Taxonomy

In 2006, a group of amphibian scientists looked at the way scientists put frogs into groups. They changed some of the groups. They took some frogs that had been in the groups Dendrobates, Minyobates, and Phyllobates and put them in Ranitomeya instead.[2] In 2011, another team of scientists made the group Andinobates for 12 frogs that had been in Ranitomeya.[3]

Ranitomeya and Andinobates frogs are different from frogs in Dendrobates: They are smaller, have more than two colors, and look like glitter. Ranitomeya frogs live in the Amazon basin, and Andinobates frogs live in the northern Andes mountains and in Central America.

Body

Adult frogs are 21 mm (0.83 in) or smaller from nose to rear end and their skin is bright colors, for example bright yellow, red, or green on the back with stripes or dots. The throat also has color, usually yellow, orange or red. The head is narrower than the body. There are disks on the toes of all four feet for climbing. The disks on the front feet are larger than the disks on the back feet.[3] Some species, for example R. Variabilis, have tadpoles that eat each other.[4]

Danger

Many Ranitomeya species could die out because human beings change the places where they live and catch them to sell as pets.[5][6][7]

Species

There are 16 species of frog in the genus Ranitomeya:[1][8]
