Monachus monachus
Mediterranean monk seal

Monachus monachus, also known as the Mediterranean Monk Seal, is found around the Mediterranean Sea region and the Northwest African Coast. There are populations that are located in Mauritania/Western Sahara, Greece, and Turkey. Small numbers have also been seen in Morocco, Algeria, Libya, the Portuguese Desertas Islands, Croatia, and Cyprus.

Mediterranean monk seals are usually found along coastal waters, especially on the coastlines of islands. They are sometimes found in caves with submarine entrances when the female is giving birth and just to get away from other disturbances, such as boats.

Adult Mediterranean monk seals can be any color from dark brown or black to light grey. They are usually light gray along the belly. Pups have a black woolly coat and a white or yellow patch on the belly. They molt at about 4-6 weeks and their black woolly coat is replaced by a silvery gray coat that can darken over time.

Adult males are on average about 2.4m in length and females are slightly shorter. Males weigh about 315 kg and females weigh about 300 kg.

These seals live up to 30 years of age.

The Mediterranean monk seal spends most of its time in a limited range; they don't migrate long distances. There can be up to 20 individuals in a colony of Mediterranean monk seals. On land, the seal is a solitary species.

In the water, they are very good divers and swimmers. They swim so well that they can outmaneuver a shark.

When communicating with each other they make very high pitched sounds. This is done mainly while in the water to let each other know if something is wrong or if danger is approaching.

Mediterranean monk seals are diurnal. They feed in shallow coastal waters on a large variety of fish. This includes eels, sardines, tuna, lobsters, flatfish, and mullets. They also feed on cephalopods such as octopuses.

The only way that Mediterranean monk seals affect humans negatively is that compete with fishermen. These seals are mainly harmless otherwise.

In the past the Mediterranean monk seal was killed for its skin and body parts, which were said to provide protection against a variety of medical problems. The seal has also been killed for food.

Fewer than 500 individuals of Mediterranean monk seals remain in the world today. They have been killed by fisherman who see them as competition, and many have been lost due to being caught in fishermans' nets. Pollution and boat traffic are also a problem for this species. Pollution comes mainly from human waste. This waste gets into the water in which the seals live and into the food that they eat. The problem with boat traffic is from a lot of boats being in the same area that the seals occupy, resulting at worst in collisions between seals and boats

This seal is one of the world's rarest mammals, and it is on the list of the 20 most endangered species.

Another issue with the seal is that it is very sensitive to disturbances. Pregnant females are especially sensitive and will often abort when disturbed.
