3. The Evolution of Whales
Around 50 million years ago, whales made the transition from land to sea, becoming the majestic marine mammals we know today. This evolutionary shift allowed them to take advantage of the vast resources of the ocean, such as an abundance of food and protection from predators. Since then, whales have adapted to their aquatic environment, developing specialized features like blowholes, streamlined bodies, and flippers. They have also evolved a variety of behaviors, such as breaching, spyhopping, and lobtailing, that help them to survive and thrive in the depths of the ocean.

4. The Incredible Amount of Food Whales Eat
Whales are some of the largest creatures on the planet, and they need to consume a staggering amount of food to sustain their size. On average, whales need to eat between 50-150 kilograms of meat every day in order to stay healthy and active. That's the equivalent of about 110-330 pounds of food per day! To put that into perspective, that's like a human eating between 8-20 large pizzas every day.

To put this into perspective, a ton of food is equivalent to about 2,000 pounds of krill, small fish, and other marine life. This is why humpback whales are often seen in large groups, as they need to consume such a large amount of food to sustain their massive size.

10. How Whales Breathe
Whales are fascinating creatures, and one of the most interesting facts about them is that they can't breathe through their mouths. This is because the mouth of a whale is connected directly to its stomach, meaning that air cannot pass through it. This is why whales must come to the surface of the water to breathe, as they have blowholes on the top of their heads which allow them to take in air.
