Sharks Have Existed for Millions of Years

Sharks are some of the oldest creatures on Earth, having existed for more than 400 million years. That’s even longer than the earliest trees, which evolved around 350 million years ago. Sharks have survived through multiple mass extinctions and are considered one of the most successful species in Earth’s history, adapting to different environmental changes over time.

These apex predators have remained relatively unchanged in terms of their basic structure and behavior. Sharks are designed to be highly efficient hunters, with keen senses and a streamlined body perfect for swimming at high speeds. Their long evolutionary history has made them an integral part of marine ecosystems, where they play a vital role in maintaining the balance of ocean life. Shutdown123
