How Many Babies Can a Sea Lion Have at One Time Where Sea Lions Sleep

ABOUT CALIFORNIA SEA LIONS
Concrete DESCRIPTION
Males tin reach a size upwardly to 8 feet long and 700-one,000 lbs.
Females are smaller, reaching 6.5 ft long and upward to 240 lbs.

Adult males abound a large bump of bone on the top of their heads, known as a sagittal crest, as they reach sexual maturity. Females practise not showroom this, having lower and smaller foreheads. Different harbor seals and other true seals, California body of water lions accept external ear flaps and long, domestic dog-like muzzles.

Males are a chocolate chocolate-brown, females are tan to golden brownish.The coat darkens to well-nigh blackness when wet. As adult males historic period, their heads become light tan. Developed females are a lighter gold color. Ocean lions molt (shed their pilus) every year later on breeding season.

Sea lions have sleek torpedo-similar bodies and are powerful swimmers.

LIFESPAN 20-thirty years

LOCOMOTION

Graceful and acrobatic in the water, body of water lions propel themselves through the water with large, wing-like fore flippers, usimg their hind flippers and tail for steering. Able to rotate their hind flippers for locomotion on land, sea lions are quite are nimble and can gallop onshore. They have a short tail.

They have no claws on their fore flippers. but use their nails on the back flippers for grooming their coats.

RANGE AND HABITAT The California sea lion resides along the Pacific Coast mainly in the waters of central Mexico and California where they brood, but in non-breeding flavor can exist institute as far north as Vancouver Island, Canada. These highly intelligent and social mammals breed in large colonies on offshore isle rookeries such as California'due south Channel Islands.

In one case the convenance season is over, they will often gather at marinas and wharves.

Information technology is common to see California ocean lions within Puget Sound and Seattle's Elliott Bay during fall months when salmon take returned to spawn.

DIET AND HUNTING California ocean lions feed on more than 50 species of seafood, mainly squid and fish. Even though they have fearsome canine teeth (used primarily to grab fish), body of water lions typically swallow their food whole.

MATING AND Breeding California sea lions breed around May to June. Males and females attain sexual maturity betwixt four-five years of historic period.

Establishing a territory is important to a male's success in breeding and mating begins approximately iii weeks later on the females give birth. Postural displays, fighting (often violent) and barking and growling is mutual during the mating season as males (known as bulls) compete for females (cows). Males gather a number of females and young into a group called a harem and protect them throughout the breeding flavour. Mating and birthing takes place in remote rookery locations, prophylactic from humans and predators.

PUPPING The females accept gestation menstruum of 11 months and give birth from June to Baronial. Mothers may give birth to a single pup on land or in water. Pups and moms learn to recognize each other's distinct vocalizations and smell, playing a vital part in the survival of the pup.

Pups nurse for six months to a year even though they tin can digest nutrient at 3 months of historic period. Pups learn to swim and chase at about two months and play together onshore. They leave their female parent after a twelvemonth.

Behavior Later the convenance flavour, female California sea lions normally stay in southern waters while the developed males and juveniles generally migrate due north to feeding sites for the winter. Males utilize raucous vocalization (loud barking, grunts and growls) and posturing movement as they battle for dominance and territory. Non-breeding groups are gregarious and haul out together in groups called colonies.

Winter haul-outs are often in more than exposed locations. Most sea lions found on human-made structures such equally piers, platforms and docks are males or juveniles. Ocean lions are frequently seen on navigational buoys, resting and warming up.

Sailing is a behavior sea lions use to warm upward or absurd downwards in the water past resting with only flippers and nose visible above the water. This is chosen thermoregulation. When a number of bounding main lions cluster together to rest or sleep, it is known as rafting. Typically this will occur in areas where there is no suitable haul-out. The Marine Mammal Stranding Network receives many calls from by concerned onlookers about "entangled" sea lions, when truly the animals are just warming up.

California ocean lions can dive upwardly to 600 feet and stay submerged for 40 minutes. Their ears and nostrils close when diving under water.

The fastest swimmers of all pinnipeds, they can reach speeds of upwards to 30 mph. They frequently bound out of the water in a behavior called porpoising.
