Story Details

Whales and dolphins are marine mammals. They breathe air, give birth to live young, and nurse their babies with milk.

The blue whale is the largest animal ever known. It can reach 30 meters in length and weigh over 150 tons.

Dolphins are much smaller. A bottlenose dolphin grows about 3 meters long and weighs around 300 kilograms.

Whales and dolphins belong to a group called cetaceans. They are divided into baleen whales and toothed whales.

Baleen whales, like the humpback, have baleen plates instead of teeth. They filter tiny shrimp-like animals called krill from seawater.

Toothed whales, including dolphins and orcas, use sharp teeth to catch fish, squid, and other prey.

All whales and dolphins must breathe at the surface. They use a blowhole on top of their heads to take in air.

Some species can dive for over an hour. The sperm whale can reach depths of more than 1,000 meters.

Many whales migrate thousands of kilometers each year. They travel between warm breeding grounds and cold feeding areas.

Dolphins are known for their intelligence. They can use tools, solve problems, and work together to hunt.

Whales and dolphins communicate with sounds. Humpback whales sing long, complex songs that can last for hours.

Orcas are powerful hunters. They are top predators and can even take down large whales.

Whales and dolphins play an important role in the ocean. They help move nutrients through the water and support healthy ecosystems.

Many species are threatened by pollution, ship strikes, and hunting. Some populations are now endangered.

Protecting whales and dolphins helps protect the ocean. They are vital, intelligent, and extraordinary marine mammals.
