The Journey of Humpback Whales

The journey of humpback whales.

座头鲸的迁徙之旅。

Humpback whales are mammals, not fish. This means they can't breathe underwater. Humpbacks have two big nostrils, blowholes, on the top of their heads, and must come to the surface to breathe.

座头鲸是哺乳动物，不是鱼类。 这就意味着它们没办法在水下呼吸。 座头鲸的头顶长着两个大大的鼻孔，也就是喷水孔， 必须浮到海面上来呼吸。

Adult humpbacks can stay underwater for up to 45 minutes and dive to a depth of 180 meters.

成年座头鲸最多可以在水下停留45分钟，下潜深度可达180米。

They're called humpbacks because they arch their backs when they dive.

它们之所以叫座头鲸，是因为下潜时会弓起背部。

Humpbacks are known as acrobats of the sea because they leap out of the water. This is called breaching. Humpbacks breach to impress other whales and remove little creatures like barnacles and sea lice from their bodies.

座头鲸被称为海洋杂技演员，因为它们会跃出水面。 这种行为叫做跃身击浪。 座头鲸跃身击浪是为了吸引其他鲸鱼的注意，同时甩掉附着在身上的小生物，比如藤壶和 海虱。

Fact. Each humpback has different white, grey and black patterns under its tail.

小知识。 每头座头鲸尾巴下方的白、灰、黑色花纹都各不相同。
