Sharks have been swimming in Earth’s oceans for over 400 million years, long before the first dinosaurs appeared.​ In that time, our planet has gone through five major mass extinction events, wiping out up to 90% of life each time.​ Yet sharks survived them all.​ ​Their adaptability, varied diets, and ability to thrive in diverse marine environments helped them endure drastic changes in climate, sea levels, and ecosystems. Today, they remain one of the ocean’s most ancient and resilient predator

Sharks are among the oldest living creatures on Earth, existing long before trees appeared and surviving multiple global extinction events. • Sharks first appeared over 400 million years ago. • Trees evolved much later, around 350 million years ago. • Sharks survived at least five mass extinction events. • Their bodies evolved for efficient swimming and energy conservation. • They possess highly advanced sensory systems, including electroreception. • Flexible cartilage skeletons made them adapta
