This week we'll take a look at the creepy crawly world of spiders. Dr. Norm Platnick, curator emeritus in the Museum’s Division of Invertebrate Zoology, and Hazel Davies, Associate Director of Living Exhibits at the American Museum of Natural History, talk about spiders, which are among the most versatile animals on the planet—they're able to inhabit every continent but Antarctica and are able to survive in environments that range from deserts to rainforests to crowded cities. There's an exhibition at the American Museum of Natural History called "Spiders Alive!" It's on view through December 2.
