A
Elephants are huge and amazing animals, and their tails are quite special. They use their tails to show their feelings. When they're happy, their tails wag back and forth(来回摇摆) like a dog's tail. The hairs on their tails are very thick(浓密的) and can be as long as 1 metre. Elephants also use their long tail hairs to keep away flies.
Owls have very strange and interesting eyes. The shapes(形状) of their eyes are like tubes(管子), not like our round eyes. Because of this, owls can't move their eyes. To see different things, they have to turn their heads. Owls can turn their heads almost all the way around.
The anglerfish(琵琶鱼) has a special "light" on its head that helps it catch food. In the dark, deep sea, small fish see the light and think it's something to eat. When they swim close, the anglerfish quickly opens its big mouth and eats them. The anglerfish is like a smart fisherman. It can catch food without(没有) moving much.
