Arthropods

Grasshoppers are interesting insects because they have an exoskeleton. I find that interesting because they can take off there exoskeleton when they are growing and developing. Also, the three pairs of legs  and their hind legs are the most powerful. The short-horned grasshoppers can "sing" by rubbing their hind legs together which no other insect can do. Grasshoppers have ears on their bellies, on each side of the first segment. Another thing that is interesting is that fossils have been found that they existing long before dinosaurs. Lastly, they spit brown liquid to defend themselves. The abdomen contains most of the organs. The three distinct facts are they have an exoskeleton, made of chitin, jointed body and two pairs of appendages.
