A new species of whale may be cruising the icy cold waters of the Antarctic.
Scientists have recorded a unique whale song, which they can’t identify, in the area.
Evidence for the species is tantalising, rather than strong, as the song could be from one of a few known species of beaked whale.
But it has a structure that doesn’t quite fit any known beaked whales; leaving open the possibility it is from a new species.
Although beaked whales comprise the second-largest family of cetaceans (the group containing whales and dolphins), they are one of the most poorly known groups of all large mammals.
