It takes a village to deliver a whale calf.
The birth of a sperm whale (Physeter macrocephalus) has been captured on camera in more intimate detail than ever before, researchers report March 26 in Science. The female sperm whale giving birth was aided by 10 other sperm whales, almost all female, but not all kin. The footage makes clear that, like humans, sperm whales benefit from cooperation, so much so that the instinct to help transcends family barriers.
