9 The humpback whale

CONNOR'S MISSION NOTES. THE HUMPBACK WHALE. * Latin name: Megaptera novaeangliae. * Animal type: Mammals一they breathe air, have warm blood, and give birth to live young. * Location: Worldwide, but usually nearer coasts. * Length: Up to 56 ft (17 m). * Weight: 37 tons (34 metric tons)一heavier than five African elephants! In the southern oceans, humpback feed mainly on Antarctic krill. Each whale has a unique pattern on the underside of its tail. The pectora! flippers of the humpback are one-third of its body length一longer than those of other whales.

康纳的任务记录。座头鲸。 *拉丁名：Megaptera novaeangliae。 *动物类型：哺乳动物——它们呼吸空气，有温血，并能生下活的幼崽。 地点：世界各地，但通常靠近海岸。 *长度：高达56英尺（17米）。 *重量：37吨（34公吨）——比五头非洲大象还重！在南大洋，座头鲸主要以南极磷虾为食。 每条鲸鱼的尾巴底部都有独特的图案。 pectora !座头鲸的鳍是其体长的三分之一，比其他鲸鱼的鳍长。

Barnacles live on the whale's snout. The humpback has a pair of huge nostrils on the top of its head. These are called blowholes, and they close when the whales dive underwater. BEHAVIOR. * Every year, most humpbacks migrate to warm waters to give birth to their young. They swim thousands of miles. * Humpbacks live in groups called "pods," which include up to 15 whales. * An adult humpback can hold its breath underwater for 45 minutes—but usually stays under for 10–15 minutes before coming up for air. WHAT A TUNE! Male humpbacks make sounds known as whale songs. These calls can be heard by whales many miles away and last for up to 30 minutes. Scientists think they might be a way to attract females, to protect their territory, or to communicate with each other.

藤壶生活在鲸鱼的鼻子上。 座头鲸的头顶上有一对巨大的鼻孔。 这些被称为喷水孔，当鲸鱼潜入水下时，它们会关闭。 的行为。*每年，大多数座头鲸都会迁徙到温暖的水域生育后代。 他们游了几千英里。 座头鲸生活在被称为“豆荚”的群体中，其中包括多达15头鲸鱼。 *成年座头鲸可以在水下憋气45分钟，但通常会在水下待10-15分钟才会浮出水面换气。 多么美妙的曲调！雄性座头鲸发出的声音被称为鲸鱼之歌。 这些叫声可以被几英里外的鲸鱼听到，持续时间长达30分钟。 科学家们认为，它们可能是一种吸引雌性、保护领地或相互交流的方式。
