Cockroach Locomotion and Adaptations

Cockroaches can mimic humans by running on two legs, which is not just for show. This method of locomotion is faster, easier on their brains, and more energy-efficient. Not all cockroach legs are equal; some are shorter and create drag, making them less useful at high speeds. To avoid overloading their nervous system, cockroaches reduce their leg use to one pair, specifically the rear legs, which are the most energy-efficient.

Why do cockroaches run on two legs?

• To improve their vision

• To confuse predators

• To conserve energy

• To mimic human movement

What is one benefit of cockroaches running on two legs?

• It is faster

• It increases their weight

• It makes them more visible

• It helps them climb

How does running on two legs affect a cockroach's nervous system?

• It has no effect

• It makes them smarter

• It overloads it

• It simplifies control

Why do cockroaches use only their rear legs when running fast?

• To look bigger

• To jump higher

• To scare predators

• To reduce drag

What is a characteristic of cockroach legs that affects their movement?

• All legs are the same length

• Some legs are invisible

• All legs are equally strong

• Some legs are shorter
