Hooded Seal

Cystophora cristata

Vulnerable

At high risk of extinction in the wild over the medium term.

Spotted something wrong?

The hooded seal is a large seal of the North Atlantic that spends most of the year on the open sea, diving to great depth in search of fish and squid. It gathers on drifting ice to give birth and mate in an extremely brief period. The males have two spectacular nasal ornaments that they use in courtship displays and in confrontations. Commercial hunting and, above all, the retreat of the seasonal ice it depends on for breeding have caused its decline.

Fun facts

  • GeneralThe male inflates a red sac out of one nostril like a balloon during courtship.
  • comportamientoThe males can inflate a red nasal membrane into a balloon as part of their dominance and courtship displays.
  • It has the shortest lactation of any mammal: barely four days, during which the pup doubles its weight on milk that is more than 60% fat, after which the mother leaves it on the ice.
  • The male inflates a black nasal sac that covers his forehead like a hood and can also push his nasal septum out through one nostril and blow it up like a red balloon, two separate ornaments that he displays to rivals and females.

It's documented in 6 protected areas — one reason why protecting these places matters for its conservation.
