 Off Queensland, Australia, the tawny nurse shark is valued by big-game anglers.When hooked, large individuals are tenacious opponents and are difficult to subdue due to their habit of spinning.They are also capable of spitting a powerful jet of water into the faces of their captors, making grunting noises in between jets (making the tawny shark one of the few species of sharks to produce a noise);whether this is a deliberate defensive behavior is uncertain.
