Moko, a bottlenose dolphin in New Zealand who likes to swim with the locals, rescued a pair of pygmy sperm whales that were stranded and dying on a sandbar.
"They kept getting disorientated and stranding again," said Smith, who was among the rescuers. "They obviously couldn't find their way back past (the sandbar) to the sea."
Along came Moko, who approached the whales and led them 200 meters (yards) along the beach and through a channel out to the open sea.
"Moko just came flying through the water and pushed in between us and the whales," Juanita Symes, another rescuer, told The Associated Press. "She got them to head toward the hill, where the channel is. It was an amazing experience. The best day of my life."
