Grey Seal Facts

Grey Seals are one of the rarest species of seals on Earth. They are spread out in North East Atlantic, with large numbers of them on the waters of Britain. When born, the pups are white in color, and when grown the bulls are usually darker than the cows. They like to live in open sea, with rocky islands and coasts. They like to find and eat fish, crustaceans, and mollusks.

The grey seal is Britains largest carnivorous mammal. The thick layer of blubber and waterproof fur allows it to survive in cold water temperatures that are so cold that if would kill a human in minutes. When at sea, the grey seal only hunts alone. It’s large eyes let it see well in the dark, murky waters of Britain. The grey seal also uses highly sensitive ears when searching for prey. It is hard to see a grey seals ears because it has no external ear flaps. It is capable of plugging his ears while diving in and out to keep the water out as to not get an ear infection.

The seals whiskers can also detect prey, if a vibration is felt. The grey seal is able to stay underwater for up to 16 minutes, even though they usually only stay under for about 5. It is able to stay underwater that long because it’s heart is able to slow down during a long dive to keep in the lack of oxygen. Female grey seals give birth to a single pup on-shore. At birth, the pup is covered in a thick white coat, but is fully covered in an adult coat by 3 weeks of age. The pup is also fully grown around the same 3-4 weeks because of it’s mothers milk.

The mother abandons the pup when fully grown so she is able to mate again. After mating, the female returns to sea, but the egg doesn’t start developing until about the same time a year later. Humans have been hunting the grey seal for years because of it’s coat and meat. Later on, grey seals were being stolen around British shores, because fishermen said that they did a lot of damage to fish stocks and nets. The grey seal is now protected by the law. Fishermen still blame the grey seal for reducing the population of salmon and cod in the North Sea, but scientists say that it is caused by many years of overfishing.
