How Many Different Kinds of Animals Live on Earth?
The story of Noah’s ark tells us that to save the earth he took a pair of every kind of animal on his ark and saved the earth from total destruction. But if this could really have happened, then the ark must have been too big indeed! Because the number of different species or kinds of animals that live on earth is much more than most of us imagine.
There are about 5,000 species of mammals. The number of kinds of birds are over 15,000. There are more than 3,000 kinds of snakes. The sea animals and the mollusk family has a variety of more than 100,000 members. The protozoas or the one-cell living creatures are of about 15,000 kinds.
And the insect family has an unbelievable variety of 750,000 different kinds! All this makes us realise that there are at least three million different kinds of living beings on earth!
