Eleutherodactylus orientalis

Eleutherodactylus orientalis, the Oriental robber frog or Baracoa dwarf frog, is a species of frog in the family Eleutherodactylidae. It is endemic to the vicinity of El [Yunque (Cuba)|El Yunque], Baracoa, in easternmost Cuba. Although locally common, it requires undisturbed moist forest and has a tiny range, making it critically endangered from habitat loss and degradation.
E. orientalis is relatively brightly marked in yellow and very small, females averaging in snout–to–vent length and males. It is part of a closely related Cuban group that contains five additional described species and at least one undescribed species; most of which are of tiny size, relatively brightly colored and possibly aposematic.
