Boophis

They show typical 'tree frog' traits, and are a good example of convergent evolution with morphologically similar species in the families Hylidae and Rhacophoridae, among others.

[1] The genus Boophis was described by Johann Jakob von Tschudi in 1838.

[1] Boophis are especially characterised by bright colouration of the iris, which is typically intricately patterned towards its inside, and often green or blue, but occasionally also red, purple, or yellow in the outer iris area.

Many species of Boophis have almost translucent skin, allowing bones and internal organs to be observed as in the unrelated glass frogs (Centrolenidae) of the tropical Americas.

Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than boophis.
