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.

“A strong egoism is a protection against disease, but in the last resort we must begin to love in order that we may not fall ill, and must fall ill if, in consequence of frustration, we cannot love.”
