It’s hard to imagine a creature more menacing than a great white shark swimming in the surf, but a giant crocodile comes close.  An estimated 12-foot crocodile was spotted cruising in the swells this past week at Cable Beach in Broome, Western Australia, prompting officials to close the beach to swimmers and surfers for a day.  It’s unclear what lured the reptile into the surf zone, but the unusual sighting generated quite the spectacle.
