What Is a Whale?

Whales are marine mammals belonging to the order Cetacea, which also includes dolphins and porpoises. They breathe air, give birth to live young, and nurse their offspring with milk.

Types of Whales

  • Baleen whales – filter feeders like blue and humpback whales
  • Toothed whales – predators like orcas and sperm whales

Where Do Whales Live?

Whales are found in all of the world’s oceans, from polar regions to tropical seas. Many species migrate thousands of kilometres between feeding and breeding grounds.

What Do Whales Eat?

Diet depends on species. Baleen whales consume krill and plankton, while toothed whales hunt fish, squid, and other marine animals.

Why Are Whales Important?

Whales play a key role in ocean ecosystems by recycling nutrients, supporting marine food chains, and even helping regulate carbon levels in the atmosphere.

Are Whales Endangered?

Many whale species have recovered since the end of commercial whaling, but others remain threatened due to ship strikes, entanglement, climate change, and ocean pollution.
