- Whales are mammals just like we are. Just like us, they breathe air, have hair, are warm-blooded, give birth to live young, and feed their young milk.Whales are unique, beautiful, graceful and mysterious; they nurture, form friendships, innovate, grieve, play, sing and cooperate with one another. Here are some extraordinary facts about whales and their lives in the oceans.

- 1. WHALES ARE DEVIDED INTO TWO MAIN GROUPS
- There are two types of whales: the baleen whales and the toothed whales. Baleen whales, including humpbacks and blue whales, have fibrous 'baleen' plates in their mouths instead of teeth, which help them filter out and consume huge quantities of krill, plankton, and crustaceans. Whereas toothed whales, such as orcas, beluga and sperm whales, have teeth which enable them to feed on larger prey such as fish and squid.
- Humpback whales in the Southern Hemisphere live off their fat reserves for 5.5-7.5 months each year, as they migrate from their tropical breeding grounds to the Antarctic, to feed on krill.
- 2. HUMPBACKS WHALES DON'T EAT MOST FOR MOST OF THE YEAR
- 3. THERE USED TO BE THOUSANDS OF BLUE WHALES
- It's estimated that there were over 225,000 Antarctic blue whales before their exploitation in the 1900s. Today, blue whales are listed as endangered species, with less than 3,000 remaining in the wild.
- 4. USUALLY ONLY MALE NARWHALS HAVE A TUSK-THAT DEVELOP FROM TOOTH
- Used for foraging, displays of dominance and possibly fighting and breaking ice, the tusk is also a sensory tool used to detect changes in the sea around them.
- that's all from me, let other people know how amazing whales are.
- Let's protect the marine life!
