Animal Exoskeleton

Many insects, spiders ... have their skeleton on the outside, this is called EXOSKELETON

The exoskeleton is made of chitin and the bug is growing inside this box while going by becoming increasingly hard, until when you can not grow but the only option is to break and give way to a new individual bigger.

This is how they grow eg crickets, what we see in the photo is not more than skin, skin to skeleton for this insect.

Nature is very curious and through the power of observation and understanding that we humans have developed numerous inventions and one of them are exoskeleton suits that use the armed forces and the army of many countries, which give them more strength and endurance.
