Costa Rica's Osa Peninsula has to be the most biologically diverse spot in the country, home to nearly half of the country's flora and fauna. Amongst all the creatures is the striking Golfo Dulce poison dart frog, Phyllobates vittatus, which is distinguished by the unique red stripes along the sides of its body, contrasting strongly against the black color of its back. This frog's skin holds a powerful neurotoxin that can be seriously poisonous, possibly even causing seizures and paralysis.
8. Gelada - Ethiopia
This particular monkey species, the Gelada, Theropithecus gelada, is endemic to the highlands of Ethiopia, where it can be found sitting in fields chewing on grass. Its baboon- features and the red bare-skin triangles found on the chests of both males and females give this beautiful species its identity. At night, the Geladas climb cliff faces in search for the right ledges to sleep on.
