Hook, line and sinking
Grey nurse sharks are protected in Australian waters, yet they continue to be killed through recreational and commercial fishing. In the 1950s and 1960s, vast numbers were slaughtered because of the misconception that they were man-eaters. Their placid nature made them easy targets. But Seal Rocks off New South Wales remains a grey nurse shark hotspot. It's remote and tricky to get to, and Justin had tried unsuccessfully to photograph there on several occasions. But on this day, the visibility was perfect. 'The day was amazing, and I was so excited to be down there,' says Justin - until this shark swam into view, a hook embedded in its jaw. It was his most important shot of the day, highlighting the plight of sharks the world over. At least a hundred million are killed annually mainly for the shark-fin trade.
