Two skeletons were identified as belonging to the species after a 17-foot whale and her calf beached themselves in New Zealand in 2010. Scientists hope the discovery will provide insights into the species and into ocean ecosystems. In a paper published Tuesday in the journal "Current Biology," researchers from New Zealand and the United States say of their discovery: "For the first time we have a description of the world's rarest and perhaps most enigmatic marine mammal." Conservation workers thought they were Gray's beaked whales and took tissue samples before burying them about nine feet under the sand. Anton van Helden, who manages the marine mammals collection for New Zealand's national museum Te Papa, said it wasn't a straightforward task to find the remains after so long and that the mother's skull, which was buried shallower than the rest of the remains, washed out to sea.
