What are invertebrates?
Invertebrates are animals without a backbone or bony skeleton.
They range in size from microscopic mites and almost invisible flies to giant squid with soccer-ball-size eyes.
This is by far the largest group in the animal kingdom: 97 percent of all animals are invertebrates. So far, 1.25 million species have been described, most of which are insects, and there are millions more to be discovered.
Insects in particular are successful because they are so adaptable. They are opportunistic eaters, feeding on plants, animals, and decaying organic material. They are able to survive in extreme environments, including very hot, dry habitats. And many can fly—either to escape predators or to find new sources of food, water, and shelter.
