Sharks are not creatures of a single ocean. They move through every sea on Earth—crossing borders, shaping ecosystems, and connecting continents in ways few other animals can. Yet despite their global presence, sharks are often misunderstood, feared, or forgotten entirely. Sharks Around the World is a sweeping, science-based exploration of sharks across the planet’s oceans—from tropical reefs and island chains to polar waters and the deep sea. Blending marine biology, geography, cultural history, and conservation science, this book reveals how sharks live, migrate, and survive in vastly different environments—and why their future depends on global cooperation rather than isolated solutions. Through detailed regional chapters, readers travel across: North and South America - Europe, Africa, and the Middle East - South and Southeast Asia - East Asia and the Indo-Pacific - Australia, the Pacific Islands, and the planet’s most extreme seas Each chapter examines how environment shapes shark behavior, how human cultures have interacted with sharks over time, and how modern pressures—from industrial fishing to climate change—are altering life beneath the surface. The book also highlights conservation successes from around the world, proving that recovery is possible when protection is real, enforced, and culturally informed. Written for ocean lovers, conservationists, students, educators, and anyone seeking a deeper understanding of sharks beyond fear-driven myths, Sharks Around the World reframes these ancient animals not as threats, but as essential guardians of ocean health. This is not a book about isolated species or sensational encounters. It is a global story—one that challenges how we see the ocean, how we value life within it, and how humanity chooses to coexist with the world’s oldest predators.
