Shark Why we need to save the world's most misunderstood predator - for Shark Week, Seaspiracy and conservation fans

Something happens to you the first time you dive with sharks...
We have a perennial fascination with sharks. Portrayed in the media and popular culture as killing machines, we are awed by their power and strength. But the shark is so much more - a marvel of the sea, they have evolved over 450 million years into over 500 species, from the bioluminescent kitefin to the tiny dwarf lantern shark, the sociable lemon shark to the blue shark, which can birth up to 100 pups in one litter. Bringing balance to the ocean's ecosystem, our planet is at serious risk when these amazing creatures are threatened.
Paul de Gelder, who lost two limbs in a shark attack during a mission as an elite Australian navy clearance diver, spent time as part of his recovery learning all about sharks. He became so obsessed that, despite what happened to him, he is now an expert and has dedicated his life to helping save them. Shark is his love-letter to these unfairly vilified animals, and his warning to the world about what will happen if we don't look out for them.
