We hear about the loss of species all the time, but we might have gained a new species to learn about...well, sort of.
Researchers with the National Oceanic Atmospheric Administration have long been searching for this species dubbed 'Type D killer whale,' which are actually dolphins.
On a recent trip off the coast of Chile in January, researchers think they may have spotted them.
DNA tests from samples they obtained will confirm if indeed this is a new, distinct species.
They were only first known in 1955 when a pod of them became stranded near New Zealand, but spotting them ever since has been next to impossible.
Why are they so elusive?
They live in open ocean in a region known as the 'sub-antarctic'- one of the most inhospitable and difficult to reach places on earth.
