Caterpillar Muscles

That's one seriously muscle-bound insect! By comparison, humans have just 629 muscles in a considerably larger body. The caterpillar's head capsule alone consists of 248 individual muscles, and about 70 muscles control each body segment. Remarkably, each of the 4,000 muscles is innervated by one or two neurons.
