Dolphins' Protection
There are documented instances of dolphins protecting humans from shark attacks, such as one attack on a surfer in northern California in August 2007 and one off the coast of New Zealand in 2004. There is no accepted explanation for this behavior; as mentioned in the Journal of Zoology, "The importance of interactions between sharks and cetaceans has been a subject of much conjecture, but few studies have addressed these interactions". In some cases, sharks have been seen attacking, or trying to attack dolphins. The presence of porpoises does not indicate the absence of sharks as both eat the same food.

“As Jerome expanded, its chances for the title, “the toughest little town in the West,” increased and when it was incorporated in 1899 the citizens were able to support the claim by pointing to the number of thick stone shutters on the fronts of all saloons, gambling halls, and other places of business for protection against gunfire.”
