How often do Australian sea lions breed?
Australian sea lions have a breeding cycle of approximately 17.6 months. These non-annual cycles are affected by some unknown factor, not by environmental influence as previously thought (Higgins, 1993). Some females do not produce young in consecutive breeding seasons (Nowak, 1999).
How long do baby sea lions stay with their mothers?
Sea lion pups are completely dependent on their moms for the first 6 months and are not usually completely weaned until almost a year old.
How long are Australian seals pregnant for?
Summer is the optimal time for a pup to survive: their food (mostly fish and shellfish) is abundant and the sea is wam. The active gestation (pregnancy) of an Australian Fur Seal is 8-9 months.
Do Australian sea lions migrate?
There is no evidence of migration or seasonal movements, apart from some movement of adult and subadult males on the west coast of Western Australia, and it appears that Australian sea lions tend to stay around their haulouts and breeding sites. Females may move with their pup to other haulout areas to nurse them.
How many pups do Australian sea lions have?
Timing of the birth of pups is not the same at each site. Young can be born anytime from January to June after a gestation period of about 12 months. Despite the fact that females give birth to only one young and may not breed again for two to three years, pup mortality is high in the first six months after birth.
What happens to a sea lion pup if the mother dies?
During the mother's absence, the pup doesn't eat. Females continue a pattern of going to sea for several days and nursing ashore for several days until they wean their pups. This takes almost a year. If you see a pup on the shore, please leave it be.
Can a seal and sea lion mate?
Unlike whales, seals and sea lions have not developed the ability to mate and give birth in the sea. Sea lions and fur seals bear their young on land.
Do sea lions jump out of the water?
They are sometimes seen porpoising, or jumping out of the water, presumably to speed up their swimming. Sea lions have also been seen surfing breaking waves.
How far out to sea do seals go?
Adult harbor seals can dive as deep as 1500 feet and stay underwater over 30 minutes!
How many pups do seals have?
Females generally give birth to one pup each year.
How long do seals carry their pups?
Mothers nurse their pups for approximately 16 days. After pups are weaned, mothers may leave the colony but pups remain for several more days or weeks living off blubber reserves.
What eats an Australian sea lion?
Predators. Adult Australian sea lions are eaten by Great white sharks and are occasionally killed by other animals such as stingrays. Pups are vulnerable to attack by other smaller shark species.
Why do Australian fur seals have whiskers?
They have a pointed face, whiskers that help them find food and very sharp teeth similar to a bear. Their flippers are forward facing, allowing them to walk on land. While they appear to mainly shuffle along, Australian Fur Seals can move very quickly if they feel threatened.
How many sea lions are killed each year?
About 900 California sea lions and 250 Steller sea lions could be killed each year, starting about 110 miles (180 kilometers) from the river's mouth and extending 300 miles (480 kilometers) upstream.
