The Mediterranean Monk Seal is one of the most endangered mammals in the world. There are only 350 to 450 of these seals left. It is one of the 3 species of monk seals known. The other 2 are the Hawaiian Monk Seal and the Caribbean Monk Seal, which is now extinct since 1952. Both the Mediterranean Monk Seal and Hawaiian Monk Seal are now endangered species. Because people suck it so much a threat to this seal, the Mediterranean Monk Seal no longer gives birth on open beaches. Instead, they now give birth in sea caves that are inaccessible to people.
