The Info List - California Sea Lion

The California sea lion
California sea lion
( Zalophus
californianus) is a coastal eared seal native to western North America. It is one of six species of sea lion. Its natural habitat ranges from southeast Alaska to central Mexico, including the Gulf of California. Sea lions are sexually dimorphic; males are larger than females, and have a thicker neck, and protruding sagittal crest. They mainly haul-out on sandy or rocky beaches, but they also frequent manmade environments such as marinas and wharves. Sea lions feed on a number of species of fish and squid, and are preyed on by orcas and white sharks. California sea lions have a polygynous breeding pattern. From May to August, males establish territories and try to attract females with which to mate. Females are free to move in between territories, and are not coerced by males. Mothers nurse their pups in between foraging trips. Sea lions communicate with numerous vocalizations, notably with barks and mother-pup contact calls. Outside their breeding season, sea lions spend much of their time at sea, but they come to shore to molt. Sea lions are particularly intelligent, can be trained to perform various tasks and display limited fear of humans if accustomed to them. Because of this, California sea lions are a popular choice for public display in zoos, circuses and oceanariums, and are trained by the United States Navy for certain military operations. The International Union for Conservation of Nature
International Union for Conservation of Nature
(IUCN) lists the species as Least Concern
Least Concern
due to its abundance. To protect fish, the US states of Oregon
and Washington engage in annual kill quotas of sea lions.

Taxonomy[edit] Lithography by Joseph Smit. The California sea lion
California sea lion
was described by René Primevère Lesson, a French naturalist, in 1828. It is grouped with other sea lions and fur seals in the family Otariidae. Otariids, also known as eared seals, differ from true seals in having external ear flaps, and proportionately larger foreflippers and pectoral muscles. Along with the Galapagos sea lion
Galapagos sea lion
and the extinct Japanese sea lion, the California sea lion
California sea lion
belongs to the genus Zalophus, which derives from the Greek words za, meaning "intensive," and lophus, meaning "crest."[2] This refers to the protruding sagittal crest of the males, which distinguishes members of the genus.[3] Traditionally, the Galapagos sea lion
Galapagos sea lion
and Japanese sea lion
Japanese sea lion
were classified as subspecies of the California sea lion. However, a genetic study in 2007 found that all three are in fact separate species.[4] The lineages of the California and Japanese sea lion appear to have split off 2.2 million years ago during the Pliocene.[5] The California sea lion

in its greater sexual dimorphism.[3] The Steller sea lion

is the closest extant relative of the Zalophus
sea lions, being a sister taxon.[6]

Appearance, physiology, and movement[edit] California sea lion
California sea lion
skeleton Being sexually dimorphic, California sea lions differ in size, shape, and coloration between the sexes. Males are typically around 2.4 m (7.9 ft) long and weigh up to 350 kg (770 lb), while females are typically around 1.8 m (5.9 ft) and weigh up to 100 kg (220 lb).[3] Females and juveniles have a tawny brown pelage,[3] although they may be temporarily light gray or silver after molting.[7] The pelage of adult males can be anywhere from light brown to black, but is typically dark brown.[3] The face of adult males may also be light tan in some areas. Pups have a black or dark brown pelage at birth.[7] Although the species has a slender build, adult males have robust necks, chests, and shoulders.[7] Adult males also have a protruding crest which gives them a "high, domed forehead";[8] it is tufted with white hairs.[3] They also have manes, which are less developed than those of adult male South American and Steller sea lions.[8] Both sexes have long, narrow muzzles.[7] As an otariid, the California sea lion
California sea lion
relies on its foreflippers to propel itself when swimming. This form of aquatic locomotion, along with its streamlined body, effectively reduces drag underwater. Its foreflipper movement is not continuous; the animal glides in between each stroke.[9] The flexibility of its spine allows the sea lion to bend its neck backwards far enough to reach its hindflippers. This allows the animal to make dorsal turns and maintain a streamlined posture.[10] When moving on land, the sea lion is able to turn its hindflippers forward and walk on all fours. It moves the foreflippers in a transverse, rather than a sagittal, fashion. In addition, it relies on movements of its head and neck more than its hindflippers for terrestrial locomotion.[11] Sea lions may travel at speeds of around 10.8 km/h (6.7 mph),[12] and can dive at depths of 274 m (899 ft) and for up to 9.9 minutes, though most dives are typically 80 m (260 ft) and last less than 3 minutes.[13]

swimming underwater Sea lions have color vision, though it is limited to the blue-green area of the color spectrum. This is likely an adaptation for living in marine coastal habitats.[14] Sea lions have fairly acute underwater hearing, with a hearing range of 0.4–32 kHz.[15] Sea lions rely on their whiskers or vibrissae for touch and detection of vibrations underwater. Compared to the harbor seal, the California sea lion's vibrissae are smoother and less specialized and thus perform less when following hydrodynamic trails, although they still perform well.[16]

Ecology[edit] Range and habitat[edit] Sea lion
Sea lion

California sea lion
ranges along the western coast and islands of North America, from southeast Alaska to central Mexico. Mitochondrial DNA sequences in 2009 have identified five distinct California sea lion populations: the U.S. or Pacific Temperate stock, the Western Baja California or Pacific Tropical stock, and the Southern, Central, and Northern Gulf of California
Gulf of California
stocks.[6] The U.S. stock breeds mainly in the Channel Islands, although some breeding sites may be established in northern California, and females are now commonly found there.[1] The Western Baja California stock mainly breeds near Punta Eugenia
Punta Eugenia
and at Isla Santa Margarita. The above-mentioned stocks are separated by the Ensenada Front. The stocks of the Gulf of California
Gulf of California
live in the shallow waters of the north (Northern stock), the tidal islands near the center (Central stock), and the mouth of the bay (Southern stock). The stock status of the sea lions at the deep waters of the central bay has not been analyzed.[6] Vagrants can reach western north pacific such as on Commander Islands.[17] Although several otariinae have been recorded around Japanese archipelago in recent years, their exact origins are unclear.[18]

Sea lions in Santa Cruz, California During the breeding season, sea lions gather on both sandy and rocky shores. On warm days, they lie closer to the water. At night or in cool weather, they travel farther inland or to higher elevations.[7] Non-breeding individuals may gather at marinas, wharves, or even navigational buoys. California sea lions can also live in fresh water for periods of time, such as near Bonneville Dam, nearly 150 miles up the Columbia River.[19] In 2004 a healthy sea lion was found sitting on a road in Merced County, California, almost a hundred miles upstream from the San Francisco Bay
San Francisco Bay
and half a mile from the San Joaquin River.[20]

Diet and predation[edit] California sea lions feed on a wide variety of seafood, mainly squid and fish, and sometimes clams. Commonly eaten fish and squid species include salmon, hake, Pacific whiting, anchovy, herring, rockfish, lamprey, dogfish, and market squid.[21] They mostly forage near mainland coastlines, the continental shelf, and seamounts. They may also search along the ocean bottom.[7] California sea lions may eat alone or in small to large groups, depending on the amount of food available. They sometimes cooperate with other predators, such as dolphins, porpoises, and seabirds, when hunting large schools of fish.[22] Sea lions sometimes follow dolphins and exploit their hunting efforts.[3] Adult females feed between 10–100 km (6.2–62.1 mi) from shore.[12] Males may forage as far as 450 km (280 mi) from shore when water temperatures rise.[23] They also have learned to feed on steelhead and salmon below fish ladders at Bonneville Dam
Bonneville Dam
and at other locations where fish must queue in order to pass through dams and locks that block their passage. Sea lions are preyed on by killer whales and large sharks. At Monterey Bay, California sea lions appear to be the more common food items for transient mammal-eating killer whale pods.[24] The sea lions may respond to the dorsal fin of a killer whale and remain vigilant, even when encountering resident fish-eating pods.[25] Sea lions are also common prey for white sharks. They have been found with scars made by attacks from both white sharks and shortfin mako sharks. Sharks attack sea lions by ambushing them while they are resting at the surface.[26] Sea lions that are attacked in the hindquarters are more likely to survive and make it to the shore.[27]

Life history[edit] Reproductive behavior and parenting[edit] Sea lion
Sea lion
rookery California sea lions breed gregariously between May and August, when they arrive at their breeding rookeries. When establishing a territory, the males will try to increase their chances of reproducing by staying on the rookery for as long as possible. During this time, they will fast, relying on a thick layer of fat called blubber for energy. Size and patience allow a male to defend his territory more effectively; the bigger the male, the more blubber he can store and the longer he can wait. A male sea lion usually keeps his territory for around 27 days. Females have long parturition intervals, and thus the males do not establish their territories until after the females give birth. Most fights occur during this time. After this, the males rely on ritualized displays (vocalizations, head-shaking, stares, bluff lunges, and so on) to maintain their territorial boundaries. Since temperatures can reach over 30 °C (86 °F) during this time, males must include water within their territories. Some territories are underwater, particularly those near steep cliffs.[28] Sea lions that fail to establish a territory are driven out to sea or gather at a nearby beach.[3]

mother with pup Before mating begins, females gather into "milling" groups of 2–20 individuals. The females in these groups will mount each other as well as the males. These groups begin to disintegrate as the females begin to mate.[3] The territorial and mating system of the California sea lion
California sea lion
has been described as similar to a lek system, as females appear to choose their mates while moving though different territories.[29] They avoid males that are too aggressive or energetic. Males are usually unable to prevent females from leaving their territories,[3] particularly in water.[30] Mating may occur outside the rookeries, between non-territorial males and females, as the latter move to and from the mating site. In some rookeries, copulation may be monopolized by a few males, while at others, a single male may sire no more than four pups.[30] Female California sea lions have a 12-month reproductive cycle, consisting of a 9-month actual gestation and a 3-month delayed implantation of the fertilized egg before giving birth in June or July. Interbirth intervals are particularly long for this species, being 21 days for sea lions off California and more than 30 days for sea lions in the Gulf of California.[30] Females remain with their pups on shore for 10 days and nurse them. After this, females will go on foraging trips lasting as long as three days, returning to nurse their pups for up to a day. Pups left on shore tend to gather in nurseries to socialize and play.[7] When returning from a trip, females call their pups with distinctive calls to which the pups will reply in kind. A mother and pup can distinguish each other's calls from those of other mothers and pups. At first, reunions largely depend on the efforts of the mothers. However, as pups get older, they get more involved in reunions.[31] Older pups may sometimes join their mothers during their foraging trips.[7] Adult male California sea lions play no role in raising pups, but they do take more interest in them than adult males of other otariid species; they have even been observed to help shield swimming pups from predators.[32] Pups are weaned by a year but can continue to suckle for another year.[3]

Communication[edit] Play media Barking sea lions pursuing a boat California sea lions communicate with a range of vocalizations. The most commonly used one is their characteristic bark. Territorial males are the loudest and most continuous callers, and barks are produced constantly during the peak of the breeding season. Sea lions bark especially rapidly when excited. The barks of territorial and non-territorial males sound similar, although those of the former are deeper. Males may bark when threatening other males or during courtship. The only other vocalization made by territorial males is a "prolonged hoarse grunt sound" made when an individual is startled by a human. This vocalization is also made by groups of non-reproductive males.[33] Female sea lions are less vocal. Their barks, high-pitched and shorter than those made by males, are used in aggressive situations. Other aggressive vocalizations given by females include the "squeal", the "belch", and the "growl". The sound a female sea lion gives when calling her pups is called a "pup-attraction call", described as "loud" and "brawling". Pups respond with a "mother-response call", which is similar in structure. Pups will also bleat or bark when playing or in distress.[33] California sea lions can produce vocalizations underwater. These include "whinny" sounds, barks, buzzings, and clicks.[34]

Nonbreeding activities[edit] Outside the breeding season, males migrate to the northern ends of the species range to feed, while females forage near the breeding rookeries.[3] Sea lions can stay at sea for as long as two weeks at a time. They make continuous dives, returning to the surface to rest. Sea lions may travel alone or in groups while at sea and haul-out between each sea trip. Adult females and juveniles molt in autumn and winter; adult males molt in January and February. Gulf of California sea lions do not migrate; they stay in the Gulf year-round.[30]

Intelligence and trainability[edit] Zak, a 375 lb (170 kg) Navy sea lion leaps back into the boat after a harbor-patrol training mission. Marine biologist Ronald J. Schusterman and his research associates have studied sea lions' cognitive ability. They have discovered that sea lions are able to recognize relationships between stimuli based on similar functions or connections made with their peers, rather than only the stimuli's common features.[35] Sea lions have demonstrated the ability to understand simple syntax and commands when taught an artificial sign language. However, the sea lions rarely used the signs semantically or logically.[36] In 2011, a California sea lion named "Ronan" was recorded bobbing her head in synchronization to musical rhythms.[37] This "rhythmic entrainment" was previously seen only in humans, parrots and other birds possessing vocal mimicry.[38]

Play media Captive sea lion performing A California sea lion

at Central Park Zoo. It has climbed to the edge of its tank awaiting feeding, showing awareness of its regular feeding time. Because of their intelligence and trainability, California sea lions have been used by circuses and marine mammal parks to perform various tricks such as throwing and catching balls on their noses, running up ladders, or honking horns in a musical fashion. Trainers reward their animals with fish, which motivates them to perform. For ball balancing, trainers toss a ball at a sea lion so it may accidentally balance it or hold the ball on its nose, thereby gaining an understanding of what to do. A sea lion may go through a year of training before performing a behavior for the public. However, its memory allows it to perform a behavior even after three months of resting.[32] Some organizations, such as the Humane Society of the United States and World Animal
Protection, object to using sea lions and other marine mammals for entertainment, claiming the tricks are "exaggerated variations of their natural behaviors" and distract the audience from the animal's unnatural environment.[39] Less entertainment-oriented zoos may still encourage animal play by throwing fish at animals in different directions and providing play equipment.[40] The California sea lion
California sea lion
is used in military applications by the U.S. Navy Marine Mammal
Program, including detecting naval mines and enemy divers. In the Persian Gulf, the animals can swim behind divers approaching a US naval ship and attach a clamp with a rope to the diver's leg. Navy officials say the sea lions can do this in seconds, before the enemy realizes what happened.[41] Organizations like PETA
believe that such operations put the animals in danger.[42] However, the Navy insists that the sea lions are removed once their mission is complete.[43]

Status[edit] Hundreds of California sea lions bask on Pier 39 in San Francisco, where they are welcomed as a tourist attraction. The IUCN lists the California sea lion
California sea lion
as Least Concern
Least Concern
due to "its large and increasing population size."[1] The estimated population is 238,000–241,000 for the U.S. or Pacific Temperate stock, 75,000–85,000 for the Western Baja California or Pacific Tropical stock, and 31,393 for the population in the Gulf of California.[6] Off the Pacific coast of the United States, sea lions are so numerous that they are close to carrying capacity, while the Gulf of California
Gulf of California
population declined by 20% by 2008. Sea lions may be killed when in conflict with fishermen, by poaching, and by entanglements in man-made garbage. They are also threatened by pollutants like DDT
and PCB which accumulate in the marine food chain.[1]

Shooting sea lions, ca. 1870s In the United States, the California sea lion
California sea lion
is protected on the federal Marine Mammal
Protection Act (MMPA), passed in 1972, which outlaws hunting, killing, capture, and harassment of the animal. In 1994 an amendment to the Act allowed for the possibility of limited lethal removal of pinnipeds preying on endangered salmonids should the level of predation be documented to have a significant adverse impact on the decline or recovery of ESA-listed salmonids.[44] Applications have been granted for removal of several individual sea lions at Ballard Locks[45] and at the Bonneville Dam, where up to 92 sea lions can be killed each year for a 5-year period.[46] Critics have objected to the killing of the sea lions, pointing out that the level of mortality permitted as a result of recreational and commercial fisheries in the river and as part of the operation of hydroelectric dams pose a greater threat to the salmon.[47] These animals exploit more man-made environments like docks for haul-out sites. Many docks are not designed to withstand the weight of several resting sea lions which cause major tilting and other problems. Wildlife managers have used various methods to control the animals and some city officials have redesigned docks so they can better withstand them.[48][49]

2015 Californian shore sea lions pups crisis[edit] In January and February 2015, 1450 malnourished or sick sea lion pups were found along stretches of the California coast, and estimations give a higher number of dead pups. The National Oceanic and Atmospheric Administration has pointed to unprecedentedly warm Pacific coastal waters, related to Pacific decadal oscillation
Pacific decadal oscillation
and El Niño, as the likely cause. Elevated water temperatures reduced the abundance of anchovies, sardines and mackerel, principal components of the sea lion pup diet during nursery season.[50] This caused many sea lion pups to starve, while others died when they took to open waters in search of food at too early an age [51]. Several months earlier, in the Summer of 2014, a large number of Cassin's auklet chicks died during the fledging period due to similar circumstances brought about by elevated water temperatures.[52]

and Washington state governments annual killings[edit] In November 2018, the State of Oregon
obtained a permit to kill 93 sea lions per year below Willamette Falls. Under a similar program, Oregon
and Washington had killed over 150 sea lions on the Columbia river by January 2019.[53][54]
