Insects & Arachnids
Insects are a group of invertebrates that live in the phylum hexapoda. Hexa- meaning six, and poda- meaning legs/feet, because insects have six legs! They also have an exoskeleton, or a protective shell, on the outside of their body. Arachnids, or spiders, are close relatives to insects, but have eight legs.
