Live spiders, centipedes, millipedes, and insects reside year-round in our Insect Zoo. All of these--plus crabs, shrimp, and lobsters--make up the group of animals known as arthropods. They account for up to 90 percent of all animal species. Over millions of years, insects have become the world's greatest success story. They have learned to flourish everywhere, from icy oceans to tropical rainforests, from hot deserts to our homes. Key to their success are high reproductive rates, short lifetimes, specialized ways of catching prey, raising their young, and protecting themselves. Learn how these fascinating animals are designed for survival and where they fit into the natural world.
