NatGeo - Newly described as its own species, the Ziebell's handfish typically has yellow fins, as seen above in a file photo, but the species can also appear with a mottled purplish coloration. Ziebell's handfish is found only in small, isolated populations off Tasmania and is listed as vulnerable in Australia.

Today all handfish are found only around southeastern Australia. But about 50 million years ago the animals likely inhabited regions around the world, the CSIRO scientists note. Fossils of the curious creatures have been discovered in the Mediterranean, for example.
