Marine scientists have lassoed an angry shark and removed a large hook from its mouth off Byron Bay in Australia. They had serious concerns for the critically endangered grey nurse shark after it was spotted with a metre-long hook lodged in its mouth. The Sea World Research and Rescue team sent divers in to find the shark earlier this week. The team then threw a rope around its body and waited as the shark thrashed around before tiring itself so it could be brought to the surface. A large PVC pipe was inserted into its mouth.The hook was lodged in jaw cartilage and took 25 minutes to remove
