Is a seal a sea lion?
Seals and sea lions are marine mammals called 'pinnipeds' that differ in physical characteristics and adaptations. Sea lions (left) are brown, bark loudly, "walk" on land using their large flippers and have visible ear flaps. Seals have small flippers, wriggle on their bellies on land, and lack visible ear flaps.

How many toes does a seal have?
Like land mammals, seals have five bony digits in the hind, or pelvic, limbs. The first and fifth digits are long and stout; the middle digits are shorter and thinner. Digits of the hind flippers are webbed. When a harbor seal spreads its hind flippers, the flippers look like wide fans.

Why are seals eyes black?
Their eyes are specially adapted for sight in dark and murky water.

When a seal is out of the water, mucous surrounding the eyes gives them a wet, 'tear-rimmed' look.
What are female seals called?
A large group of seals during breeding is called a harem. Adult males are called bulls and females are called cows, while a young seal is a pup.
Why are seals fat?
Seals have a thick layer of fat called blubber that helps them to trap warmth in their bodies. Without this blubber they would not be able to stay warm in cold waters. The blubber acts as a form of insulation to keep their internal body temperatures warm.
Do seals lay eggs?
Seals are mammals. This means that their reproduction works like most mammals. It means that the sperm has to fertilize the egg inside the female. ... Seals mate on land about 6 weeks after seal pups are born.
