Zoos have well-thought-out reasoning behind the "Don't Feed Animals" signs. Following that logic, punching a 16-foot trapped shark from an inflatable raft is probably a bad idea. Leave it up to sailors in the Chilean Navy to send mixed signals as they cut free this massive trapped Bluntnose sixgill shark from a tangled fishing line. As a thank you, the powerful fish left a toothy autograph.
Then watch as these Australian beachgoers resisted playful urges when they rescued this suffocating baby humpback whale.
