Shark appears from the darkness to sniff diver's camera

Nurse sharks are friendly and curious creatures, like puppy dogs of the deep. But when they suddenly appear out of the darkness at night, it can be a hair raising experience. In the few seconds it took to recognize that this large beast was not a man eater, this diver had some heart-pounding excitement. The shark was likely just curious about the diver or wanted a free meal. Or maybe this is how sharks with a sense of humor prank people. This shark disappeared as quickly as he appeared, possibly off to prank another diver.
