The cockroach is a common insect. Cockroaches are easily recognizable by people. They are usually black or brown-banded, half to two inches (minus their long antennae) long insect. Male species of cockroaches have wings whereas females don’t.
Most cockroaches have vestigial wings (small undeveloped wings) that don’t allow them to fly.
Cockroaches are very similar to other insects in terms of their bodies. Their body is divided into three parts named as “Head”, “Thorax”, and “Abdomen”. Three pairs of joint legs, pair of antennae, and exoskeleton.
Roaches tend to shed their exoskeleton or molt several times in their lifetime. Roaches get white bodies after molting (which is a very week) until they developed a hormone called “Bursicon".
Bursicon is also the reason behind their hardened brown and black exoskeleton.
Roaches have a brain in the head part as any other insect. However, roaches' nerve system activity occurs in a nerve called Ganglia that is located in their bodies. That is also the reason, they can live more than a week even after without ahead.
The other reason is that they don’t need a nose or mouth to breathe. Roaches breathe through the holes present in their sides also known as spiracles. Roaches die in lack of water or are not able to drink water.
