Venomous animals have evolved a variety of mechanisms that deliver toxins to would-be predators and prey. In this video, Museum Curator Mark Siddall explains some of the anatomical features you'll want to avoid.

At the American Museum of Natural History's exhibition, The Power of Poison, you'll learn how most venomous animals have two things in common: special glands for manufacturing venom and something sharp with which to inject it. You'll also get a chance to see some of the toxic species, including a Gila monster, flame caterpillars, and others, up close.

The Power of Poison is now open at the Museum, through August 10, 2014.
