B The Harp Seal is one of nature’s most

问题：

B

The Harp Seal is one of nature’s most beautiful and appealing (吸引人的) creatures. Many years ago it was hunted for its fur. Hunting Harp Seals is now illegal.

The seals spend the summer months migrating (迁徙) in large groups. Harp Seals close their nostrils (鼻孔) and earholes when diving in water, but have to surface frequently to breathe. Their favourite place to rest is on the top of icebergs.

The female Harp Seal gives birth in February or March and feeds her pups for 14-18 days. Baby Harp Seals begin to lose their white fur at around six to eight weeks of age. As an adult, the Harp Seal has brown skin. At birth, Harp Seals weigh 12kg but can weigh up to 130kg as adults. Harp Seals eat small fish, shrimps and krill. However, they are able to switch from one food to another depending on what they can get as food. Males have a lifespan of 29 years while females usually live for longer than 30 years.

Since the Canadian Government introduced laws to protect the seal pups from hunters, their numbers have increased to more than one million. Now every year, thousands of tourists flock to the pack ice to witness the wonderful sight of new pups born in spring.
