Megalodon is the T. rex of the prehistoric shark world—it might have looked like a Great White, only way, way bigger, and it’s everybody’s favorite. It’s had its moment in the sun, even starring in a fake Shark Week documentary saying that it’d been found in modern waters (don’t worry—megalodon has been extinct for millions of years). But The Field Museum is home to some really bizarre sharks that lived millions of years before dinosaurs were even a twinkle in the universe’s eye.

Sharks seem to have it all figured out, evolution-wise. Fossils of prehistoric sharks go all the way back to 450 million years ago, and sharks like the ones we know today emerged about 200 million years ago. This means that they survived the mass extinction that took out the dinosaurs and lived long before early human ancestors evolved less than two million years ago. So, what makes a shark a shark? Here are just a few of its unique physical features: Read more about What Makes a Shark a Shark?

Diaphonization -- otherwise known as clearing and staining -- is one of the most photogenic preparation methods used by research scientists. It's beautiful, but is it practical? We interviewed Dr. Caleb McMahan, Collection Manager of Fishes, on how he uses this technique to answer questions about the evolution of fish! Big thanks to Caleb for taking the time to share his work with us, and to Alan Resetar for lending the reptile and amphibian specimens!... as well as the extra light table because ours broke right before filming. :( Read more about Clearing and Staining Fishes
Wherein Isobel and Maria show us the ropes -- or nets -- for surveying fishes in the Amazon. The distribution of fish in tropical river systems is important to understanding how animals move around these waterways. Where there are big fish -- like the electric eel -- we know there must be an ample supply of prey species, too!
