4. They Will Eat Each Other

Cockroaches Eat

Cockroaches can survive a month without food, but if there are enough of them around, they won’t have to. Cockroaches are cannibalistic creatures that will eat each other. When cockroach populations get too large, that’s exactly what they do. This ensures they have something to eat and helps them with population control as well.

3. They Can Live Without a Head

Cockroach Head

Chop off a cockroach’s head and he can keep on living for a week. Cockroaches breathe through tiny holes in their bodies called spiracles, not through their mouths. Their breathing doesn’t rely on brain function, and neither does their circulatory system. The headless creature will continue to carry on until it dies of thirst or infection.

2. They Can Hold Their Breath for 40 Minutes

Cockroach Breathe

The amazing cockroach can hold its breath for as long as 40 minutes and can swim underwater for 30 minutes. The cockroach has no lungs but transfers oxygen through spiracles in its body to the cells via the trachea, or tubes. Like other insects, cockroaches hold their breath at rest in order to conserve water.

1. Most Can’t Fly

Cockroaches Can't Fly

While many species of cockroaches have wings, most of them cannot fly. Some species, including American cockroaches, can fly very short distances. Other species glide from higher areas to lower ones. The cockroach’s relatively large body and small wing mass don’t make for easy flight. Instead, their fast and powerful legs carry them where they need to go. The American cockroach can move up to 59 inches per second. At speeds like that, they don’t need to fly!
