@truewild1: We know these animals exist. We have never seen them alive. The Spade-Toothed Whale is the rarest large animal on Earth — known only from 3 strandings, never photographed, never seen by any human being alive or dead. The Giant Squid existed in the stomachs of sperm whales for centuries before anyone believed it was real — and was only photographed alive for the first time in 2004. In the Indian Ocean, repeated acoustic signals from the deep confirmed the existence of Omura's Whale for 40 years — and for 40 years not a single living individual was ever seen. And in the Ross Sea, repeated acoustic signals do not match any known whale or dolphin species. Scientists do not know what is making them. Which mystery do you most want solved?
