Great story this morning about a dolphin “who rescued to stranded whales”:http://www.independent.co.uk/environment/nature/save-the-whales-how-moko-the-dolphin-came-to-the-rescue-of-a-mother-and-her-calf-795025.html in New Zealand. The two “pygmy sperm whales”:http://en.wikipedia.org/wiki/Pygmy_sperm_whale had been discovered by locals, and repeated efforts to free them had come to naught.

"They kept getting disoriented and stranding again," Mr Smith said. "They obviously couldn't find their way back past [the sandbar] to the sea." He was beginning to contemplate killing the pair, to save them from a slow, painful death, when Moko – as local people have named the dolphin – arrived. Moko, who often plays with humans at Mahia, approached the whales and guided them 200 yards along the shoreline and out through a channel into the open sea.
