Do you know how many kinds of earthworms there are?There are about 1800 kinds in the world!They can be brown,purple,red,blue,green.They can be as small as 3 cm long and as large as 3 m long.The garden earthworms we have in Canada are 10 cm to 20 cm long and are a pink brown color.
The best time to see earthworms is at night,especially a cool,damp night.That’s when they come up from their burrows(地洞)to hunt for food.Earthworms don’t like to be in the sun.That’s because they breathe through their skin,and they can’t breathe if their skin gets too dry.So they try to stay down in the earth while the sun is out.You may have noticed that if you happen to dig up an earthworm,it soon burrows back into the earth.Sometimes earthworms don\'t make them back into the earth.When that happens,you\'ll see a dead worm all dried up by the sun.Earthworms must come out of the earth if it rains a lot,because they can\'t breathe in their flooded burrows.What a dangerous life!
你知道世界上有多少种蚯蚓吗?有大约1800种!它们可能是棕色,紫色,红色,蓝色或是绿色.它们中小的只有3厘米而长的能达到3米.加拿大的花园蚯蚓(应该是蚯蚓的一种)就是一种身长在10到20厘米之间的粉棕色蚯蚓.
观察蚯蚓最好的时间是在空气潮湿而又凉爽的晚上,它们在那时会从洞里出来觅食.由于蚯蚓是靠皮肤呼吸,所以它们讨厌阳光.因为太阳会使皮肤变干,所以在有太阳的时候它们都会尽量躲在地下,当它们没有返回地下的时候,你就会看到一个被太阳烤干的死蚯蚓.而蚯蚓在大雨天一定会钻出来,因为充满水的地洞同样令它们无法呼吸,多么艰难的生活!
