insectsInsects are the most abundant group of animals on earth, though none have ever been known to live in the ocean. They have unusual and amazing features, but all have 3 basic body parts; head, thorax, and abdomen. There are two antennae on the head which some insects use for smelling. Other insects taste with their feet. Insects have three pairs of legs; they do not have bones, their bodies are covered with an external skeleton and they do not have lungs, but breathe using a special system of tubes. See more information here
