A great white shark in Australia. More than 10% of Australia’s shark species are at risk of extinction, a government report has found. The National Environmental Science Program marine biodiversity hub published the first complete assessment of extinction risk for all Australian sharks, rays and ghost sharks (chimaeras). It found Australia is home to more than a quarter of the world’s cartilaginous fish species, with 182 sharks, 132 rays and 14 chimaeras calling Australian waterways home and that 12%, or 39 species, are facing extinction
