Giant Nurse Shark!
The above picture shows a diver posing beside a truly monstrous tawny nurse
shark (Nebrius ferrugineus) at Marion Reef in
Australia, an oceanic atoll 500 km (310 miles) off Townsville, Queensland.
The maximum size for the tawny nurse shark is 14 ft.
The shark in the above photo appears to be much longer than that, but this
is an optical illusion caused by the diver being further away from the
camera than the shark. The shark is actually about 13-14 ft long: still a
monster by anyone's book!
