Seal

Description Of Seal:

The common seal tends to be found in colder waters in many places around the world. Many species of seal inhabit waters in the northern hemisphere and are often found in coastal waters where there is an abundance of food and fewer number of predators.

Seals are highly carnivorous marine animals that primarily hunt fish, squid and crustaceans (like shrimp and crabs). The large leopard seal is known to have a more diverse diet that not only includes larger species of fish but also penguins and the occasional sea bird.

Surprisingly seals only spend around half of their time in water as the other half is spent on land. After a gestation period of between 11 months and a year baby seals (known as seal pups) are born on land. Seal pups develop very quickly and some baby seals are often able to swim within a few hours of birth. Seal pups are born during the spring and summer months when temperatures are warmer and there is plenty of food.

Generally seals live until they are about 20 years old.Some species of seal live for a shorter period of time, where other seal species can live until they are nearly 40. Due to the fact that seals are a targeted food source for many species of animal.Some seals in the wild will only live for a very short period of time.
