Opaskoirana

Opaskoirana is a genus of frogs belonging to the family Ranoidae. It is endemic to Madagascar and is characterized by its small size and distinctive appearance. The genus comprises a single species, Opaskoirana elongata, which was initially described in 2017.

The Opaskoirana genus is notable for its elongated body shape and narrow snout, a characteristic feature shared among its congeners. Adult individuals typically measure approximately 2.5 to 3.5 centimeters in length, with a slightly larger size in females. Its small size and remarkable unusual appearance result in it being one of the most discerning members of the Ranoidae family.

Opaskoirana elongata inhabit tropical regions ranging from high montane to humid lowland zones of the local biodiversity. They can be found in association with rainforests. The diet of Opaskoirana consists mainly of invertebrates, which are likely ingested in small quantities.

Opaskoiranas possess traits suggesting a generalist insectivorous diet rather than a specific feeding habit due to a diet that encompasses a diverse range of invertebrates. Their lack of distinct food item preferences corresponds to some specialized habits noticeable within their ranid counterparts. Opaskoiranas are only locally distributed and are recognized as one of the most limited ranids species on a global level, forming an endemic-dominated population known as a "total fady priority," making their dispersal limited due to no lack of abundant vegetation. These fady habitats enhance heightened drift stakes in baseline habitats often present and environmentally present, mentioned.
