The highlight of this excellent natural-history museum is the expansive Butterfly Rainforest (adult/child $13/6). Hundreds of butterflies from 55 to 65 species flutter freely in the soaring, screened vivarium. As you stroll among waterfalls and tropical foliage, peek at scientists preparing specimens in the rearing lab of this, the world's largest butterfly research facility. Other exhibits include displays on fossils and Floridian ecosystems.
