COCKROACH

                       COCKROACH

A cockroach can live for a week without its head. Due to their open circulatory system, and the fact that they breathe through little holes in each of their body segments, they are not dependent on the mouth or head to breathe.

A cockroach can hold its breathe for 40 minutes, and can even survive being submerged under water for half an hour. They hold their breathe often to help regulate their loss of water.

 Cockroaches can run up to three miles in an hour, which means they can spread germs and bacteria throughout a home very quickly.

A one-day-old cockroach, which is about is size of a speck of dust, can run almost as fast as its parents.

The world’s largest cockroach (which lives in South America) is six inches long with a one-foot wingspan.

Cockroaches are believed to have originated more than 280 million years ago, in the Carboniferous era.

Because they are cold-blooded insects, cockroaches can live without food for almost a month, but will survive only one week without water.
