Discovered frog species extinct 20 years ago

An extinct published frog species 20 years ago suddenly found in the Monteverde rainforest reserve in Costa Rica.

The extremely rare female frog of the frog species, whose scientific name was Isthmohyla rivularis, was declared extinct 20 years ago, recently found by a film crew of British BBC television. This group has recorded some images of frogs that are certainly the rarest in the world.

Previously, in 2007, researchers at the University of Manchester (UK) claimed to have caught a glimpse of a frog-like male in a grove of trees, but could not find it.

Very rare female frog of the species Isthmohyla rivularis.

Finding females and males is a variant of this extinct Isthmohyla rivularis frog that allows scientists to claim that they are growing and will soon escape extinction if as humans have appropriate safeguards.

Andrew Gray, an expert at Manchester University, commented: "Currently, the presence of both males and females of the frog Isthmohyla rivularis still exists in the wild, forcing scientists to further research and provide measures to protect this amphibian. '

The BBC television crew was lucky enough to snatch the image of a female frog Isthmohyla rivularis at the Monteverde rainforest reserve in the Costa Rican Republic. This frog has a body of 2.5 cm long, brown skin with green spots. At the time of recording, the frog is preparing to lay eggs.

The findings give researchers hope for their adaptability and survival in any environmental condition.

Andrew Gray explained: 'Last year, when we saw a male, we were not sure if it was one of the last male breeds of this variation. But now, discovering a female has brought hope that this frog will soon escape the brink of extinction. However, at present, the number of frogs of this type is still very small. '

Scientists have been studying the new female frog's mucus to find out why this variant can exist while others do not.
