Scientists have actually performed brain surgery on cockroaches. German cockroaches can survive for up to one month without food and two weeks without water. A cockroach can change directions up to 25 times in a second. If a cockroach breaks a leg it can grow another one. The earliest fossil cockroach is about 280 million years old – 80 million years older than the first dinosaurs! Cockroach can live up to nine days without its head. |
