The big, blubbery world of whales 🐋

Whale Is...

Mammals, not fish – They breathe air through lungs, are warm-blooded, give birth to live young, and feed them with milk.

Belong to the order Cetacea, which includes whales, dolphins, and porpoises.

Split into two main groups:

1. Baleen whales (Mysticeti) – filter feeders with baleen plates instead of teeth (e.g., blue whale, humpback whale).

2. Toothed whales (Odontoceti) – have teeth and hunt prey like fish or squid (e.g., sperm whale, orcas).

2. Famous Species

3. Anatomy & Adaptations

Blowhole: on top of the head for breathing.

Blubber: thick fat layer for insulation and energy storage.

Echolocation (toothed whales): using sound to navigate and hunt.

Baleen plates (baleen whales): keratin filters to sieve plankton and krill from water.

4. Diet

Baleen whales: krill, plankton, small fish.

Toothed whales: squid, fish, seals, sometimes other whales.

5. Life Cycle

Gestation: 10–18 months depending on species.

Calves nurse for months to over a year.

Lifespan:

Baleen whales: often 50–90 years.

Bowhead whales: can exceed 200 years!

6. Behavior

Migration: Many species travel thousands of km between feeding (cold waters) and breeding (warm waters) grounds.

Songs & communication: Especially complex in humpbacks.

Breaching: leaping out of the water — may be communication, play, or parasite removal.

7. Threats

Whaling (historically reduced populations massively).

Ship strikes, entanglement in fishing gear.

Noise pollution affecting communication.

Climate change altering food supply.

8. Fun Facts

A blue whale’s heart can be the size of a small car.

Whale earwax builds up in layers — scientists can read it like tree rings to learn their age.

Sperm whales can dive over 2,000 meters and hold their breath for more than an hour.
