Compound eyes vary in shape and protuberance. Insects have a single blood vessel that runs from their heads to their abdomens (the red line in the diagram), and the cells in their blood vessels divide into chambers. The tail of a grasshopper is divided into segments with the heart, reproductive organs, and most of the digestive system. Or that some grasshoppers have the ability to morph into swarming, destructive locusts? These furrows, known as sulci, cut into the median carina and divide the disk into zones, the prozona in front and the metazona in the rear. Theyre tiny; theyve got small mouthparts.
