The number of legs on the thorax of a cockroach is a commonly asked question, and to answer it accurately, let’s analyze the structure of the cockroach’s body in detail.
Cockroaches have bodies that are divided into three main parts:
- Head
- Thorax
- Abdomen
Explanation in Simple Words
The head contains the brain, mouthparts, and a pair of long antennae that help the cockroach sense smells and vibrations. Their eyes are made of many tiny lenses, called compound eyes, but they can’t see very well.
The thorax is the middle part of the body and is where all the legs and wings are attached. Cockroaches have three pairs of legs, which means six legs in total. These legs are jointed and help them move quickly and even climb walls or ceilings. Some cockroaches also have two pairs of wings, but not all of them can fly.
The abdomen is the last part. It contains parts for reproduction and also has small structures called cerci at the back. These cerci sense movements and help the cockroach react quickly to danger, sometimes even before the brain knows what’s happening!
So, since all six legs are attached to the thorax, the correct answer is 6 legs.
Fun Fact: There are over 4,600 species of cockroaches, but only around 30 live near humans, and just a few are known as common pests.
