Tiny, colorful, pretty and deadly: the poison dart frog is arguably the world’s most lethal animal. Their poison is used in blowgun darts by native peoples of South America. Want to know the cool trick (ok, it’s really science) behind how our staff can handle them?
Well, here at the Museum, we feed the dart frogs crickets and fruit flies. In tropical forests, they get their toxin from other kinds of insect prey, probably ants and mites. As long as they aren’t eating those kinds of bugs, they’re not poisonous, so we can touch them.
In our lush, re-created habitats, you can observe these amphibians, as small as your fingertip, shining and vibrant. Imagine you are one of the Emberá people in Columbia, in search of this tiny creature for its toxic secretions for poisoning darts used in blowguns. Poisoned tips will help in hunting small prey faster.
Yet the story of these gems of the rainforest goes beyond poisons and blowguns, with larger lessons about biological diversity.
Birds and reptiles quickly learn to avoid the nasty tasting frogs, who display their toxicity with brilliant colors and striking patterns. The strategy is so effective that an entire second suite of frog species mimics the colors and sizes of dart frogs. These imitators aren’t toxic in the least, but ride on the coattails of those that are.
They don’t have to hide high in trees, and can be active in daytime, near the ground, where prey is more abundant. And they are among the few amphibians that can pair up and care for their offspring together.
Who'd imagine that poison could help with good parenting?

Enter through a neo-Gothic portal and learn about the upside-down world of bats! The exhibit includes multi-sensory interactive displays, and lifelike models. Lose your misconceptions about these night creatures and discover their ecological importance as well as the true wonders of the bat world.
Tauna Powell, a senior wildlife specialist at the Museum said, “Bats have a bad reputation and are misunderstood by many, but they play an important role in the ecosystem. In the High Desert, some species of bats eat 600 to 1,000 mosquitoes in just one hour.”
