Biology of the Monk Seal

Bookmark and Share

Monk seals reproduce slowly, sometimes only every other year, starting at the age of four. Adult females come ashore to give birth to one pup, then remain on the beach nursing and protecting the pup for up to six weeks. Living off stored fat, the female does not leave the pup even to feed herself during this period. The pup may stay with its mother for as long as three years after weaning.

Habitat: The Mediterranean monk seal is a coastal species. Most monk seals are found on two types of coasts: archipelagoes, especially those with small islands, often uninhabitable by man because of water shortage; and cliffbound mainland coastlines. The monk seal currently uses caves, especially ones with submarine entrances, for rest and reproduction.
