The Rockstone poison dart frog (Dendrobates nubeculosus) is a poorly known species of dendrobatid frogs endemic to Guyana. As it is known from only one specimen, very little information is currently available on D. nubeculosus. [1] [3] [4] [5] It has been suggested to be one of the most poorly known species in the world.

Dendrobates is a genus of poison dart frogs native to Central and South America. It once contained numerous species, but most originally placed in this genus have been split off into other genera such as Adelphobates, Ameerega, Andinobates, Epipedobates, Excidobates, Oophaga, Phyllobates and Ranitomeya (essentially all the brightly marked poison dart frogs; i.e. excluding the duller genera in ...
Their bright coloration is associated with their toxicity and levels of alkaloids. For example, frogs of the genus Dendrobates have high levels of alkaloids, whereas Colostethus species are cryptically colored and are not toxic. [4] Poison dart frogs are an example of an aposematic organism. Their bright coloration advertises unpalatability to ...
The Mantellidae are an amphibian family of the order Anura (frogs and toads), and are endemic to the Indian Ocean islands of Madagascar and Mayotte. [1] [2] At first glance, the diminutive, brightly-coloured mantellas appear visually similar to (and indeed fill similar ecological niches as) the Latin American poison dart frogs, such as Dendrobates, Oophaga and Phyllobates, among others.
