American Black Bear vs Bull Shark in shallow water (4ft or ~122cm deep)... *Even in water only 3 feet deep I would wager on the bull shark.

I am not really sure on this one; if the bear got a proper hold on the bull shark, he would be able to suffocate it while biting into its head. I would have to see some American alligator - American black bear interactions before being fully confident in favour of the shark.

Alaska Peninsula Brown Bear vs Salmon Shark in shallow water (4ft or ~122cm deep)I know matchups like this have sparked some controversy, however, I think the bear would have the shark for breakfast to be honest; he could easily secure it with his clutches and finish it off with a devastating bite. This shark is way too small to resist the brute force of a large brown bear, I'd even favour him in deeper water.

I would love to think so 'Taker, but sharks are fast. They have teeth like razor-blades. The "scales" are actually just like their teeth. The bear rubs the shark the wrong way, his paws will be bleeding. My neighbor once caught a bull shark ( 6 feet long ) and brought it in. At his house ( next door ) he was trying to cut the shark's jaws out for a "trophy". He kept running back and forth from inside his house and back. I had to ask.... he kept having to sharpen his knife. He finally gave up on that idea. ( I believe someone helped him with some other method ). My point being... the shark's hide is like super-tough. One weakness the shark has; he cannot twist-and-turn like a reptile. This is why alligators and crocodiles can usually best a shark. The shark must male a wide circle to return to an adversary or prey. ( or so I've read ).

I just can't see it happening here, I am sorry; if the bear got hold of that shark who is ~ less than half his own weight, he would be able to crush it almost instantly in my opinion. A shark isn't heavily armored like a crocodile; yes, it has a tough skin, however, that won't stop an 800lbs+ brown bear's jaws from tearing into it without any severe issues.

I agree if it's a smaller Shark say 6 ft, but a larger shark say for instance a Large Tiger shark or Great white, not so sure the Bear even a 1000 lb giant will come away unscathed in 4 ft of water. I say unscathed in that he may not be killed but will come away with some nasty wounds. In deep water all bets are off and the now the bear is completely out of his element and sharks just T off on him.

There is a rare incident of a polar bear attacking a beluga whale in the open ocean.

I moved the above posts from "Size Comparisons (The Grand Arena)" to here. They all arrived ( somehow ) out of correct order.

Alaskan peninsula brown bear vs salmon shark in shallow water, a very weird match up. I tend to agree with Taker on this one. Shallow water wont be the best place for the shark, the bear's head would be over the water line at 4 feet, an 1000 pounder would be double than the largest salmon shark at 500 lbs. If the shark gets the bite first its over. But also, the bear can get a hold if it and either claw it down or even rapid bite it. Depends who gets who first. My opinion on this is 50%, can go either way.

How many of you are avid watchers during Shark week?
I know I am. There have been many instances (accounts) of humans surviving shark attacks in shallow water, even from Bull Sharks which are considered highly aggressive. They usually come away with an ugly injury, but death is quite rare. Most experts attribute this to the Shark just taking a bite to see what you taste like and if he likes it he may go for more. I feel the same would be true for a Bear. A shark may make an initial bite, a taste if you will, but in this case the food source is much larger and can fight back with a vengeance. Remember Bears are excellent fisherman and to them a shark would be just a big fish. Now I'm not taking about a 10ft. plus Tiger shark or Great White mind you but a 6 or 7 ft. Shark in shallow water is in the realm of capabilities of a large Brown bear to inflict major damage or even death to a shark that size. It's true the Shark moves swiftly, but once the shark has made his taste bite the Bear is fully aware of what is transpiring and will be on the defensive and those 4 inch claws and teeth that he uses to effortlessly snag Salmon will be lethal weapons to a smaller shark. IMO it would take multiple Sharks in a feeding type frenzy in shallow water to do in a 1000 lb Bear.
That being said, move this to deeper water and everything changes and the Bear will not be able to defend himself nearly as well. 80/20 in favor of Bear in shallow water, 70/30 in favor of multiple sharks in deeper water.

Sharks actually do not like the taste of human flesh. They do mistake us for their favourite prey which among them are seal turtles and seals. A single bite is enough to slice of huge chunks of flesh and cause blood lost.

www.cheatsheet.com/culture/why-sharks-attack-shallow-water.html/ Shallow water seems like a strange place for a shark attack — after all, they sometimes get so close to shore that they can barely move! Nonetheless, it happens. While it’s hard to say for sure why sharks attack in shallow water, some species — such as the bull shark — like to feed in murky, warm, shallow waters. That preference often results in swimmer or surfer encounters. However, tasty human flesh isn’t what causes them to attack. According to National Geographic, bull sharks are the biggest threat to humans surfing or swimming in shallow water (great whites and tiger sharks are a close second and third). Because they prefer the same swimming conditions as humans (tropical shorelines) and are extremely territorial, they are considered the most dangerous sharks in the world. On top of that, they’ll eat practically anything — including their own kind.

Polar bears and Greenland sharks might encounter each other once in a while. I have often wondered about this myself: www.bbc.com/news/science-environment-37047168 400-year-old Greenland shark ‘longest-living vertebrate’ - By Rebecca Morelle - Science Correspondent, BBC News Greenland sharks are now the longest-living vertebrates known on Earth, scientists say. Researchers used radiocarbon dating to determine the ages of 28 of the animals, and estimated that one female was about 400 years old. The team found that the sharks grow at just 1cm a year, and reach sexual maturity at about the age of 150. The research is published in the journal Science. Lead author Julius Nielsen, a marine biologist from the University of Copenhagen, said: "We had our expectations that we were dealing with an unusual animal, but I think everyone doing this research was very surprised to learn the sharks were as old as they were." The former vertebrate record-holder was a bowhead whale estimated to be 211 years old. But if invertebrates are brought into the longevity competition, a 507-year-old clam called Ming holds the title of most aged animal. Slow swimmers Greenland sharks are huge beasts, that can grow up to 5m in length. They can be found, swimming slowly, throughout the cold, deep waters of the North Atlantic. With this leisurely pace of life and sluggish growth rate, the sharks were thought to live for a long time. But until now, determining any ages was difficult. For some fish, scientists are able to examine ear bones called otoliths, which when sectioned, show a pattern of concentric rings that scientists can count as they would the rings in a tree. Sharks are harder, but some species, such as the Great White, have calcified tissue that grows in layers on their back bones, that can also be used to age the animals. "But the Greenland shark is a very, very soft shark - it has no hard body parts where growth layers are deposited. So it was believed that the age could not be investigated," Mr Nielsen told the BBC. However the team found a clever way of working out the age. "The Greenland shark's eye lens is composed of a specialised material - and it contains proteins that are metabolically inert," explained Mr Neilson. "Which means after the proteins have been synthesised in the body, they are not renewed any more. So we can isolate the tissue that formed when the shark was a pup, and do radiocarbon dating." The team looked at 28 sharks, most of which had died after being caught in fishing nets as by-catch. Using this technique, they established that the largest shark - a 5m-long female - was extremely ancient. Because radiocarbon dating does not produce exact dates, they believe that she could have been as "young" as 272 or as old as 512. But she was most likely somewhere in the middle, so about 400 years old. It means she was born between the years of 1501 and 1744, but her most likely date of birth was in the 17th century. "Even with the lowest part of this uncertainty, 272 years, even if that is the maximum age, it should still be considered the longest-living vertebrate," said Mr Nielsen. Conversely, if her age is at the upper end of the scale, she will have out-lived Ming the clam - although her age has a greater probability of lying in the middle. The team believes the animals only reach sexual maturity when they are 4m-long. And with this new, very lengthy age-range, it suggests this does not occur until the animals are about 150 years old. The researchers say this has consequences for future conservation of the animals.

Post #17 Spotlight: Slow swimmers - Greenland sharks are huge beasts, that can grow up to 5m in length ( 16.40 feet ). They reach sexual maturity at roughly 150 years old. geerg.ca/greenland-shark/ The Greenland shark is the largest member of the Somniosidae family. It is the second largest* carnivorous shark after the great white and it is the largest Arctic fish. *Equal length as the white shark but approximately half the girth. Maximum length: Up to 7.3m (24′) Average length: 2.5m to 4.5m (8′ to 15′) Weight: Up to 1,200kg (2,645 lbs) (Koefoed 1957) The skin of the Greenland shark is covered in dermal denticles, which are more like teeth that fish scales. The denticles reduce drag and turbulence, and this enables the shark to swim more stealthily. The denticles are very sharp. Divers must therefore avoid intentional or accidental contact with a Greenland shark as the denticles may damage or even pierce a drysuit. The Greenland shark is an opportunistic predator that will eat just about anything that comes across its path, either dead or alive. However, we believe that it is primarily a scavenger. VERIFIED STOMACH CONTENTS Fish: Arctic char, Atlantic halibut, Atlantic salmon, capelin, cod, eelpout, eels, Greenland halibut (turbot), grenadier, haddock, herring, lumpfish, lycodes, pollack, sculpins, sebastes, skates and other sharks, spotted wolffish. Mammals: beluga, narwhal, porpoise, seals, and other animals including a dog, horse, reindeer, moose, and white (polar) bear remains. Invertebrates: crustaceans, gastropods, jellyfish, octopus, sea stars (sun stars & brittle stars), squid, urchins, whelk and other snails. Others: Bird remains, kelp.
