Skulls of New Species (IMAGE)
Caption
The neotype skulls for Bigg's killer whale, Orcinus rectipinnus (left), and the resident killer whale, Orcinus ater (right). The Bigg's killer whale skull is more robust and has a wider rostrum (beak), which are presumably adaptations for feeding on larger prey such as marine mammals.
