Animal Life Cycles

I read “Animal Life Cycles” this week. There are a lot of animals in the world so this book writes various life cycles of them for example insects, fish, amphibians, reptiles, birds and mammals. This book has a lot of information so if you read this, your knowledge will increase. 

Especially, I’m going to write one thing of them. It is insects. Many people know that insects change in amazing ways during their life. Almost all insects start their life in an egg. The young insect grows inside the egg and then it hatches. And they have a hard cover, called an exoskeleton. When the exoskeleton is too small for the young insect, it breaks open and comes off. A new exoskeleton grows under the old one. This is called molting which we know. Then, some insects grow wings that get bigger every time they molt. After the insect molts for the last time, it becomes an adult that can fly and produce young. This is called incomplete. Insects change their shapes one after another. I think it is interesting to change shapes and grow up quickly to produce young. 

I could get a lot of knowledge from this book!
