  The only animals that can truly fly are birds,insects,and one type of mammal, which is of course the bat. Other animalsmanage to travel through the air by gliding from great heights, or leaping from the depths。

  真正可以飞的动物只有鸟类、昆虫还有一种哺乳动物——当然那就是蝙蝠。其他有些动物可以靠从高处向下滑翔或者从低处向上跳跃来在空中“飞行”。

  1.Flying Mobulas The mobula or devil ray is related to manta rays. They can grow up to 17 feet wide and tenfeet long. These muscular fish can leap several feet out of the water, but no one is quite sure why they do it。

  1. 飞行蝠鲼

  蝠鲼,也被称为“鬼鳐”,属于蝠鲼科。它们可以长到17 英尺宽( 约为5.18 米)10 英尺长( 约为3米)。这些飞行蝠鲼可以跃出水面几英尺高,但没有人很确定它们为何这样做。

  2. Flying Lemurs Flying lemurs of the family Cynocephalidaeare neither true lemurs, nor do they actually fly. They are also known by their Malaysian name, colugos. These mammals live in southeast Asia and are about the size of a house cat. Colugos glidebetween trees using their patagium, or flaps of skin between their front and hind legs and extending to the tail and the neck. Colugosare even webbed between their toes. The flying lemur is not alemur, but the four species of Cynocephalidae are the closes trelated family to primates。

  2. 鼯猴

  属于鼯猴科的鼯猴既不属美狐猴属,也不能真正飞行。它还以其马来语名字Colugo被人所知。这些哺乳动物生活在东南亚地区,体型与家猫差不多。鼯猴利用它们的翼膜在树之间滑翔,该翼膜是它们前后肢之间并一直延伸到尾部和颈部的片状悬垂物。鼯猴的趾间甚至都有膜。鼯猴并不是狐猴,但鼯猴科的四个物种是灵长类动物最近的亲戚。

  3. Flying Fish There are about 50 different species of flying fish,although they don’t fly so much as they leap from the water with a push of their powerful pectoral fins. Most of the species live in tropical waters. Fish have been observed skipping over the waves for as long as 45 seconds at a time. Why do they leap into the air? Possibly because air offers less resistance than water,and the fish can move faster. At least until they need to breathe。

  3. 飞鱼

  世界上共有大约50种不同种类的飞鱼,但它们其实并不是真正飞行,而是猛地推挤胸鳍跃出水面。多数种类的飞鱼生活在热带水域,它们曾被观察到在水面上一次性滑翔45秒钟。为什么它们跳向空中?可能是因为空中比水中阻力小,因此它们可以移动得更快——至少可以滑翔至它们需要再次呼吸为止。
