The Pacific Ocean. World of Giants The 'Explore the World Together' Series. Atokhon Ghaniev

      "They dive deep to hunt for creatures like the giant squid," Zaki said. "Sperm whales are some of the deepest diving mammals in the world. They can reach depths of over 7,000 feet, and they rely on echolocation to navigate and find their prey in the dark waters."

      "Echolocation?" Amin repeated.

      "Yes," Zaki continued. "Sperm whales produce clicking sounds, which travel through the water. When these sounds bounce off objects, the whales can 'see' their surroundings through the returning echoes. It’s similar to how bats navigate in the dark."

      Suddenly, they felt a rumble in the water. A large shadow passed overhead, and before they knew it, a sperm whale appeared, gliding through the deep waters like a silent submarine. It was an awe-inspiring sight, and Amin and Lola could hardly believe they were witnessing such a majestic creature in its natural habitat.

      The whale dove even deeper, disappearing into the shadows.

      "These giants of the ocean have adapted to survive in some of the harshest conditions on Earth," Zaki said. "Their ability to thrive in such deep and cold waters shows just how remarkable life in the ocean can be."
