Toggle navigation. Grolar bear Facts Grolar bear is a hybrid species of bear, created by interbreeding of grizzly bear and polar bear. As a result of global climate changes and melting of the ice on the polar caps, geographic distribution of grizzly bears and polar bears starts to overlap. Polar bears and grizzly bears often encounter each other on the boarder of tundra and sea on the Alaska and in the northern parts of Canada today. When they meet each other during the mating season, two species interbreed and create hybrids known as grolar bears or pizzly bears. First grolar bear has been observed in the wild in

This "grolar" bear was shot by year-old Didji Ishalook earlier in Photo via Didji Ishalook's Facebook page. Each hybrid draws its name from its paternal ancestory; the former is the result of a male grizzly bear mating with a female polar bear, while the latter is a male polar mating with a female griz. The hybrids are fairly recent discoveries in the cold Canadian North. Scientists point to climate change as the catalyst for these previously unheard-of progeny, with warming temperatures allowing grizzly bears to push farther north into the Arctic reaches. Polar bears are also marching northward, but when the two overlap the results are striking. Photo via iStock. Adult male polar bears weigh from to 1, pounds, with a total length of nine feet or more. They stand four feet at the shoulder and have a longer, slenderer skull and neck than a grizzly, with no shoulder hump present. They stand about three feet at the shoulder but have the unmistakable hump that distinguishs them from black bears when the latter has a brown-phase coat.

So far, eight polar bear-grizzly hybrids have been confirmed in the grolar bear size in the Canadian Arctic. Is this interbreeding possibly even a response of the bears to climate change?

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 , 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 Territories , on Banks Island in the Canadian Arctic. The number of confirmed hybrids has since risen to eight, all of them descending from the same female polar bear. Possible wild-bred polar bear — grizzly bear hybrids have been reported and shot in the past, but DNA tests were not available to verify the bears' ancestry. Genetic analysis has revealed multiple instances of introgressive hybridization between bear species, [4] [5] [6] including introgression of polar bear DNA into brown bears during the Pleistocene "grizzly bear" is a local common name for Ursus arctos whereas "brown bear" is used internationally and in science to refer to the species as a whole.

Sometimes when you reach max level, you stop levelling. They needed to take things one step further and team up with the most iconic and terrifying animal in North America; an animal so scary its scientific name is horribilis. As the polar regions get warmer, brown bears can tolerate higher latitudes. Conversely, the shrinking habitat of polar bears is creating a refugee crisis as the great beasts descend to lower latitudes in search of new territories. In the first wild evidence of a grolar bear hybrid was confirmed with DNA testing. Subsequently the number of confirmed hybrids in the wild is thought to be around 8, although others have also been reported, yet not confirmed. They physical traits of hybrids appear to be generally intermediate between their parents. Hybrids tend to have smaller bodies than polar bears, but larger than grizzlies. They can have creamy fur typical of polar bears, but with a humped back, long claws and brown patches around its eyes and feet, which are more typical of grizzly bears. Like both parents, grolar bears are opportunistic apex predators that are capable of hunting large prey and diet largely on meat.

A brown bear—polar bear hybrid. In , Andrew Derocher was in the field with an Inuit hunter when a message crackled over the CB radio: A strange-looking bear had been shot a few miles away. With a dingy white coat and scattered tufts of brown fur, it resembled a dirty version of the Arctic predator. It had dark rings encircling its eyes like sunglasses, and its claws were a few inches too long. Derocher, a professor of ecology at the University of Alberta, would later learn that the bear was the first known grizzly bear—polar bear hybrid found in the wild. Since then a handful of similar hybrids—nicknamed grolar bears or pizzly bears—have turned up. While the bears are still rare, says Larisa DeSantis, an associate professor of biological sciences at Vanderbilt University, the new hybrids may become more common as the Arctic ice melts, depriving polar bears of their customary hunting grounds on ice floes. This forces them to hunt on land, where they increasingly encounter northerly-ranging grizzlies. In fact, it gives her hope for the future.

They stand about three feet at the shoulder but have the unmistakable hump that distinguishs them from black bears when the latter has a brown-phase coat. Polar bears are perfectly adapted to life in the Arctic. Photo by Dirk Freder via iStock. Follow Us. Retrieved January 29, You may also like. The later name has been suggested as the final, catch-all designation by Canadian wildlife officials. Want to find out if bears can climb trees? March 14, Climate change and the melting of Arctic ice have led to greater opportunities for these two bear species to come into contact, increasing the chances of interbreeding. Polar bears usually have small molars that are worn down due to their primary diet of seal blubber. The grolar bear is an intriguing example of hybridization in the animal kingdom, showcasing the blend of characteristics from two iconic ursine species. Climate change plays a significant role in the habitats of polar bears and grizzlies, leading to the melting of sea ice and the alteration of territories. The hybrid was created because of global warming.

The animal is certainly weird, scientists say, but he's not necessarily a symbol of global warming or anything else. The animal confirmed last week to be half polar bear , half grizzly bear is certainly weird, scientists say, but he's not necessarily a symbol of global warming or anything else.

Nunatsiaq News. Find out in this article I wrote. After the first pizzly was identified in , the next pizzly bear found was a suspected polar bear killed in They stand four feet at the shoulder and have a longer, slenderer skull and neck than a grizzly, with no shoulder hump present. Four years later, an Inuvaluit hunter in northwestern Canada shot another hybrid bear. Bryan Harding. It is clumsy on the ice due to long claws. Canadian wildlife officials have suggested calling the hybrid " nanulak ", taken from the Inuit names for polar bear nanuk and grizzly bear aklak. They stand about three feet at the shoulder but have the unmistakable hump that distinguishs them from black bears when the latter has a brown-phase coat. Elephant hybrid. There are multiple names for this new bear such as Pizzly, Grolar bear, and Polizzly, and even Nanulak, but they have not decided on a solid name yet. When polar bears and grizzlies meet, the encounter is usually aggressive.
