They can hold their breath for more than 100 minutes – longer than any other noncetacean mammal. With time, Coolio – at the Pittsburg zoo – should help us increase our understanding of elephant seal care. Elephant seals dive to 1,550 m (5,090 ft) beneath the ocean's surface (the deepest recorded dive of an elephant seal is 2,388 m (7,835 ft) by a southern elephant seal, while the record for the northern elephant seal is 1,735 m (5,692 ft)). Elephant seals are large, oceangoing earless seals in the genus Mirounga. [1] The oldest known unambiguous elephant seal fossils are fragmentary fossils of an unnamed member of the tribe Miroungini described from the late Pliocene Petane Formation of New Zealand. [9] Males and females lose up to a third of their body weight during the breeding season. The elephant seal is a distinctive marine mammal known as a “pinniped.” Pinniped include are seals, sea lions, and walruses. [11] The bull's proboscis is used in producing extraordinarily loud roaring noises, especially during the mating season. [9] Male elephant seals use fighting, vocal noises, and different positions to determine who will be deemed the dominant male. [9] The new pups will spend up to 10 additional weeks on land learning how to swim and dive.[9].

They have large sinuses in their abdomens to hold blood and can also store oxygen in their muscles with increased myoglobin concentrations in muscle. Elephant seals congregate in large numbers on beaches to breed. The northern elephant seal is a conservation success story. [9], Elephant seals have a helpful feature in their bodies known as the countercurrent heat exchanger to help conserve energy and prevent heat loss.

As of 2018, there is only one known elephant seal held in human care. This story has been shared 312,597 times. The IUCN lists both species of elephant seal as being of least concern, although they are still threatened by entanglement in marine debris, fishery interactions, and boat collisions. [9] When it comes time to molt, they will haul out on land to shed their outer layer, and will not consume any food during this time. Sub-adult male elephant seals spar on Drakes Beach. After whales became scarce, elephant seals were hunted to the brink of extinction, primarily for their blubber, which was used for lamp oil.

[12] This is important during the mating season when the seals do not leave the beach to feed, and must conserve body moisture as there is no incoming source of water. Elephant seals are solitary for most of their lives, congregating only during the breeding seasons.

[9], Milk produced by elephant seals is remarkably high in milkfat compared to other mammals.

The most northerly breeding location on the Pacific Coast is at Race Rocks, at the southern tip of Vancouver Island in the Strait of Juan de Fuca. Female elephant seals give birth to a single pup after an 11-month gestation.

Elephant seals are shielded from extreme cold more by their blubber than by fur.

[8] Elephant seals are considered true seals, and fall under the family Phocidae. Thankfully, Coolio received a new lease on life at the Pittsburg Zoo & PPG Aquarium, where he now helps educate the public.

They can hold their breath for more than 100 minutes[15][16] – longer than any other noncetacean mammal. The seals return to their breeding grounds, known as “rookeries,” in winter.

[23] Males reach maturity at five to six years, but generally do not achieve alpha status until the age of eight, with the prime breeding years being between ages 9 and 12.

On average, the southern elephant seal tends to be larger than the northern species.

[8], Due to evolutionary changes, their ear has been modified to work extremely well underwater. [7], Elephant seals are marine mammals classified under the order Pinnipedia, which, in Latin, means feather- or fin-footed. [25] Breeding success is much lower for first-time mothers relative to experienced breeders. Elephant seals are now protected from harm under the Marine Mammal Protection Act , and their numbers have bounced back to a healthy population level. [9] This unique nasal structure recycles moisture when they breathe and helps prevent water loss.

[9], Elephant seals take their name from the large proboscis of the adult male (bull), reminiscent of an elephant's trunk, and considered a secondary sexual characteristic.

[20], Elephant seals are able to slow down their heartbeat (bradycardia) and divert blood flow from the external areas of the body to important core organs.

Naval officers try to coax it back to the sea using large tarpaulins in a second viral video from The Guardian, which concludes with the rescuers ushering the two-ton sea beast into the water amid the claps and cheers of overjoyed bystanders. In southern Chile, there is a small colony of 120 animals at Jackson Bay, Admiralty Sound (Seno Almirantazgo), Tierra del Fuego. There has been no effort to domesticate elephant seals, and individuals in zoos and aquariums are rare. The northern elephant seal, somewhat smaller than its southern relative, ranges over the Pacific coast of the U.S., Canada and Mexico. Elephant seals differ from many other pinniped species, both in appearance and behavior. We've received your submission.

[9] Females cluster in groups called harems, which could consist of up to 50 females surrounding one alpha male. The footage shows the bewildered pinniped — the largest of its kind at up to four tons — lumbering awkwardly down the road. [9] The last two to three days, however, females will be ready to mate, and the dominant males will pounce on the opportunity. When on land, elephant seals move about using an undulating or worm-like motion.

The marine mammal became stranded in the seaside city after getting disoriented while coming ashore. [9], Birth on average only takes a few minutes, and the mother and pup have a connection due to each other's unique smell and sound. Sitemap The largest populations of Southern elephant seals are found on South Georgia, Macquarie Island, Falkland Island, Heard Island, and Kerguelen Island. [9] The vibrissae are connected to blood vessels, nerves, and muscles making them an important sensing tool. Privacy Notice 274,386, This story has been shared 149,766 times.

For the superfamily of sea slugs, see, CS1 maint: multiple names: authors list (, "WCS Chile > Especies > Elefantes marinos", "Rapid Response of a Marine Mammal Species to Holocene Climate and Habitat Change", "Synopsis of the species of the class Mammalia", "Conservation Advice: Mirounga leonina, southern elephant seal", "Elephant Seal, Elephant Seal Profile, Facts, Information, Photos, Pictures, Sounds, Habitats, Reports, News – National Geographic". [9] The females and juveniles will molt first, followed by the sub adult males, and finally the large mature males.

The southern elephant seal is found in the Southern Hemisphere on islands such as South Georgia and Macquarie Island, and on the coasts of New Zealand, South Africa, and Argentina in the Peninsula Valdés. A single adult male will protect a harem of 40 or 50 females, and he will breed with them all.

Elephant seals spend most of their lives at sea, roaming the open ocean and the depths of the seas in search of food. The Northern elephant seal species lives offshore in the open ocean most of the year.

[9] Phocids (true seals) are characterized by having no external ear and reduced limbs.

[9], Elephant seals have external whiskers called vibrissae to help them locate prey and navigate their environment. The skin has to be regrown by blood vessels reaching through the blubber. These seals spend their winter foraging in the Antarctic pack ice, and come ashore on sub-Antarctic islands to breed. This story has been shared 149,766 times.

[9] The turbinate process, another unique adaptation, is very beneficial when these seals are fasting, breeding, molting, or hauling out. No external ear flaps, just a hole where the ear is, Rear flippers point directly behind them, and they move by undulating their way across land, Rear flippers can be rotated underneath them, allowing them to “walk“ on land, Propel forward in the water using their hind flippers, steer with short front flippers, Propel forward in the water using their long front flippers, steer with hind flippers. In addition, they have a larger proportion of oxygen-carrying red blood cells. When molting occurs, the seal is susceptible to the cold, and must rest on land, in a safe place called a "haul out".

While he nearly made a full recovery, Coolio’s eyes were permanently damaged, and he was deemed non-releasable. 149,766, © 2020 NYP Holdings, Inc. All Rights Reserved The average lifespan of a Northern Elephant Seal is 9 years, while the average lifespan of a Southern Elephant Seal is 21 years. [9] The reduction of their limbs helps them be more streamlined and move easily in the water.

[9] Sexual dimorphism is extreme, with male elephant seals weighing up to 10 times more than females,[10] and having a prominent proboscis. This story has been shared 274,386 times. [8] In addition to these adaptations, tissues in the ear canal allow the pressure in the ear to be adjusted while these seals perform their deep dives.

[10], Elephant seals spend up to 80% of their lives in the ocean.
