As you may have guesses the fastest runners in the insect world are cockroaches, which can move almost one foot per second - translating to a little over 3 mph or 50 body lengths per second. This would be equivalent to a human sprinter running the 100 yard dash in 1 second or approximately 200MPH!
The perentie monitor (Varanus giganteous) is the fastest of the monitors -- and also the fastest lizard ever recorded.
