Nothing screams tropical rainforest like a poison dart frog. The colorful creatures, with their sticky little fingers and toes, are joined by tree frogs, bull frogs, horned frogs and giant toads in Frogs: A Chorus of Colors. It's as close as Columbus gets to Costa Rica.

The colorful creatures, with their sticky little fingers and toes, are joined by tree frogs, bull frogs, horned frogs and giant toads in Frogs: A Chorus of Colors. It's as close as Columbus gets to Costa Rica.

The COSI exhibit includes a number of living species in their aquarium ecosystems, presenting all aspects of frog life and their interactions with humans. This includes videos of frogs in the wild, information about the dangers they face in that habitat, plus stations where visitors can listen to frog calls and perform a virtual dissection.

The space is surrounded by "all of these amazingly gorgeous photographs by world-renowned wildlife photographers," said spokeswoman Kelli Nowinsky, who called the photos her favorite part. The exhibit runs through May 17.
