What adaptations do elephant seals have?

Elephant seals’ blubber accounts for much of their weight and is an adaptation to help them stay warm. The bigger an animal is, the less surface area (or skin exposed to the air) it has in relation to its volume, so it loses less heat.

What is an elephant seals habitat?

Habitat. Northern elephant seals reside terrestrially on the sandy, rocky or muddy shores of the coastline, particularly on offshore islands. They typically aggregate in large groups while on land. These animals spend only 10% of their time on land, during reproduction and moulting.

How many flippers does an elephant seal have?

They have visible ear flaps, strong front flippers, and the ability to walk on all four flippers when on land. Males are larger than females—in some species they can be up to four times larger. While other pinnipeds rely on their blubber to keep warm, fur seals rely on a thick coat of fur.

What is the difference between seal and elephant seal?

True seals, such as elephant seals, differ from other pinnipeds in two easy-to-recognize ways. When it comes to scratching, it’s the opposite, true seals use their fore flippers while sea lions use their rear flippers. And in general, true seals have more blubber and are more streamlined.

What are two reasons why elephant seals come on land?

While elephant seals spend most of their time swimming, they also gather on beaches in groups called colonies. One reason they come to land is to give birth and breed. Males arrive before females. They battle for dominance, deciding who will have large harems of females.

Is blubber and fat the same thing?

Blubber is different than most types of fat. Blubber is much thicker and contains many more blood vessels than the fat found in land animals, including humans. Blubber is so unique that many marine biologists don’t refer to blubber as fat at all.

What is seal fat used for?

Raw seal fat is often used to treat skin ailments. Applied in thin slices or rubbed in, it is effective on cuts, burns, wounds and impetigo, and helps stop bleeding. Raw seal fat can also be chewed (for a sore throat) and used in drops (in the eyes for snow blindness and in the ear for earache).

How does blubber keep animals warm?

In addition to providing insulation, blubber actually manipulates a mammal’s blood vessels to help it stay warm. Blubber is more densely packed with blood vessels than a typical layer of fat, and when the temperature drops, the blubber constricts those blood vessels to reduce the blood flow in the animal.

How fast can elephant seals move on land?

Southern elephant seals can move along the ground at about 5 kph (3 mph) while on land. While swimming, southern elephant seals move at speeds around 5 – 10 kph (3 – 6 mph).

Why do seals jump out of the water?

The behavior that led to the collision is known as seal “porpoising,” in which they jump in and out of the water while moving at high speeds. Curious and playful by nature, the seals were likely trying to get a better look at the kayakers moving through their natural surroundings.

Why do elephant seals have such a big nose?

How does an elephant seal obtain its food?

Answer: The main sources of food are fish and squid. Prey is captured both near the surface and very deep underwater. The seals have been known to eat bottom dwelling fish from the ocean’s darkest depths.

How has the elephant seal adapted to Antarctica?

Special adaptations

They can dive to over 1,500m and can stay submerged for up to 2 hours. Their red blood cells may, as an adaptation for diving, contain more haemoglobin than normal. These extra red blood cells make elephant seals’ blood very thick. Their muscles are also used to store oxygen.

What do elephant seals prey on?

Large southern elephant seals have few predators, but killer whales, leopard seals, and some large sharks are known to feed on this species.

Where do elephant seals migrate to?

Northern elephant seals migrate twice a year between the Californian and Mexican beaches and their feeding areas in the north Pacific Ocean. The adult males feed in the Gulf of Alaska and near the eastern Aleutian Islands, while the adult females feed further south between 40-45°N.

How do elephant seals molt?

The catastrophic molt means that each elephant seal will stay ashore for about twenty-five to twenty-eight days in order to shed all of its fur. The fur sheds in patches with the epidermal skin attached revealing a new dark gray fur underneath ready for immediate use.

How do elephant seals behave?

They collect a harem of 40 to 50 females, which are much smaller than their enormous mates. Males battle each other for mating dominance. Some encounters end with roaring and aggressive posturing, but many others turn into violent and bloody battles.

How long can elephant seals hold their breath?
