A whip-like straw.Powerful, crushing blades.A pointed, piercing tube.There are nearly a million known insect species in the world,but most have one of just five common types of mouthparts.And that’s extremely useful to scientistsbecause when they encounter an unfamiliar insect in the wild,they can learn a lot about it just by examining how it eats.Scientific classification, or taxonomy,is used to organize all living things into seven levels:kingdom,phylum,class,order,family,genus,and species.
