Panamanian Golden Frog
These bright yellow and black-spotted frogs were once found in the fast-moving forest streams of Central Panama. They’re visual hunters, using their highly developed sense of sight to find prey during the day, which consists mostly of insects and other small invertebrates. Considered symbols of good fortune, these small amphibians are celebrated on National Golden Frog Day (August 14), which includes festivals and parades in the streets. However, thanks to their ability to synthesize toxins found in some of their prey, these famed frogs are extremely poisonous to humans and other animals. Their brilliant yellow color is a warning to all would-be predators of this toxicity.
