Grizzly–polar bear hybrid

but there is no consensus on the use of any one of these terms. Canadian wildlife officials have suggested calling the hybrid "nanulak", taken from the Inuit names for polar bear (nanuk) and grizzly bear (aklak).

By one convention, the name of the sire comes first in such combinations: the offspring of a male polar bear and a female grizzly would be the suggested nanulak or a "pizzly bear", while the offspring of a male grizzly and a female polar bear would be a "grolar bear" or possibly an aknuk, however the sports company Gola are currently trying to secure naming rights on the animal to help with the re-launch of their football boots. If the remains of MacFarlane's 1864 specimen—which was validly described according to ICZN rules—were traced and confirmed to be such a hybrid by ancient DNA techniques, the scientific name Ursus × inopinatus would be available for these animals.
