A grizzly–polar-bear-hybrid (also named grolar bear, pizzly bear, zebra bear, [1] [2] grizzlar, or nanulak) is a rare ursid hybrid that has occurred both in captivity and in the wild. In 2006, the occurrence of this hybrid in nature was confirmed by testing the DNA of a unique-looking bear who had been shot near Sachs Harbour , Northwest ...
Possible hybridisation between different species of bear. An ursid hybrid is an animal with parents from two different species or subspecies of the bear family (Ursidae).Species and subspecies of bear known to have produced offspring with another bear species or subspecies include American black bears, grizzly bears, and polar bears, all of which are members of the genus Ursus.
A hybrid between grizzly bears and polar bears has also been recorded. Known commonly as a pizzly, prizzly, or grolar bear, the official name is simply " grizzly–polar bear hybrid ". Fossils
The grizzly-polar bear hybrid made news recently after a hunter shot and killed one in northern Canada.
The bear scientists shot in the Canadian arctic in 2016 was a biological mystery. It looked like a grizzly bear, complete with long claws and a prominent snout, but most of its fur was white.
Ursid hybrids, such as the grizzly-polar bear hybrid, occur between all species except for the giant panda. Suborder Feliformia. Family Felidae (see Felid hybrids); various other wild cat crosses are known involving the lynx, bobcat, leopard, serval, etc. Pumapard, a hybrid between a cougar and a leopard. Subfamily Felinae
Bear habitats are generally forests, though some species can be found in grassland and savana regions, and the polar bear lives in arctic and aquatic habitats. Most bears are 1.2–2 m (4–7 ft) long, plus a 3–20 cm (1–8 in) tail, though the polar bear is 2.2–2.44 m (7–8 ft) long, and some subspecies of brown bear can be up to 2.8 m (9 ...
For a hybrid form to persist, it must be able to exploit the available resources better than either parent species, which, in most cases, it will have to compete with.For example: while grizzly bears and polar bears may be able to mate and produce offspring, a grizzly–polar bear hybrid is apparently less- suited in either of the parents' ecological niches than the original parent species ...
