Description
Every year on National Dolphin Day – April 14, you get a reason to smile just thinking about these playful marine animals. Whether you’ve seen one leap over a wave or heard their chirpy squeaks, dolphins have probably won your heart already.
History
Long before dolphins were swimming gracefully through the oceans, their ancient ancestors were actually walking around on land. Yep, you read that right — about 50 million years ago, certain four-legged mammals began spending more time in the water than on land. Over generations, these curious creatures adapted to life in the ocean, and their bodies started to change dramatically.
These early swimmers eventually lost the ability to walk on land and became fully aquatic mammals. One of the best-known examples of these early ocean pioneers is the Dorudon. Like dolphins, Dorudons were sleek, streamlined, and perfectly suited for ocean life — but they looked a bit more prehistoric and less smiley.
Around 30 million years ago, a new type of toothed whale called the Squalodon appeared. They weren't direct ancestors of modern dolphins, but they were definitely on a related evolutionary path. Squalodons had long jaws full of sharp teeth, and more importantly, they had something very cool in common with dolphins: echolocation.
Echolocation is like a built-in sonar system — an amazing ability that lets dolphins “see” through sound, especially in deep or murky waters. The fact that squalodons were already using echolocation shows how long this natural skill has been around!
