Scientists have discovered a new species of ghost shark that lives in deep ocean waters near Australia and New Zealand.

If you’re thinking of going down the unconventional route for this year’s Halloween costume, we’ve got just the inspiration for you: a brand-new species of chimaera, better known as a ghost shark or spookfish.

A new species of ghost shark or “spookfish” was discovered lurking in the deep, dark waters off the coast of New Zealand. The Australasian narrow-nosed spookfish ( Harriotta avia) is exclusive to New Zealand and Australia’s waters and is part of a group of cartilaginous fish that are closely related to rays and sharks called chimaeras.
