Dive beneath the surface and discover the truth about one of the ocean’s most misunderstood creatures. In The Hidden World of Sharks, author Calven Hurstin takes listeners on a captivating journey into the lives of nature’s most ancient predators. Far from the villains portrayed in movies, sharks are intelligent, adaptable, and essential to the balance of marine life. With stunning detail and accessible science, this book reveals ten powerful truths that will change how you see the sea forever.

For over 400 million years—long before the age of the dinosaurs—sharks have ruled the oceans. Their story is one of survival, evolution, and mystery. In this beautifully written exploration, you’ll learn why sharks’ skeletons are made of flexible cartilage instead of bone, how they detect electricity in the water, and why some of the biggest sharks on Earth feed only on microscopic plankton. You’ll uncover how their skin, shaped by tiny tooth-like scales called dermal denticles, inspired cutting-edge technology, and why sharks are crucial to keeping our oceans healthy.

Each chapter dives deep into a different aspect of shark biology and behavior:

1. Sharks Are Older Than the Dinosaurs – Explore the incredible evolutionary history that has kept sharks thriving for hundreds of millions of years.
2. They Aren’t Bony Fish – They Have Cartilage Skeletons – Learn how this unique design gives sharks speed, flexibility, and silent grace.
3. There’s a Huge Variety of Shark Species – Meet over 500 species, from gentle whale sharks to glowing deep-sea hunters.
4. Sharks Have an Incredible Sense of Smell – Discover how they detect a single drop of scent in an ocean of water.
5. They Can Detect Electricity – Understand the “sixth sense” that allows sharks to locate hidden prey.
6. Not All Sharks Need to Keep Swimming to Breathe – Find out which species rest on the seabed and how they manage to breathe still.
7. Their Skin Feels Like Sandpaper – Examine how their skin reduces drag and helps them move silently through the sea.
8. Sharks Replace Their Teeth Throughout Their Lives – Learn why some sharks can grow and lose thousands of teeth in a lifetime.
9. The Biggest Sharks Eat Tiny Things – See how the ocean’s giants survive on the smallest meals.
10. Sharks Play a Crucial Role in Keeping Oceans Healthy – Discover how these apex predators balance marine ecosystems and protect biodiversity.

Rich with real science, awe-inspiring facts, and a strong message of conservation, The Hidden World of Sharks celebrates these remarkable creatures as guardians of the sea, not monsters. From the smallest lanternshark to the massive whale shark, every species tells a story of resilience and adaptation.

Hurstin’s engaging writing style brings the underwater world to life—blending education with wonder. Listeners of all ages will gain a deeper understanding of why sharks matter, how they connect to the health of the entire planet, and what we can do to protect them from extinction.

Perfect for ocean lovers, divers, wildlife enthusiasts, and curious minds, this book invites you to trade fear for fascination. It’s time to look past the myths and meet the real sharks—the ancient navigators, the silent hunters, the caretakers of the deep.

Discover the truth. Protect the future.
The Hidden World of Sharks will make you see the ocean—and its most misunderstood inhabitants—in an entirely new light.
