Qualia

For 150 years, all that was known of the spade-toothed beaked whale (Mesoplodon traversii) was gleaned from two skull fragments and a jaw bone. Then in December 2010, two individuals - a mother and her male calf - washed up on a New Zealand beach. Although initially misidentified as the more common Gray's beaked whale (M. grayi), DNA analysis revealed their true identity as the world's rarest and most enigmatic marine mammal.
