How Do Elephant Seals Catch Their Food?

How Do Elephant Seals Catch Their Food? Southern elephant seals feed exclusively at sea. The main sources of food are fish and squid. Prey is captured both near the surface and very deep underwater. Southern elephant seals locate prey with their vision; their large eyes are an adaptation allowing them to take advantage of the bioluminescence of some prey.

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.

What do elephant seals use their nose for? Elephant seals aren’t named for their size. Rather, the males develop noses that kind of look like elephants’ trunks. They inflate their noses in order to scare other males away — to mate, they have to fight for dominance.

How do elephant seals navigate? Back at the surface, instead of swimming in straight lines the seals switched direction by anything up to 360 deg. Matsumura and her colleagues suspect that the seals use visual landmarks to guide their choice of bearing above the surface.

How deep do elephant seals dive for food?

Elephant seals are remarkable divers, spending up to 1.5 hours underwater and reaching depths of more than 1700 meters in their search for food.

How does an elephant seal protect itself?

Both male and female walruses have tusks, which are overgrown canine teeth that can be as long as 3 feet. They use their tusks in self-defense — against predators and, in the case of males, rival walruses — and also employ them as ice-picks to lift themselves out of the water.

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.

Do elephant seals eat sharks?

What does a seal eat?

Varied diets

All seals eat other animals, and most rely on fish caught out at sea. But a few species break the mold. For instance, leopard seals make a living hunting down penguins and even other seals.

How long can elephant seals hold their breath?

Male elephant seals can hold their breath for longer than almost any other mammal, diving beneath the waves for up to two hours without surfacing for air. Elephant seals live for just two months of the year on land.

How long can Weddell seals hold their breath?

Weddell seals can dive up to 2,000 feet down and stay under for up to 45 minutes. But no matter how deep they dive, like all marine mammals, they must surface to breathe. If natural openings are not available, Weddell seals use their teeth to open and maintain air holes in the ice pack.

Do elephant seals eat penguins?

Penguins are frequently killed and eaten by predators like fur seals, leopard seals, elephant seals, and other ground and marine predators.

Do elephant seals eat babies?

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 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 much blood does an elephant seal have?

The blood volume of the adult female elephant seal obtained by Welcker’s method can be expressed as 207 ml/kg empty live weight, compared with a figure of 80 ml/kg in an adult human being.

Why can the elephant seal hold its breath for so long?

Special properties of an oxygen-binding protein in the muscles of marine mammals, such as seals, whales and dolphins, are the reason these animals can hold their breath underwater for long periods of time, according to a new study. In fact, the amount was so high in the muscle that it almost looked black in color.

Can humans outrun elephant seals?

How do elephant seals survive?

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.

Why are elephant seals endangered?

After whales became scarce, elephant seals were hunted to the brink of extinction primarily for their blubber, which people used for lamp oil. Today, the northern elephant seal population has rebounded to approximately the size it was before hunting.

How does a seal avoid sharks?

“Stealth and ambush are key elements in the white shark’s predatory strategy,” said Hammerschlag. According to the authors, if a seal is not disabled during the shark’s initial shark, the small seal can use its highly maneuverable body to leap away from the shark’s jaws to evade a second strike.

How do seals feed?

Common seals mostly forage in shallow coastal waters, usually on the seabed, but occasionally in mid-water. They dive for just a few minutes, swallowing their prey whole underwater or bringing larger catches up to the surface, where they shake them into more manageable pieces.
