The Info List - Northern Elephant Seal

--- Advertisement ---

The northern elephant seal (Mirounga angustirostris) is one of two species of elephant seal (the other is the southern elephant seal). It is a member of the family Phocidae
("true seals"). Elephant seals derive their name from their great size and from the male's large proboscis, which is used in making extraordinarily loud roaring noises, especially during the mating competition. Sexual dimorphism
Sexual dimorphism
in size is great: The males can grow to 14 ft (4 m) and 5,000 lb (2,300 kg), while the females grow to 11 ft (3 m) and 1,400 lb (640 kg). Correspondingly, the mating system is highly polygynous; a successful male is able to impregnate up to 50 females in one season.

The huge male northern elephant seal typically weighs 1,500–2,300 kg (3,300–5,100 lb) and measures 4–5 m (13–16 ft), although some males can weigh up to 3,700 kg (8,200 lb).[2] Females are much smaller and can range from 400 to 900 kg (880 to 1,980 lb) in weight, or roughly a third of the male's bulk, and measure from 2.5 to 3.6 m (8.2 to 11.8 ft).[3] The bull Southern Elephant Seals are, on average, larger than those in the Northern species but the females in both are around the same size, indicating the even higher level of sexual dimorphism in the Southern species.[4] Both adult and juvenile elephant seals are bar-skinned[discuss] and black before molting. After molting, they generally have a silver to dark gray coat that fades to brownish-yellow and tan. Adult males have hairless necks and chests speckled with pink, white and light brown. Pups are mostly black at birth and molt to a silver gray after weaning.[citation needed] The eyes are large, round and black. The width of the eyes and a high concentration of low light pigments suggest sight plays an important role in the capture of prey. Like all seals, elephant seals have atrophied hind limbs whose underdeveloped ends form the tail and tail fin. Each of the "feet" can deploy five long, webbed fingers. This agile, dual palm is used to propel water. The pectoral fins are used little while swimming.[citation needed] While their hind limbs are unfit for locomotion on land, elephant seals use their fins as support to propel their bodies. They are able to propel themselves quickly (as fast as 8 km/h) in this way for short-distance travel, to return to water, catch up with a female or chase an intruder.[citation needed] Like other seals, elephant seals' bloodstreams are adapted to the cold in which a mixture of small veins surrounds arteries capturing heat from them. This structure is present in extremities such as the hindlimbs.[citation needed] A unique characteristic of the northern elephant seal is that it has developed the ability to store oxygenated red blood cells within its spleen. In a 2004 study researchers used MRI
to observe physiological changes of the spleens of 5 seal pups during simulated dives. By 3 minutes, the spleens on average contracted to a fifth of their original size, indicating a dive-related sympathetic contraction of the spleen. Also, a delay was observed between contraction of the spleen and increased hematocrit within the circulating blood, and attributed to the hepatic sinus. This fluid-filled structure is initially expanded due to the rush of RBC from the spleen and slowly releases the red blood cells into the circulatory system via a muscular vena caval sphincter found on the cranial aspect of the diaphragm. This ability to slowly introduce RBC into the blood stream is likely to prevent any harmful effects caused by a rapid increase in hematocrit.[5] Range and ecology[edit]

Mother and pup, Piedras Blancas

The northern elephant seal lives in the eastern Pacific Ocean. They spend most of their time at sea, and usually only come to land to give birth, breed, and molt. These activities occur at rookeries that are located on offshore islands or remote mainland beaches. The majority of these rookeries are in California and northern Baja California, ranging from Point Reyes
Point Reyes
National Seashore, California to Isla Natividad, Mexico.[6] Significant breeding colonies exist at Channel Islands, Año Nuevo State Reserve, Piedras Blancas Light, Morro Bay State Park and the Farallon Islands
Farallon Islands
in the US,[7] and Isla Guadalupe, Isla Benito del Este and Isla Cedros
Isla Cedros
in Mexico.[7] In recent decades the breeding range has extended northwards. In 1976 the first pup was found on Point Reyes
Point Reyes
in 1976 and a breeding colony established there in 1981.[8] Since the mid-1990s some breeding has been observed at Castle Rock in Northern California and Shell Island off Oregon[9] and in January 2009, the first elephant seal births were recorded in British Columbia at Race Rocks.[10] The California breeding population is now demographically isolated from the population in Baja California.[7] Northern elephant seals exhibit extreme sexual dimorphism in their feeding behaviours. When the males leave their rookeries, they migrate northwards to their feeding grounds along the continental shelf from Washington to the western Aleutians in Alaska.[11][12] The males mostly feed on benthic organisms on the ocean floor.[11] When the females leave their rookeries, they head north or west into open ocean, and forage across a large area in the northeastern Pacific.[11] They have been recorded as far west as Hawaii.[11] Female elephant seals feed mainly on pelagic organisms in the water column.[11] Vagrant elephant seals possibly appear on tropical regions such as at Mariana Islands.[13] Historical occurrences of elephant seal presence, residential or occasional, in western North Pacific are fairly unknown. There have been two records of vagrants visiting to Japanese coasts; a male on Niijima
in 1989[14] (reference introducing a visit by a North Pacific right whale
North Pacific right whale
in 2011), and a young seal on beaches in Hasama, Tateyama in 2001[15] (where another right whale was seen in 2000). A 2.5 meter female was found on Sanze beach, Tsuruoka, Yamagata in October 2017, making it the first record from Sea of Japan. This individual was severely weaken but showing signs of recovery after receiving medications at Kamo Aquarium, and the aquarium is discussing whether or not to release her.[16] Some individuals have been observed on the coast of northeast Asia. Certain individuals established haul-out sites at the Commander Islands
Commander Islands
in the early 2000s; however, due to aggressive interactions with local Steller sea lions, long-term colonization is not expected.[17][18]

Female elephant seals forage in the open ocean, while male elephant seals forage along the continental shelf.[11] Males usually dive straight down to the ocean floor and stay at the bottom foraging for benthic prey.[11] The females hunt for pelagic prey in the open ocean, and dive deeper (up to 1000 m) and stay down longer than the males.[11] Northern elephant seals eat a variety of prey, including pelagic, deep-water squid, Pacific hake, pelagic crustaceans, sharks, rays, and ratfish.[12][19] Octopoteuthis deletron
Octopoteuthis deletron
squid are a common prey item, one study found this species in the stomachs of 58% of individuals sampled off the coast of California.[20] A female northern elephant seal was documented in 2013 by a deep sea camera at a depth of 894 m (2,933 ft), where it consumed a Pacific hagfish, slurping it up from the ocean floor. The event was reported by a Ukrainian boy named Kirill Dudko, who further reported the find to scientists in Canada.[21] Elephant seals do not need to drink, as they get their water from food and metabolism of fats. While hunting in the dark depths, elephant seals seem to locate their prey at least partly by vision; the bioluminescence of some prey animals can facilitate their capture. Elephant seals do not have a developed a system of echolocation in the manner of cetaceans, but their vibrissae, which are sensitive to vibrations, are assumed to play a role in search of food. Males and females differ in diving behavior. Males tend to hug the continental shelf while making deep dives and forage along the bottom,[11] while females have more jagged routes and forage in the open ocean.[11] Males return to the same feeding ground every year, while females have less predictable feeding migrations. Elephant seals are prey for killer whales and white sharks. Both are most likely to hunt pups, and seldom hunt large bull elephant seals, but have taken seals of all ages. The shark, when hunting adults, is most likely to ambush a seal with a damaging bite and wait until it is weakened by blood loss to finish the kill.[22] Social behavior and reproduction[edit]

Male elephant seals fighting for mates

Northern elephant seals return to their terrestrial breeding ground in December and January, with the bulls arriving first. The bulls haul out on isolated or otherwise protected beaches, typically on islands or very remote mainland locations. It is important that these beach areas offer protection from the winter storms and high surf wave action.[23] The bulls engage in fights of supremacy to determine which few bulls will achieve a harem.[24][25] After the males have arrived to the beach, the females arrive to give birth. Females fast for five weeks and nurse their single pup for four weeks; in the last few days of lactation, females come into estrus and mate.[26] In this polygynous society, a high-ranking bull can have a harem of 30–100 cows, depending on his size and strength. Males unable to establish harems will wait on the periphery, and will try to mount nearby females.[24] Dominant bulls will disrupt copulations of lower-ranking bulls.[24] They can mount females without interference, but commonly break off to chase off rivals.[24] While fights are not usually to the death, they are brutal and often with significant bloodshed and injury; however, in many cases of mismatched opponents, the younger, less capable males are simply chased away, often to upland dunes. In a lifetime, a successful bull could easily sire over 500 pups. Most copulations in a breeding colony are done by only a small number of males and the rest may never be able to mate with a female.[25] Pups are sometimes crushed during battles between bulls.[23][25]

Three pups are nursing from a single adult female: Female elephant seals deliver only one pup; the two other may have wandered away from their mothers and gotten lost. In this situation, no pup would get enough milk.

After arrival on shore, males fast for three months, and females fast for five weeks during mating and when nursing their pups. The gestation period is about 11 months. Sometimes, a female can become very aggressive after giving birth and will defend her pup from other females.[27] Such aggression is more common in crowded beaches.[27] While most females nurse their own pups and reject nursings from alien pups, some do accept alien pups with their own.[23][26] An orphaned pup may try to find another female to suckle and some are adopted, at least on Año Nuevo Island.[23][26] Pups nurse about four weeks and are weaned abruptly before being abandoned by their mother, who heads out to sea within a few days. Left alone, weaned pups will gather into groups and stay on shore for 12 more weeks. The pups learn how to swim in the surf and eventually swim farther to forage. Thus, their first long journey at sea begins. Elephant seals communicate though various means. Males will threaten each other with the snort, a sound caused by expelling air though their probosces, and the clap-trap, a loud, clapping sound comparable to the sound of a diesel engine.[28] Pups will vocalize when stressed or when prodding their mothers to allow them to suckle. Females make an unpulsed attraction call when responding to their young, and a harsh, pulsed call when threatened by other females, males or alien pups.[28] Elephant seals produce low-frequency sounds, both substrate-borne and air-borne. These sounds help maintain social hierarchy in crowded or noisy environments and reduce energy consumption when fasting.[28] History and status[edit]

The northern elephant seal population was estimated to be 171,000 in 2005.[1]

Beginning in the 18th century, northern elephant seals were hunted extensively, almost to extinction by the end of the 19th century,[1] being prized for oil made from their blubber, and the population may have fallen as low as only 20 individuals.[1] In 1874, Charles Melville Scammon recorded in Marine Mammals of the Northwestern Coast of America, that an 18-ft-long bull caught on Santa Barbara Island yielded 210 gallons of oil.[29] They were thought to be extinct in 1884 until a remnant population of eight individuals was discovered on Guadalupe Island
Guadalupe Island
in 1892 by a Smithsonian expedition, who promptly killed seven of the eight for their collections.[30] The elephant seals managed to survive, and were finally protected by the Mexican government in 1922. Since the early 20th century, they have been protected by law in both Mexico and in the United States. Subsequently, the U.S. protection was strengthened after passage of the Marine Mammal
Protection Act of 1972, and numbers have now recovered to over 100,000.[citation needed] Nevertheless, a genetic bottleneck is present in the existing population, which could make it more susceptible to disease and pollution.[31][32] In California, the population is continuing to grow at around 6% per year, and new colonies are being established; they are now probably limited mostly by the availability of haul-out space. Their breeding was probably restricted to islands, before large carnivores were exterminated or prevented from reaching the side of the ocean.[33] Numbers can be adversely affected by El Niño
El Niño
events and the resultant weather conditions, and the 1997–98 El Niño
El Niño
may have caused the loss of about 80% of that year's pups. Presently, the northern elephant seal is protected under the federal Marine Mammal Protection Act and has a fully protected status under California law.[citation needed] Populations of rookery sites in California have increased during the past century.[1] At Año Nuevo State Park, for example, no individuals were observed whatsoever until 1955; the first pup born there was observed in the early 1960s. Currently, thousands of pups are born every year at Año Nuevo, on both the island and mainland. The growth of the site near San Simeon has proved even more spectacular; no animals were there prior to 1990. Currently, the San Simeon site hosts more breeding animals than Año Nuevo State Park
Año Nuevo State Park
during winter season.[citation needed] References[edit]
