Read about the harp seal and the ringed seal.
This is a picture of a seal pup. It has a white fur that will later become darker around the head and on the back a horseshoe-shaped marking will appear.
An adult seal eats up to 3 kg a day; it eats cod and crustaceans.
The harp seal takes advantage of the resistance in air being less than in water and swims like a dolphin, making it the fastest of seals.
What is air resistance?
How would it affect the harp seal if the stock of polar cod was depleted?
How does the seal pup obtain its insulating layer of blubber?
The ringed seal is the smallest seal in Greenland and the one that has adapted best to the life in the Icefjord.
The ringed seal survives in spite of the thick ice by making breathing holes with its teeth and claws. Furthermore it has a thick layer of blubber, comprising up to 40% of its body weight.
The ringed seal mostly eats polar cod and weighs 50-100 kg.
How has the ringed seal adapted to life in the Icefjord, making it possible to survive all year?
What natural enemies does the ringed seal have?
If an adult ringed seal weighs 87 kg, how many kilo would its layer of blubber amount to?
