Weddell Seal

Leptonychotes weddellii

Least Concern

The species is abundant and widely distributed; it faces no significant short-term risk.

Spotted something wrong?

The Weddell seal is a pinniped mammal of the family Phocidae. It was named in honour of Sir James Weddell, commander of the British marine expedition to the Weddell Sea. They live in small groups and inhabit the circumpolar region of the southern hemisphere, Antarctica. Older estimates put the population at around 800,000, although more recent ones are much lower. They are seen regularly on the many ice-free islands of the Antarctic Peninsula. It is not a migratory species, and its local movements are the result of changes in ice conditions.

Fun facts

  • comportamientoIt gives birth on Antarctic fast ice and can stay under the frozen surface, finding its breathing holes from a remembered map of the area.
  • It gnaws the ice with its incisors and canines to keep its breathing holes open all winter, work that wears down its teeth and ends up limiting its life expectancy.
  • It is the southernmost-living mammal in the world: there are colonies breeding less than 1,300 kilometres from the geographic South Pole.
