Several names were suggested for this specimen. The Idaho hunter who killed it, Jim Martell, suggested "polargrizz". The biologists of the Canadian Wildlife Service suggested "grolar" or "pizzly", as well as "nanulak", an elision of the Inuit "nanuk" (polar bear) and "aklak" (grizzly or brown bear). Both "grolar" and "pizzly" were used by the Canadian Broadcasting Corporation in widely distributed stories. Presently, though the mating seasons overlap, the polar bears' season begins slightly earlier than the grizzly bears'. A blog columnist for the Seattle Post-Intelligencer suggested that more hybrids may be seen as global warming progresses and alters normal mating periods. The Canadian Wildlife Service noted that grizzly-polar hybrids born of zoo matings have proven fertile.
