penguin

Emperor penguins are known for huddling together in large groups to stay warm during the Antarctic winter.

(Chinese) 帝企鹅以在南极冬季成群结队挤在一起取暖而闻名。

Unlike most birds, a penguin uses its wings as flippers to propel itself through the water at high speeds.

(Chinese) 与大多数鸟类不同，企鹅将翅膀当作鳍肢，在水中高速推动自己前进。
