Spiders come in all shapes, sizes and colors. They can be smaller than a grain of sand or larger than a dinner plate. Some have fuzzy, rainbow-colored bodies, while others are black and shiny. But even though they sometimes look like insects, spiders are in their own special group! We asked wildlife ecologist Thaddeus McRae how spiders and insects are different.
