The skins of fur seals and phocids are made into coats, and the tusks of walruses continue to be used for carvings or as ornaments. In the 1980s and 1990s, South African politicians and fisherman demanded that the fur seals be culled, believing that the animals competed with commercial fisheries. Overall, they tend to be larger than other carnivorans; the southern elephant seal is the largest carnivoran. Large sharks are another major predator of pinnipeds—usually the great white shark but also the tiger shark and mako shark. The individual hairs on the coat, known collectively as lanugo, can trap heat from sunlight and keep the pup warm. [38] Pinnipeds are typically countershaded, and are darker colored dorsally and lighter colored ventrally, which serves to eliminate shadows caused by light shining over the ocean water. Females are generally slightly larger than the males on average. Visual displays also occur: Weddell seals will make an S-shaped posture when patrolling under the ice, and Ross seals will display the stripes on their chests and teeth when approached. The Leopard seal attempts to escape in the water, but the Elephant seal grab it by the tail and drags it away. Sharks usually attack by ambushing them from below. [55], The pinniped ear is adapted for hearing underwater, where it can hear sound frequencies at up to 70,000 Hz. [67] Research is ongoing to determine the function, if any, of these shapes on detection ability. [15] This is supported by a 2006 molecular study that also found that the Australian sea lion and New Zealand sea lion are more closely related to Arctocephalus than to other sea lions. The ancestor of the Baikal seal migrated into Lake Baikal from the Arctic (via the Siberian ice sheet) and became isolated there. [43] Pinnipeds tend to be slower swimmers than cetaceans, typically cruising at 5–15 kn (9–28 km/h; 6–17 mph) compared to around 20 kn (37 km/h; 23 mph) for several species of dolphin.

In lobodontine seals, females are slightly longer than males. Seals usually require cool, nutrient-rich waters with temperatures lower than 20 °C (68 °F). [56] One study of three species—the harbor seal, California sea lion and northern elephant seal—found that the sea lion was best adapted for airborne hearing, the harbor seal was equally capable of hearing in air and water, and the elephant seal was better adapted for underwater hearing. The sea lion's hind flippers are stronger and more flexible. In lobodontine seals, females are slightly larger than males. The discovery of Puijila in a lake deposit suggests that pinniped evolution went through a freshwater transitional phase. Pinnipeds may move further inland and rest in sand dunes or vegetation, and may even climb cliffs. Leopard Seal - Hydrurga leptonyx The leopard seal (Hydrurga leptonyx), also referred to as the sea leopard, is the second largest species of seal in the Antarctic (after the southern elephant seal). Sea lions are distinguished by their rounder snouts and shorter, rougher pelage, while fur seals have more pointed snouts, longer fore-flippers and thicker fur coats that include an undercoat and guard hairs. [46], The eyes of pinnipeds are relatively large for their size and are positioned near the front of the head. The cornea has a flattened center where refraction is nearly equal in both water and air. Then the Leopard seal bites the Elephant seal on the side, but the Elephant seal's blubber protected it. In addition, walruses feed solitarily but are often near other walruses in small or large groups that may surface and dive in unison. [110], Lek systems are known to exist among some populations of walruses. The seals were easy targets for organized sealers, fishermen, turtle hunters and buccaneers because they evolved with little pressure from terrestrial predators and were thus "genetically tame". [17] Walruses have pterygoid bones that are broad and thick, frontal bones that are V-shaped at the anterior end and calcaneuses with pronounced tuberosity in the middle. Small intestine lengths range from 8 times (California sea lion) to 25 times (elephant seal) the body length. Older crabeater seals commonly bear scars from failed leopard seal attacks; a 1977 study found that 75% of a sample of 85 individual crabeaters had these scars. They feed largely on fish and marine invertebrates; a few, such as the leopard seal, feed on large vertebrates, such as penguins and other seals. Killer Whale season is coming- this is one of the highlights from last May. With the Japanese sea lion and the Caribbean monk seal recently extinct, ten more are considered at risk, as they are ranked "Endangered" (Hawaiian monk seal, Mediterranean monk seal, Galápagos fur seal, Australian sea lion, New Zealand sea lion, Caspian seal, and Galápagos sea lion) or "Vulnerable" (northern fur seal, hooded seal, and walrus). This and its lack of orbital roof allow it to protrude its eyes and see in both frontal and dorsal directions. The leopard seal's only advantage is agility. However, Weddell seal hunting is prohibited between September and February if the animal is over one year of age, to ensure breeding stocks are healthy. Elephant seals are large, oceangoing earless seals in the genus Mirounga. In between nursing bouts, the females leave their young onshore to forage at sea. Terrestrial locomotion is easier for phocids on ice, as they can sled along. Pinnipeds that breed on fast ice tend to cluster together more than those that breed on drift ice. [66] The vibrissae of phocids are undulated and wavy while otariid and walrus vibrissae are smooth. [38], Pinnipeds have a simple stomach that is similar in structure to terrestrial carnivores. The last recorded individual was a juvenile in 1974. The overall length of this seal is 2.4-3.5 m (7.9-11.7 ft) and weight is from 200 to 600 kilograms (440 to 1,300 lb). Pinnipeds do not have an appendix. Animal Face Off: Ultimate Dinosaur Rumble Part 2, https://animalfaceoff.fandom.com/wiki/Elephant_Seal_vs._Leopard_Seal?oldid=8329. [133] Young pinnipeds typically learn to swim on their own and some species can even swim at birth. [155] In Inuit mythology, the goddess Sedna rules over the sea and marine animals. New Zealand sea lions feed on pups of some fur seal species, and the South American sea lion may prey on South American fur seals. [172] The Japanese sea lion was common around the Japanese islands, but overexploitation and competition from fisheries drastically decreased the population in the 1930s. The leopard seal is large and muscular, with a dark grey back and light grey on its stomach. [99] Some species may swallow stones or pebbles for reasons not understood. Two Pinnipeds are ready for an Antarctic Showdown, as the Elephant seal and Leopard seal go head to head. [43] Some species leap out of the water, which may allow then to travel faster. [12] The anterior end of an otariid's frontal bones extends between the nasal bones, and the supraorbital foramen is large and flat horizontally. The Greeks associated them with both the sea and sun and were considered to be under the protection of the gods Poseidon and Apollo. Next Episode: Carnotaurus vs. Cryolophosaurus. [16], In a 2012 review of pinniped taxonomy, Berta and Morgan Churchill suggested that, based on morphological and genetic criteria, there are 33 extant species and 29 subspecies of pinnipeds, although five of the latter lack sufficient support to be conclusively considered subspecies. [9] Of the three extant families, the Otariidae and Odobenidae are grouped in the superfamily Otarioidea,[10] while the Phocidae belong to the superfamily Phocoidea. Delayed implantation postpones the birth of young until the female hauls-out on land or until conditions for birthing are favorable. Elephant seals are large, oceangoing earless seals in the genus Mirounga.The two species, the northern elephant seal (M. angustirostris) and the southern elephant seal (M. leonina), were both hunted to the brink of extinction by the end of the 19th century, but their numbers have since recovered.. "Parental behavior", pp. Walruses and hooded seals are unique among ice-breeding species in that they have pronounced sexual dimorphism in favor of males. Solitary foraging species usually exploit coastal waters, bays and rivers. [107] Species that breed on land are usually polygynous, as females gather in large aggregations and males are able to mate with them as well as defend them from rivals. [69], Before diving, pinnipeds typically exhale to empty their lungs of half the air[70] and then close their nostrils and throat cartilages to protect the trachea. The northern fur seal pants to help stay cool, while monk seals often dig holes in the sand to expose cooler layers to rest in. When contracted, the pupil is typically pear-shaped, although the bearded seal's is more diagonal. [24] Phocids are known to have existed for at least 15 million years,[13] and molecular evidence supports a divergence of the Monachinae and Phocinae lineages 22 Mya. Several species are known to migrate vast distances, particularly in response to extreme environmental changes, like El Niño or changes in ice cover. They have a layer of fat, or blubber, under the skin to keep warm in the cold water, and, other than the walrus, all species are covered in fur. Leopard seal vs sea lion size. They can also create somewhat musical sounds with their inflated throats. [176], Some species have become so numerous that they conflict with local people. [181] Wildlife officials have unsuccessfully attempted to ward off the sea lions using bombs, rubber bullets and bean bags. [88] Traveling seals may use various features of their environment to reach their destination including geomagnetic fields, water and wind currents, the position of the sun and moon and the taste and temperature of the water. [7] Pinnipeds belong to the order Carnivora and the suborder Caniformia (known as dog-like carnivorans). Berta, A. [135] Male walruses may help inexperienced young as they learn to swim, and have even been recorded caring for orphans. [150] They demonstrate the ability to understand simple syntax and commands when taught an artificial sign language, though they only rarely used the signs semantically or logically. [116] Individuals also return to the same territorial site each breeding season. Seals produce a number of vocalizations, notably the barks of California sea lions, the gong-like calls of walruses and the complex songs of Weddell seals. [117] Male vocals are usually of lower frequencies than those of the females. [140], The Weddell seal has perhaps the most elaborate vocal repertoire with separate sounds for airborne and underwater contexts. Yeah, I know I change my name every now and then. 923–931 in Perrin, Würsig and, Mesnick, S. L.; Ralls, K. "Mating systems", pp. A.; Gregg, J. D. "Communication in marine mammals", pp. The leopard seal also referred to as the sea leopard, is the second largest species of seal in the Antarctic (after the southern elephant seal). The Callorhinus lineage split earlier at 16 mya. Ranked as the third largest pinniped (seal) in the world, after the walrus and the elephant seal, the leopard seal is an amazing creature that can be both fascinating and dangerous at the same time. [127] Lactation in otariids may last 6–11 months; in the Galápagos fur seal it can last as long as 3 years. This is an epic Seal vs. Shark Battle in The Pacific Ocean off of Northern California on April 18, 2015. 542–546 in Perrin, Würsig and, Kastelein, R. A. Francis Galton noted in his landmark paper on domestication that seals were a spectacular example of an animal that would most likely never be domesticated despite their friendliness and desire for comfort due to the fact that they serve no practical use for humans. [2] The common name "seal" originates from the Old English word seolh, which is in turn derived from the Proto-Germanic *selkhaz. They can also dive 1,259–4,100 m (4,131–13,451 ft) and for as long as 62 minutes. [61] By holding their vibrissae steady, pinnipeds are able to maximize their detection ability. The leopard seal (Hydrurga leptonyx), also referred to as the sea leopard, is the second largest species of seal in the Antarctic (after the southern elephant seal). And, When the leopard seal was not looking, The orca uses it’s massive jaws to take a huge bite out of the leopard seal’s body. [152] In 1971, a captive harbor seal named Hoover was trained to imitate human words, phrases and laughter. "Pinnipedia, overview", pp. [91], Pinnipeds have lifespans averaging 25–30 years. [33] Land-breeding pinnipeds tend to mate on islands where there are fewer terrestrial predators. [129] Typically, single pups are born;[127] twins are uncommon and have high mortality rates. [101], Pinnipeds lessen the chance of predation by gathering in groups. [127] All species go through delayed implantation, wherein the embryo remains in suspended development for weeks or months before it is implanted in the uterus. The two species, the northern elephant seal and the southern elephant seal, were both hunted to the brink of extinction by the end of the 19th century, but their numbers have since recovered. While they are often food for sharks, they are also deadly predators, especially in the cold climates like Antarctica. These are important for detecting their prey on the muddy sea floor. [112][113], Younger or subdominant male pinnipeds may attempt to achieve reproductive success in other ways. This distinction is being questioned as indigenous people are using more modern weaponry and mechanized transport to hunt with, and are selling seal products in the marketplace. [104], Interspecific predation among pinnipeds does occur. [157] The Moche people of ancient Peru worshipped the sea and its animals, and often depicted sea lions in their art. They have streamlined bodies and four limbs that are modified into flippers. In addition, harbor seals may visit estuaries, lakes and rivers and sometimes stay as long as a year. In addition, the walrus lacks external ear flaps. She is depicted as a mermaid, occasionally with a seal's lower body. The Baikal seal is the only freshwater species, though some ringed seals live in freshwater lakes in Russia close to the Baltic sea. Here, fierce hunters like leopard seals attack and kill penguins. Though not as fast in the water as dolphins, seals are more flexible and agile. In addition, sea lions are known to "ride" waves, which probably helps them decrease their energy usage. The most common pinniped species kept in captivity is the California sea lion as it is both easy to train and adaptable. In air, hearing is somewhat reduced in pinnipeds compared to many terrestrial mammals. The elephant seal first tries to bite the orca’s face and succeeds, making the killer whale let go. Seals range in size from the 1 m (3 ft 3 in) and 45 kg (99 lb) Baikal seal to the 5 m (16 ft) and 3,200 kg (7,100 lb) southern elephant seal male, which is also the largest member of the order Carnivora. [113][119] In some species, including elephant seals and grey seals, males will try to lay claim to the desired females and defend them from rivals. Leopard seals typically target crabeater pups, which form an important part of their diet from November to January. [138], Pinnipeds can produce a number of vocalizations such as barks, grunts, rasps, rattles, growls, creaks, warbles, trills, chirps, chugs, clicks and whistles. In species that live in shallow water, such as harbor seals and California sea lions, dilation varies little, while the deep-diving elephant seals have much greater variation. [48][49] This is because it feeds on immobile bottom dwelling mollusks and hence does not need acute vision. Animal Face Off Wiki is a FANDOM TV Community. The northern elephant seal has one of the longest recorded migration distances for a mammal, at 18,000–21,000 km (11,000–13,000 mi). However, its limbs and shoulders were more robust and Puijila likely had been a quadrupedal swimmer—retaining a form of aquatic locomotion that gave rise to the major swimming types employed by modern pinnipeds. [57] Although pinnipeds have a fairly good sense of smell on land,[58] it is useless underwater as their nostrils are closed. Their bodies are long and slender, and their heads appear to be almost too large for their serpent-like bodies. The vibrissa's angle relative to the flow, not the shape, however, seems to be the most important factor. 861–66 in Perrin, Würsig and, Berta, A. Their bodies are long and slender and their heads appear to be almost a little too large for their thin serpent like bodies. This has been met with controversy and debate. Pinnipeds (pronounced /ˈpɪnɪˌpɛdz/), commonly known as seals,[a] are a widely distributed and diverse clade of carnivorous, fin-footed, semiaquatic marine mammals. Even though that these two animals will never meet each other in the wild. But the elephant seal fights back, something most prey never does. [166], Commercial sealing was historically just as important an industry as whaling. [14] Five genera and seven species (one now extinct) of sea lion are known to exist, while two genera and nine species of fur seal exist. These males commonly disrupt the copulations of their subordinates while they themselves can mount without inference. These pollutants can cause gastrointestinal cancers, decreased reproductivity and greater vulnerability to infectious diseases. [48] A seal's eye is adapted for seeing both underwater and in air. [103] Arctic seals use more breathing holes per individual, appear more restless when hauled out, and rarely defecate on the ice. This helps them see in low-light conditions. In addition, since ice is less stable than solid land, breeding sites change location each year, and males are unable to predict where females will stay during the breeding season. [87], Pinnipeds have an amphibious lifestyle; they spend most of their lives in the water, but haul out to mate, raise young, molt, rest, thermoregulate or escape from aquatic predators. "Distribution", pp. [113] These are also maintained by vocalizations. Its long-term memory allows it to perform a trick after at least three months of non-performance. [13], Phocids are known as true or "earless" seals. Their mystacial vibrissae have ten times the innervation of terrestrial mammals, allowing them to effectively detect vibrations in the water. Female leopard seals, the larger of the two sexes, can grow up to 590 kg (1,300 pounds) and 3.8m meters (10 feet) long. [16], Odobenidae consists of only one living member: the modern walrus. Pinnipeds belong to the order Carnivora and their closest living relatives are bears and the superfamily of musteloids (weasels, raccoons, skunks, and red pandas), having diverged about 50 million years ago. The southern elephant seal, which is had significantly larger bulls than the northern elephant seal, is the largest marine mammal that is not a cetacean. Leopard seals can live up to 26 years in the wild. [86] Polar-living species haul out on to both fast ice and drift ice. The deep split between the lineages of Erignathus and Cystophora 17 Mya suggests that the phocines migrated eastward and northward from the North Atlantic. This animal is easily distinguished from other extant pinnipeds by its larger size (exceeded only by the elephant seals), nearly hairless skin and long upper canines, known as tusks. Elephant seals stay at sea 8–10 months a year and migrate between breeding and molting sites. In particular, northern elephant seal pups gain 4 kg (9 lb) each day before they are weaned. [151] In 2011, a captive California sea lion named Ronan was recorded bobbing its head in synchrony to musical rhythms. In water, true seals swim by moving their hind-flippers and lower body from side to side. [42], Pinnipeds have two pairs of flippers on the front and back, the fore-flippers and hind-flippers. Photographer - Jan Roletto, NOAA. 585–588 in Perrin, Würsig and Thewissen (2009), Duffield, D. A. [5] American zoologist Joel Asaph Allen reviewed the world's pinnipeds in an 1880 monograph, History of North American pinnipeds, a monograph of the walruses, sea-lions, sea-bears and seals of North America. Besides hunting, pinnipeds also face threats from accidental trapping, marine pollution, and conflicts with local people. Facebook; Twitter; Tumblr; LinkedIn; MySpace; Email; Go to. Click on a box to hear the audio. [44] Compared to terrestrial carnivorans, the fore-limbs of otariids are reduced in length, which gives the locomotor muscles at the shoulder and elbow joints greater mechanical advantage;[43] the hind-flippers serve as stabilizers. Bulls of the northern elephant seal typically weigh in at 1500-2300 kg and have a length of 4-5 meters. Phocids such as elephant seals, grey seals and hooded seals remain on land or ice and fast during their relatively short lactation period–four days for the hooded seal and five weeks for elephant seals. [167] Conversely, the Mediterranean monk seal was extirpated from much of its former range, which stretched from the Mediterranean to the Black Sea and northwest Africa, and only remains in the northeastern Mediterranean and some parts of northwest Africa. Even some fully furred species (particularly sea lions) are less haired than most land mammals. [95] While most species are generalist and opportunistic feeders, a few are specialists. [41] As in most marine mammals, the kidneys are divided into small lobes and can effectively absorb water and filter out excess salt. [101], The mating system of pinnipeds varies from extreme polygyny to serial monogamy. Otariids rely on the movements of their heads and necks more than their hind-flippers during terrestrial locomotion. Females typically mature earlier than males. "Extinction, specific", pp. The genera Phoca and Pusa could have arisen when a phocine lineage traveled from the Paratethys Sea to the Arctic Basin and subsequently went eastward. These animals rely on their well-developed fore-flippers to propel themselves through the water. [128] Pups of most species are born precocial. They are unintentionally caught in fishing nets by commercial fisheries and accidentally swallow fishing hooks. It has since recolonized much of its historic range, but has a population bottleneck. The lineage of the modern walrus may have spread from the North Pacific to the Caribbean (via the Central American Seaway) 8–5 Mya and subsequently made it to the North Atlantic and returned to the North Pacific via the Arctic 1 mya. Navy officials say that the sea lions can do this in seconds, before the enemy realizes what happened. [177][178] Sea lions also conflict with fisherman since both depend on the same fish stocks. The pattern is similar to that of the famous big cat, though the seal's coat is gray rather than golden in color. They also lack supraorbital processes on the frontal and have underdeveloped calcaneal tubers. The Elephant seal goes back on the ice.
