Why are American roaches so big?
Many insects grow larger when the air around them is more oxygen-rich. That’s because bugs breathe through their skin, using a series of tubes called tracheal tubes. When oxygen levels rise, the tubes can be narrow, but still deliver enough oxygen to power big bugs.
Who created cockroaches?
The cockroach, having been present on the planet amongst the first insects, currently has no proven origin. Scientist know that most roaches have come from the tropical regions all over the world and adapted to colder conditions ” having over 300milion years to do so.
