Without question, cockroaches are truly one of nature's most amazing and enduring creatures. How amazing? Read on.

Cockroaches are thought to have originated 0ver 280 million years ago (during Carboniferous era).

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

Cockroaches bleed white blood.

Cockroaches have 6 hairy legs. The tiny hairs found on each leg gives them their sense of touch.

Cockroaches can hold their breath for up to 40 minutes and spend about 75 percent of time just resting. There are an estimated 5,000 species of cockroaches worldwide.

Some female cockroaches mate once and are pregnant for rest of their lives.

You've no doubt heard legend of headless cockroach. Well, in this case, legend also happens to be fact. A cockroach can live a week without its head. The roach only dies because without a mouth, it can't drink water and dies of thirst.

Cockroaches can run up to three miles in an hour.
