A
Pierre is a 25-year-old penguin(企鹅)at the California Academy of Sciences. Due to his old age, he was losing his feathers, which made him feel too cold to swim in the pool. Therefore, biologists at the academy had a wet suit created for this penguin to help him get back in the swimming pool.
Unlike marine(海生的)mammals, which have a layer of blubber(鲸脂)to keep them warm, penguins depend on their waterproof feathers. Without them, Pierre was unwilling to jump into the swimming pool and ended up trembling on the side of the pool while his 19 peers played in the water.
