Question

Are elephant seals in danger of becoming extinct today? Why or why not? Please answer detaildly

Answer 1

Answer:

Elephant Seals are not endangered. They are actually doing very well. According to the IUCN Red List, both species are considered to be Least Concern. The Southern Elephant Seal population is stable, the number of Northern Elephant Seals is even increasing.

Explanation:

The Southern Elephant Seal always has been safe, but there was a point in history that the Northern Elephant Seal was very close to extinction. In the 19th century, sealers regularly raided elephant seal rookeries for their blubber, which was used to make oil. Elephant seals are huge, but clumsy at land and make an easy prey, especially since they live in large colonies, which make them easy to find. By the 1890s, only one colony of 100 animals (some say it was even as low as 20 animals) was known on an island off the coast of Mexico.

But they recovered. In 2010, the population was estimated to be between 210,000 and 239,000 animals. They have recolonized offshore islands off the coast of California and Baja California, even started rookeries on the mainland. Pups have been born as far north as British Columbia.

Least Concern doesn’t mean completely free of risk. The population wen through what is called a ‘genetic bottleneck’. When the world population dropped to 20–100 individuals, the Northern Elephant Seal lost a lot of its genetic diversity. All the current animals are descendents of that very small group that survived the 19th century. That means that all living Northern Elephant Seals are closely related to each other, which makes the species very vulnerable to disease outbreaks. But as of yet, the species is considered to be safe.

Answer 2

Answer:

The northern elephant seal is the largest of the “true” seal in the Northern Hemisphere. Adult males use their large, inflatable noses during the winter breeding season to resonate sound when vocally threatening each other. The largest colonies of northern elephant seals are found off southern California in the Channel Islands. They have one of the longest migrations of any mammal; some have been recorded traveling over 13,000 miles roundtrip.

Northern elephant seals were once thought to be extinct due to commercial sealing in the 1800s. Populations of northern elephant seals in the U.S. and Mexico were all originally derived from a few hundred individuals surviving in Mexico. Its population began to steadily increase in the early 1900s.

Northern elephant seals, like all marine mammals, are protected by the Marine Mammal Protection Act.
