Hooded seals shed their lanugo fur in the womb and are born with a thin non lanugo fur coat, which is a less efficient thermoregulating fur coat compared to some to other seal species (e.g., leopard seals). [26]
Elephant seals or sea elephants are very large, oceangoing earless seals in the genus Mirounga.Both species, the northern elephant seal (M. angustirostris) and the southern elephant seal (M. leonina), were hunted to the brink of extinction for oil by the end of the 19th century, but their numbers have since recovered.
Phocids such as elephant seals, grey seals and hooded seals have a lactation period that lasts days or weeks, during which they fast and nurse their pups on land or ice. The milk of these species consists of up to 60% fat, allowing the young to grow quickly. Each day until they are weaned, northern elephant seal pups gain 4 kg (9 lb).
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 ...
Gray seals and harbor seals are the two seal species found in the Seacoast year-round, while in the winter months, the region is also visited by harp and hooded seals that arrive from Arctic ...
Family Phocidae (true or earless seals) consists of around 19 species of highly aquatic, barrel-shaped animals ranging from 45 kg (100 lb) and 1.2 m (4 ft) in length (the ringed seal), to 2,400 kg (5,300 lb) and 5 m (16 ft) (southern elephant seal). Phocids are found throughout the world's oceans.
The postweaning fast ranges from two weeks in the hooded seal to 9–12 weeks in the northern elephant seal. [19] The physiological and behavioral adaptations that allow phocid pups to endure these remarkable fasts, which are among the longest for any mammal, remain an area of active study and research.
There’s a reason the male elephant seals lounging on the sand look a bit ratty. Bull elephant seals take over SLO County beaches. How will they spend the rest of summer?
