What if I told you the BIGGEST animal that has EVER lived on Earth swam in our oceans RIGHT NOW?
Get ready to shrink down to size because today on History's Not Boring, we're talking about whales! These amazing creatures are HUGE, warm-blooded mammals that live in the sea, but they need to come up for air just like us. There are about 79 to 84 different species of whale, and they come in all shapes and sizes! From the giant Blue Whale to the smaller, speedy ones, they are true ocean explorers. We’re going to learn what makes them so special for kids ages 4-12 to discover!

"Wow, Finn! I heard the Blue Whale's heart is as big as a Volkswagen Bug car! That’s way bigger than my bike! It just goes to show how much history is packed into nature too!"
What are the Two Main Kinds of Whales?
Even though they all swim in the ocean, scientists put whales into two main groups based on how they eat. It’s like sorting toys into 'block' toys and 'puzzle' toys!
The first group is called Baleen Whales. They are the filter-feeders! Instead of teeth, they have long, hard strips in their mouths called baleen that work like a giant kitchen strainer. They gulp in huge amounts of water filled with tiny snacks like krill—those tiny, shrimp-like animals—and then push the water out, trapping the food inside!
The second group is the Toothed Whales. Think of dolphins and orcas (killer whales) in this group! They have sharp teeth and hunt for bigger food like fish, squid, and sometimes even small sea mammals. They also have a super cool trick called sonar, which is like a natural radar system!
Mind-Blowing Fact!
Whales don't sleep like you and me! If they fell into a deep sleep, they would drown because they need to *remember* to swim up to the surface to breathe. Instead, they only shut down half of their brain at a time to rest!
How Big is the Blue Whale, Really?
The Blue Whale is the champion! It’s the largest animal known to have ever existed—even bigger than the biggest dinosaurs we know about!
These ocean giants can grow up to 100 feet long! That is longer than three school buses lined up end-to-end! Talk about a long trip to school!
They are also super heavy. An adult Blue Whale can weigh up to 333,000 pounds! To put that in perspective, that’s about the weight of 25 grown-up elephants!

How Do Whales Talk to Each Other?
Whales have amazing ways to communicate across the giant ocean. It's a whole underwater language!
Some baleen whales, especially Humpbacks, are famous for their beautiful, long, and complicated whale songs.
These songs can be super loud and can travel for many miles underwater, which helps them find friends or mates. Toothed whales, on the other hand, use sharp clicks and sounds for echolocation—it’s like sending out a sound and listening for the echo to map out what’s around them, even in dark water!
Whale Babes: The Calves
A baby whale is called a calf, and they are already big babies! A newborn Humpback calf can weigh 1 to 2 tons and be about 10 to 15 feet long.
Momma whales are super protective and stick close to their calves. The babies drink lots of milk from their moms—some drink about 50 gallons of milk a day when they are growing fast!
💡 Did You Know?
The very oldest whale scientists have found is the Bowhead Whale! Some of them have been estimated to live for over 200 years! That means they might have been swimming around before your great-great-grandparents were even born!

Who Helps Whales Stay Safe?
Even though whales are huge, they need our help to stay safe in the ocean today. Humans have learned a lot about protecting these gentle giants.
For a long time, whales were hunted during the whaling era, which almost drove some species like the Blue Whale to extinction. But now, many countries work together to protect them!
- Pod Power: Most whales travel and live in groups called pods. These pods often have about two to thirty whales, but sometimes they join up for long trips called migrations!
- Super Swimmers: Whales use their tails, called flukes, to push through the water with an up-and-down motion, which helps them zoom up to 30 miles per hour!
- Singing for Miles: The songs of some whales can be heard from miles away underwater, making them some of the loudest communicators in the animal kingdom!
- Big Travel: Some whales, like Humpbacks, make one of the longest journeys of any mammal, swimming up to 5,000 miles every year!
So, whether it’s the massive Blue Whale or the singing Humpback, whales are true wonders of history, nature, and science all rolled into one amazing package. Keep listening to History’s Not Boring to learn about more incredible things on our planet and throughout time!
