How Do Elephant Seals Dive So Deep? Elephant seals have a very large volume of blood, allowing them to hold a large amount of oxygen for use when diving. In addition, they have a larger proportion of oxygen-carrying red blood cells. These adaptations allow elephant seals to dive to such depths and remain underwater for up to two hours.
How deep do elephant seals dive? 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 can elephant seals dive longer than humans? A group of involuntary responses called the mammalian diving reflex that reduce oxygen consumption during a breath-hold dive are more extreme in elephant seals than humans.
How long can an elephant seal dive for? Southern elephant seals can dive from 400 to 1,000 meters (1,300 to 3,300 feet) for up to 20 minutes at time. The deepest recorded dive doubled that average, reaching a little over 2,100 meters (6,890 feet) deep. To stay underwater so long, southern elephant seals exhale before diving to get gases out of their bodies.

Dives last 3 to 7 minutes and are usually in shallow waters. But they can dive deeper. Adult harbor seals can dive as deep as 1500 feet and stay underwater over 30 minutes! To do this, they rely on their amazing oxygen storage capabilities.
Do seals sleep underwater?
Seals sleep in the water as well as on land. Because they are sleeping and not actively swimming, they can stay under water much longer than when hunting for food. There are known incidents where seals stay under water up to half an hour, however on the average, their stay is not longer than fifteen minutes.
How long can northern elephant seals hold their breath?
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.

How deep can seals swim?
Seals dive for three minutes at a time typically, but they can stay under water as long as 30 minutes and dive as deep as 1,600 feet.
Do elephant seals have any predators?
Large southern elephant seals have few predators, but killer whales, leopard seals, and some large sharks are known to feed on this species. Historically, southern elephant seals were hunted to very low numbers because of the value and volume of their blubber, which was rendered into oil.
Which animal can dive the deepest?
Cuvier’s beaked whales (Ziphius cavirostris) are master divers. These creatures hold the record for deepest plunge by a marine mammal. One whale dived to depths of nearly 3,000 meters (almost 1.9 miles). This species also holds the record for the longest dives.
How big can elephant seals get?
Adult males are enormous – at least six times larger than polar bears and nearly twice the size of the next largest seal (the northern elephant seal). Males reach lengths of nearly 20 feet (6 m) and weights of more than 8000 pounds (3700 kg).
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.
What does a seal eat?
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.
What is bigger an elephant seal or a walrus?
Among the most amazing of pinnipeds are the elephant seals. They are the biggest of pinnipeds – bigger even than walruses – there being a record of a giant male Southern elephant seal that was between 6.5 and 6.8 m long and weighed over 4000 kg (Carwardine 1995).
Do elephant seals mate for life?
Sneaker males hang out along the periphery of the rookery and try to mate when the harem master is asleep or busy. It is believed that only about one percent of all male elephant seals actually get to mate during their life. Males have a very hard life and live a considerably shorter time than the females.
Why do elephant seals throw sand on themselves?

Do whales sleep underwater?
If asked, do whales sleep underwater? The answer is simple, YES they do. Their bodies shut down but only half of their mind stays at rest so that they conscientiously remember to breathe. Breathing near the surface where whales sleep allows them to breathe more conscientiously, meaning each and every breath counts.
Can seals drown?
Most seals come up for air every two or three minutes. Some of the larger seals can stay under water much longer than this. In the polar regions some seals may go fishing under the ice. No doubt some of these daring fellows get trapped and drown.
How do marine mammals dive so deep?
In deep-diving whales and seals, the peripheral airways are reinforced, and it is postulated that this allows the lungs to collapse during travel to depth. Instead deep-diving whales and seals rely on large oxygen stores in their blood and muscle. Several adaptations enable this.
Are elephant seals bigger than elephants?
Southern elephants are the largest of all seals. Males can be over 20 feet long and weigh up to 8,800 pounds. But these massive pinnipeds aren’t called elephant seals because of their size.
