Mediterranean Monk Seal

Monachus monachus

Vulnerable

It faces a high risk of extinction in the wild over the medium term. See full glossary

The Mediterranean monk seal is one of the rarest pinnipeds in the world and the only true seal native to warm European waters. It once occupied the whole Mediterranean, the Black Sea and the North African Atlantic, including the Canaries and Madeira. Hunting, first for skin and blubber and later out of conflict with fisheries, cornered it in three areas: the Aegean and the Turkish coasts, Cabo Blanco between Mauritania and Western Sahara, and the Madeira archipelago. Today it pups in sea caves with submerged entrances, refuges it did not previously need.

Fun facts

  • conservaciónIt is one of the most threatened pinnipeds on the planet, and its Caribbean relative has been considered extinct since the mid-20th century.
  • conservaciónIt is one of the most threatened marine mammals on the planet, and unlike most seals it usually pups inside half-submerged sea caves in the Mediterranean rather than on open beaches.
  • It appears as early as Homer's Odyssey and gave its name to the islet of Lobos, off Fuerteventura, where it was hunted in the 15th century: in Spain it disappeared in the 20th century and since 2021 traces of its DNA have again been detected in the Balearics.
  • Breeding in caves with underwater entrances is not its natural behaviour: it once pupped on open beaches and only took refuge in caves because of human pressure.
