More than 40,000 species of spiders exist worldwide, and approximately 3,500 species exist in the United States and Canada. Although arachnophobia (fear of spiders) is one of the most common phobias in North America and Europe, only about 30 species can harm humans. This 12-panel folding guide introduces you to the world of spiders; describes their evolution, anatomy and behaviour; and explains the ways in which spiders benefit healthy ecosystems and are useful to humanity. It also highlights both familiar and unusual species and provides steps to take in case of an encounter or venomous bite, as well as threats to spiders' survival and what you can do to help conserve and protect these species.
