QUOTE : Hartwell’s subconscious was treated to a lengthy reel of the evolutionary tract of cetaceans – from their early days as hoofed creatures with triangular teeth like wolves, to cat-like creatures, to early variations of the hippopotamus, to bottlenose dolphins and Orca, the ‘killer whale’, which is the largest species of dolphin. The hybrid mammal also had the ability to convert to a smaller aquatic mammal, capable of diving into water and hiding beneath the surface to avoid birds of prey.
