✨ Highlights📊 Transcript
Kodiak bears are the largest subspecies of Brown bears, with males growing up to 10 feet tall and weighing from 800 to 1,400 pounds.
00:01
Females are smaller, weighing about 500 to 700 pounds.
Kodiak bears have brown fur, with lighter coloring on their face compared to the rest of their body.
They have powerful teeth and jaws, and bulky bodies to store fat.
Kodiak bears have sharp and long claws, while polar bears have large feet and strong claws for traction and hunting.
02:17
Kodiak bears have great sense of hearing and smell to compensate for their poor eyesight.
Male polar bears are about twice the size of females and can weigh up to 2209 pounds.
Polar bears are adapted to life in the Arctic cold with small ears, tails, and short legs.
Kodiak bears are found exclusively in the Kodiak Archipelago in southwestern Alaska, while polar bears live in subpolar climates near the Arctic Circle.
Kodiak bears inhabit more urban areas like garbage dumps, while polar bears primarily live in the Arctic Circle and depend on sea ice for hunting seals.
04:31
Kodiak bears are omnivorous and feed on a variety of foods, including vegetation, salmon, berries, seaweed, and invertebrates.
Polar bears are carnivores and their primary food source is seals, specifically seal blubber.
Polar bears are excellent swimmers and can travel long distances between shore and sea ice, but storms during these swims can be dangerous for them, especially for cubs.
Kodiak bears are solitary and use different noises and body language to determine dominance, while polar bears tend to live solitary lives except when mating or when attracted to a food source.
06:49
High-calorie meals help bears build up fat reserves and maintain body temperature.
Kodiak bears are a subspecies of the brown bear and polar bears are terrified of grizzlies.
Polar bears near Churchill on the coast of Hudson Bay are known to play with chained sled dogs without killing them.
In a fight between a Kodiak bear and a polar bear, the Kodiak bear would likely win due to its larger size, stronger forelimbs, and thicker claws.
09:01
Kodiak bears are almost identical to grizzlies but much bigger and proportionally stronger.
Kodiak bears have the strongest forelimbs of any terrestrial predator, giving them a physical advantage.
Kodiak claws are longer and thicker than polar bear claws, allowing them to inflict more damage.
The Kodiak bear's trump card is its stamina, as polar bears quickly overheat on land due to their thick fur and layers of fat.
00:01Kodiak Bear vs Polar Bear
00:05Who would win a fight between these two giant bears?
00:10A fight between a polar bear and a Kodiak bear is a human fancy that can never happen in nature.
00:17Polar bears are the kings of Arctic ice sheets,
00:20while Kodiak bears have been isolated to the Kodiak Archipelago for 12,000 years.
00:28Their paths never cross.
00:31Polar bear and Kodiak bear are two different species not only in their diet, habitat,
00:38and distribution but also in their behavior. The only common trait between the two predators is their size.
00:47They are almost of the same size.
00:50Either way both animals have long fascinated biologists
00:55for their super strength and ability to take down prey nearly the size of their own.
01:03Size and Description
01:06Kodiak bears are the largest subspecies of the Brown bears which has given them a reputation in the wild
01:13a being a force to reckon with.
01:16The males can grow to be about 10 feet tall (3 m) and weigh from 800 to 1,400 pounds (362 to 635 kg).
01:30The females are smaller than that but still a very large size overall.
01:35They can be about 500 to 700 pounds (226 to 317 kg).
01:46This particular bear is brown in color.
01:49The overall coloring on the face is going to be lighter than what is found on the rest of the body.
01:56This is the distinct way to tell them apart from the Grizzly Bear.
02:01The enormous head of the Kodiak bear is worth taking a close look at.
02:06They also have powerful teeth and jaws that can tear through prey very quickly.
02:13They have bulky bodies so that they can store up fat.
02:17The claws of a Kodiak bear are very sharp and long.
02:21They don’t have very good eyesight but them make up for it with their great sense of hearing and smell.
02:29Polar bears are extremely large animals.
02:33While both sexes look alike, males are about twice the size of females.
02:39An adult male ranges from 7.9 to 9.8 feet (2.4 - 3 m) in length and weighs 770 to 1500 lbs (350 - 680 kg).
02:50The largest male polar bear on record weighed 2209 pounds (1002 kg).
02:58Females measure 5.9 to 7.9 feet (1.8 - 2.4 m) in length and weigh between 330 to 550 pounds (149 - 249 kg).
03:08However, females can double their weight when pregnant.
03:12With their small ears and tails and short legs, polar bears are adapted to life in the Arctic cold.
03:20Their large feet help to help distribute weight on ice and snow.
03:25Strong, sharp claws are also important for gaining traction, for digging through ice, and for killing prey.
03:35Range and Habitat
03:38The Kodiak bear subspecies ranges only in the Kodiak Archipelago in southwestern Alaska.
03:45The islands they live on include Kodiak, Sitkalidak, Afognak, Uganik, Shuyak, Raspberry,
03:53and some adjacent islands.
03:56This means the bears have a range of approximately 5,000 square miles of islands.
04:03These large mammals live exclusively in subpolar climates, just below the Arctic Circle.
04:10The archipelago is in close proximity to the ocean, which provides a variety of food sources.
04:17On the islands, habitats can range from dense forest to icy mountains.
04:23Some islands also have flat tundra, hills, streams, and lakes, all of which bears also utilize.
04:31In some instances, Kodiak bears inhabit more urban areas, particularly garbage dumps.
04:39Most polar bears occur north of the Arctic Circle to the North Pole.
04:44There are some populations south of the Arctic Circle in the Hudson Bay of Manitoba, Canada.
04:51Polar bears live in Alaska, Canada, Russia, Greenland, and some northern islands owned by Norway,
04:59such as Svalbard.
05:01Polar bears depend on the sea ice, which forms above the open waters where their seal prey lives.
05:08They will spend time on land when sea ice is not available.
05:13Polar bears are excellent swimmers, and they travel long distances between shore and the sea ice if necessary.
05:20However, if a storm kicks up during these increasingly long swims, they can drown.
05:27These long swims and storms are also often difficult for cubs.
05:32During periods of ice breakup, polar bears frequently swim between floating ice islands.
05:41Diet
05:43Kodiak bears are omnivorous, eating a variety of foods.
05:48The bear's large size is mainly due to the abundance of food readily available to them on Kodiak Island.
05:56In general, Kodiak bears are solitary creatures, though they often feed in large groups when food is plentiful.
06:04After hibernation, they feed on vegetation and animals that died the past winter.
06:11Starting in May, the bears feast on a salmon run that lasts into October.
06:17Fish are an important part of their diet.
06:20However, Kodiak bears will more often spend their time feeding on vegetation
06:25rather than put in the time and effort required to kill animals.
06:30They also feed on several types of berries, seaweed, and invertebrates.
06:36The polar bear's primary food source is seals.
06:40Their diet of meat makes them carnivores. If the food supply is plentiful, they will only eat seal blubber.
06:49This high-calorie meal helps the bears build up fat reserves,
06:54which keep polar bears healthy between feedings and help maintain their body temperature.
07:00If seal hunting isn't going well, polar bears will also eat anything they can find, such as fish, eggs, vegetation,
07:09reindeer, rodents, birds, berries and human garbage.
07:15Behavior
07:17For the most part, Kodiak bears are solitary.
07:21They will live in areas with other bears close by, and even feed on the same food sources,
07:27but they do not remain in social groups.
07:30Bears will determine dominance using different noises and body language to avoid fights.
07:37As with other bear species, behavior varies based upon proximity to humans.
07:43Bears that live in areas where human population is higher will be mostly nocturnal,
07:49while bears in more desolate areas are active during the day.
07:55Polar bears tend to live solitary lives except when mating,
07:59when a female raising her cubs forms a family group,
08:03or when many bears are attracted to a food source like a beached whale.
08:08Young polar bears spending the summer ashore on the Hudson Bay coast will frequently play with each other,
08:15most commonly with their siblings.
08:18Polar bears near Churchill on the coast of Hudson Bay
08:22are even known to play with chained sled dogs without killing them, which they could easily do.
08:29Now it’s time to find out, who will win a fight between these two bears?
08:36Kodiak Bear or Polar Bear?
08:39There is, however, little doubt how it would play out,
08:43because Kodiak bears are a subspecies of the brown bear.
08:48Polar bears are terrified of grizzlies to whom they always give up their kill or carrion.
08:55If a 1,500 pound polar bear flees from an 800 pound grizzly,
09:01it sure will not stay to fight a 1,200 pound Kodiak bear, which is just about identical to a grizzly,
09:08except much bigger and proportionally stronger.
09:13At first glance it seems that polar bears should dominate brown bears, because they are bigger.
09:19A deeper dive into the facts sheds more light on the question.
09:23A kodiak may not have much of a physical disadvantage to a polar bear for the following reasons:
09:30Kodiak bears have the strongest forelimbs of any terrestrial predator,
09:35and this is due to the humps over their backs are part of the muscles that operate these powerful tools.
09:43Polar bear claws are primarily three inch cleats for good footing on ice.
09:49Kodiak claws are 4 to 5 inches long and much thicker.
09:54They are effortlessly used to dig huge holes in the ground,
09:58and can inflict far more damage than polar bear claws.
10:03Grizzlies match polar bears in the size of their canines and in bite force (1,200 psi), but are more robustly built.
10:14Perhaps all this is not enough to overcome the strength that accrues to sheer body mass,
10:20but there is one final factor that is the Kodiak bear’s trump card: stamina.
10:28Polar bears have great stamina swimming in icy waters, but on land, even in the most frigid places,
10:35they quickly overheat, due to their superb insulation conferred by their thick fur and layers of fat.
10:44If the contest between polar bear and Kodiak bear could occur,
10:48the polar bear would flee even more urgently than it does from grizzlies.
10:53The Kodiak bear is almost the same size as the polar bear, stronger, and has far better stamina on land.
11:02The polar bear cannot afford this losing battle, therefore would retreat to save itself.
