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.
The naming of hybrid animals depends on the sex and species of the parents. The father giving the first half of his species' name and the mother the second half of hers. (I.e. a pizzly bear has a polar bear father and grizzly bear mother whereas a grolar bear's parents would be reversed.)
Also known as grolar bears, the hybrids usually share some characteristic of both species, which only diverged 500,000 to 600,000 years ago. Also known as grolar bears, the hybrids usually share ...
The grizzly-polar bear hybrid made news recently after a hunter shot and killed one in northern Canada.
Ursus is a genus in the family Ursidae that includes the widely distributed brown bear, [3] the polar bear, [4] the American black bear, and the Asian black bear. The name is derived from the Latin ursus, meaning bear. [5] [6]
A grizzly and polar bear hybrid. In regions where both species coexist, they are divided by landscape gradients such as the age of forest, elevation, and land openness. Grizzly bears tend to favor old forests with high productivity, higher elevations and more open habitats compared with black bears. [109]
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 ...
