How two butterfly species have evolved exactly the same striking wing color and pattern has intrigued biologists since Darwin's day.
The Granular Poison Frog (Oophaga granulifera) is a species of frog belonging to the family Dendrobatidae, found in Costa Rica and Panama. Its natural habitats are tropical and subtropical, moist, lowland forests, but it's threatened by habitat loss. This frog has been switched from Dendrobates granuliferus to Oophaga granulifera.
