Sharks — the ocean’s most feared and misunderstood predator. Why do they attack? And what’s going wrong in their ecosystem? Surfer, spearfisherman and marine scientist Riley Elliott is fast becoming New Zealand’s most popular shark expert. His fascination with sharks began at South Africa’s famous Oceans Research Great White Shark Station, where he overcame his long-held fear of sharks and learned how to safely freedive with them beyond the cage. Back home in New Zealand, Riley began a PhD in shark biology and soon unravelled some unusual and alarming trends in our ocean ecosystem. Join Riley on his journey to discover what lies beneath the surface.
