Cetacean

Cetaceans are super cool animals that live in the ocean! They are mammals, just like us, which means they breathe air with lungs and baby cetaceans drink milk from their moms. But unlike us, they have fins and tails made for swimming!

There are two main groups: toothed whales, like dolphins and orcas, that have teeth to catch slippery fish, and baleen whales, like blue whales, that have special filters in their mouths to eat tiny shrimp.

Cetaceans are found in oceans all over the world, from the super cold Arctic and Antarctic waters to the warm tropical seas. Some, like the beluga whale, love icy places, while others, like bottlenose dolphins, prefer warmer spots. They can be found near coastlines, out in the deep open ocean, and even in some rivers! It’s like they have homes everywhere in the big blue sea.

What do these ocean dwellers eat? It depends on the type of cetacean! Toothed whales, like the mighty sperm whale, use their teeth to gobble up squid and fish.

Dolphins love to snack on smaller fish and sometimes even squid. Baleen whales, however, are filter feeders. They gulp huge amounts of water and then push it out through their baleen plates, trapping tiny creatures like krill and small fish.

The blue whale, the biggest animal on Earth, eats millions of tiny shrimp called krill every day!

Cetaceans are known for being super smart and social. Dolphins often swim in playful groups called pods, leaping and chattering to each other. Whales can travel thousands of miles every year, migrating to warmer waters to have babies or to find food. Some whales sing long, beautiful songs that can travel for miles underwater. They are truly fascinating creatures of the deep!
