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 ...
The average lifespan of a northern elephant seal is 9 years, while the average lifespan of a southern elephant seal is 21 years. [26] Males reach maturity at five to six years, but generally do not achieve alpha status until the age of eight, with the prime breeding years being between ages 9 and 12. The longest life expectancy of a male ...
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.
Elephant seals can reach over 13 feet in length and can weigh 4,400 pounds, or 2.2 tons, according to the National Oceanic and Atmospheric Administration. They typically live about 19 years.
Cal Poly researchers tag 10 seal pups to examine migration habits. Elephant seals are migratory, with the adults swimming north along the coastline as far as Alaska and out into the northern ...
Elephant seals are at sea for most of the year and there are vast distances between their breeding and molting sites. The northern elephant seal is one of farthest mammalian migraters, traveling 18,000–21,000 km (11,000–13,000 mi). Otariids tend to migrate less than phocids, especially tropical species. [91]
Tracking data showed Monarch traveled well beyond what anyone thought a pup could do during its first migration.
Elephant Seals tend to live in the eastern and central North Pacific Ocean. They can live as far north as Alaska. But Elephants don't stay in the same place their whole lives. These seals can move ...
