【智慧训练】
The Harp Seal is one of nature’s most beautiful and lovely creatures(动物). Many years ago it was hunted for its white fur. Catching or killing Harp Seal is now against law.
The Seals spend the summer months moving in large groups. Harp Seals close their noses and ear holes when swimming deep in water, but they have to come out of the water for air from time to time. Their favourite place to rest is on the top of icebergs(冰山).
The mother Harp Seal gives babies in February or March and feeds her children for 14—18 days. Baby Harp Seals begin to lose their white fur at around six to eight weeks of age. When they grow up, the Harp Seals have brown skin. At birth, Harp Seals weigh 12kg but can weigh up to 130kg as they become grown-ups. Harp Seals eat small fish, shrimps(虾) and krill(磷虾). However they are living in different places. Father Harp Seals can live as long as 29 years while mother Harp Seals usually live for longer than 30 years.
Since the Canadian Government passed laws to keep the baby seals from hunters, their numbers have gone up to more than one million. Now every year, thousands of visitors crowd to the pack ice(大片浮冰上) to witness the wonderful picture of newly-born Harp Seals.
