It is the exoskeleton that protects the ant on the outside and the internal structures. An ant’s body is divided into three main parts: a head section, a chest section and a tummy section.
Body Structure of an Ant
The ant is very soft on the inside. So the exoskeleton of an ant is like armour that protects all the mushy soft internal body parts. The exoskeleton is made up of chitin which is a very strong substance. Some parts of the exoskeleton extend to the inside of the body so that the tiny muscles can attach to the body parts inside. Like the ant’s head is attached to the chest part with the help of the exoskeleton. This is known as the tentorium and it somewhat functions like a bone.
Ants are also formed from larvae but once they grow up and become adult ants they do not change their forms. The body structure is formed mostly by the skin rather than by the bones.
