures millions of years ago (through ancestral blood lines) to the marine mammals we know today.

Whales are an amazing species that have evolved from land dwelling creatures millions of years ago (through ancestral blood lines) to the marine mammals we know today.Over the course of their evolution whales have made many adaptations towards their oceanic lifestyle so that they could survive and thrive in the underwater world.To help them adapt to the ocean whales developed echolocation, thick layers of blubber, modified lungs, better hearing and larger arteries among other things to ensure their survival and prosperity.

Adaptation

In the process of changing from a land to water environment, whales have undergone many physiological and morphological changes. Among these adaptations are: streamlined bodies for efficient movement through water; forelimbs modified into flippers to aid in steering; hind limbs internalized remnants reducing drag; tail positioned horizontally to achieve a powerful up and down propulsion; hair replaced with under-skin blubber to provide warmth and buoyancy; structure of nostrils changed to blowholes that can be sealed off under water and position shifted to top of head to give ability to breath air before the rest of the body surfaces and while swimming at the surface without lifting the head; highly developed hearing that relies on an internal system of air sinuses and bones to detect sound instead of external ears; lung capacity that enables them to exchange 80-90% of lung air volume(humans can exchange only 17-20%) ; reproductive organs internalized to prevent drag when swimming; and countercurrent heat exchangers in the tongue that enable the whales to take in gallons of very cold water during feeding and still not become hypothermic.
