The earliest whales were land-dwelling!
Whales first marked their presence on Earth around 50 million years ago. In fact, last year, palaeontologists unearthed a 43-million-year-old fossil of a four-legged whale that walked on land and swam in oceans.

Dolphin is a type of whale!
Yes, you read it right. They belong to the class of toothed whales—those whales that have teeth and use them for hunting and feeding on their prey.
Whales are helping us fight the #ClimateCrisis!
Their iron-rich faeces create conditions for phytoplankton growth—the tiny plants that pull carbon from the atmosphere and produce oxygen.
Also, when whales die, the carbon becomes fuel for deep-sea ecosystems.
Humpback whales fast for several months.
While travelling long distances, these animals live off their fat reserve for 5-7.5 months of the year.
After returning to Antarctica from their tropical breeding grounds, they actively feed on krills for around 22 hours of the day!
Humpback whales and Bryde Whales trap their prey using a behaviour called bubble-net feeding.
They blow bubbles through their blowhole and encircle their prey. The prey is unable to overcome the bubble barrier and eventually fall prey to the trick.
A whale's tail is the key to identifying individuals.
Like human fingerprints or tiger stripes, each whale's tail is unique. The underside of a whale's fluke (its tail) may have scarring, notches, patterns and shapes that help to tell individuals apart.
