How do harp seals survive? The blubber helps to keep them warm since they live in a very cold environment.   When harp seals are born, they have a white … fur coat. The fur coat camouflages into the snow to protect them from their enemies on land.

Seal Feeding What do Seals Eat? Seals find the foods that they need in the water around them, which is why you will only find them where there is plenty of water. Their primary sources of food include fish but they will consume just about any type of meat they can get in the water. Other types of food that they enjoy include squid, octopus, and shellfish. Sometimes food sources are low due to the big ships fishing for such items in the same waters as the seals hunt.

- These two species overlap in their summer range but are recognized as separate species based on their ecological, behavioral, and morphological differences. For example, spotted seal preferred habitat is the edge of the pack ice in areas of loose floes while harbor seals avoid sea ice. Spotted seal pups are born in white lanugo on sea ice while harbor seal pups shed their lanugo before they are born and their pups are born on land.

How Diving Mammals Stay Underwater for So Long Diving mammals will slow their heart rate, stop their breathing, and shunt blood flow from their extremities to the brain, heart, and muscles when starting a dive. But champion divers, such as elephant seals, can hold their breath for about two hours. It was known that they rely on internal oxygen stores when they're down there, said Michael Berenbrink, a zoologist at the University of Liverpool, England, who specializes in how animals function.

- Looks like it's because of diet. 1  Polar bears eat seals. 2  Seals eat fish. 3  Fish have a lot of vitamin A in them.  Since seals eat a lot of fish, they collect a lot of vitamin 1  A. Bear collect even more because of what they 2  eat. One of the functions of the liver is to get rid of stuff.

- Adult. spotted seals weigh about 200 pounds (90 kg) and measure about 5 feet (1.5m) long. Food Habits: Adult spotted seals eat a variety of fish, crustaceans, and cephalopods and their diet varies with age, season, and location. Near Shishmaref the top five prey species are cod, herring, smelt, shrimp, and amphipods.

Why whales can hold their breath for a long time â and you can't Why whales can hold their breath for a long time — and you can't. Marine mammals have all kinds of wonderful adaptations to lead a comfortable life underwater, such as flippers and insulating blubber. Whales even have eyes that can see in monochrome, which is especially valuable deep beneath the surface where sunlight is at a premium.

Polar Bear Arctic Adaptations. Polar bears live in one of the planet's coldest environments and depend on a thick coat of insulated fur, which covers a warming layer of fat. Fur even grows on the bottom of their paws, which protects against cold surfaces and provides a good grip on ice. The bear's stark white coat provides camouflage in surrounding snow and ice. But under their fur, polar bears have black skin—the better to soak in the sun's warming rays. Hunting.

- The answer varies by species. Harbor seals can sleep underwater for as long as 20 minutes. To stay under this long, they slow their heartbeat way down. They usually only dive for three or four minutes at a time. Some seals in the Arctic (Weddell seals) spend a lot of time under the ice and can hold their breath for an hour, and maybe much longer than that. How deep do they dive? Harbor seals can dive up to 90 meters (300 feet), but they usually only go three meters (ten feet) below the surface.

Harbor Seal 1 Adult harbor seals eat 5% to 6% of their body weight per day, about 4.5 to 8.2 kg (10-18 lb.).  Harbor seals don't chew their food. They swallow their food whole or tear it into chunks. With their back molars, they crush shells and crustaceans.

How Do Seals Protect Themselves From Predators? Seals have very thick fur and an even thicker layer of blubber to keep them warm in their cold climate. Because of their thick skin, it is hard for most animals to attack seals simply because their predators must have large teeth. For this reason, the two main predators of all seal species are sharks and killer whales. A seal's first line of defense from sharks and whales is their ability to detect and move away from danger.

Polar Bears Polar bears need an average of 2 kg (4.4 lb.) of fat per day to obtain enough energy to survive. A ringed seal weighing 55 kg (121 lb.) could provide up to eight days of energy for a polar bear. Hibernating polar bears do not eat.

Polar bear The polar bear is an excellent swimmer and often will swim for days. One bear swam continuously for 9 days in the frigid Bering Sea for 687 km (400 mi) to reach ice far from land. She then travelled another 1,800 km (1,100 mi). During the swim, the bear lost 22% of her body mass and her yearling cub died.

The 4 Most Endangered Seal Species Most other seal species and subspecies appear to be fairly healthy. But that doesn't mean that every seal is safe. Increasingly, small populations of seals find themselves isolated and at risk, if not on the verge of being wiped out.

What to do when you see a seal This natural process of shedding its coat suggests the seal is healthy, as it requires a lot of energy. In fact, it stirs so many hormones and takes so much energy that it may be the reason the seal is on the beach. Most likely, the seal needs a nap. Nash points to the seal’s belly.

Polar Bear This fat may also help the bears float in the water. It is 2 to 4 inches (5 to 10 centimeters) thick. Unlike brown bears and black bears, polar bears do not hibernate, and only pregnant females over-winter in dens. While in the den, the pregnant female’s activity level decreases and her metabolism slows down. During this period, she gives birth and nurses her cubs.

How do harp seals survive? (these are mostly humans and polar bears) Harp Seals can swim and have been known to hold their breath for up to 10 minutes. They mostly eat penguins, fish, the majority of crustaceans. NOTE! Harp seals live in the Arctic Region while Penguins live in the Antarctic region.

Polar Bear The ringed seal is the polar bear’s main prey, as it is the most numerous seal in the Arctic. Polar bears typically kill and eat every four to five days. These bears eat just about anything, if they have the opportunity, but it is important to remember that they need access to the high-calorie diet that seals provide.

1730days sinceProject Due Date Living in the Arctic, the polar bear faces many challenges. One of the many challenges is a shrinking habitat. We humans have greatly contributed to the shrinking of the sea ice, which makes finding food harder for the polar bears. In a way, polar bears face loss of habitat space and food. There are not many animals that will feast on the polar bears, so they have no need to fear predators. As we humans slowly encroach on the polar bear habitat, we also pollut parts of their environment. Information and Media Sources: Survival Adaptations: Polar bears are normally very solitary, and that can help them avoid fighting each other. In certain scenarios, the polar bear would rather escape than fight. As young cubs, polar bears play-fight. Play-fighting while they're young helps them prepare for competition during mating season.

Polar Bears Their habitat includes both land and sea ice. Often polar bears live on ice and drift from one area to another. Massive areas break off and shift locations, sometimes putting mother and cubs in danger. In fact baby polar bears can become stranded when blocks drift far apart since cubs cannot swim long distances.

Elephant Seals During the spring and summer months, elephant seals return to Año Nuevo for their annual molts. At sea, elephant seals typically dive 20 minutes to a depth of 1,000 to 2,000 feet in search of food: rays, skates, rat fish, squid, and small sharks. The maximum recorded depth is 5,015 feet by a male in 1991. The females eat nothing while they are giving birth, nursing, and mating, and the males go without food for up to three months at that time.

How are brown bears adapted to defend themselves? If you make it past the claws and teeth you will also find that the fur and skin of a Brown Bear are very thick, up to as much as 8cm thick. A would be predator has to get through all this to even begin to hurt the bear. Bears are also phenomenally strong and their muscle provides yet another layer of protection against attack. They can pick up 220kg seals from the water using their jaws and then carry them ashore to eat. Their jaws, by the way, are powerful enough to bite through 15cm thick trees. Lastly they are athletic beasts.
