A new species of frog discovered in the Amazon, with a secret hidden behind its back

A small frog species that can raise its eggs in a natural pouch on its back has been officially described by researchers around the world. peruvian amazonfurther documenting the diversity of amphibians living in one of South America’s most ecologically productive mountainous regions.

The discovery was announced in early April 2026 and published in a New Zealand scientific journal. zoo animals It was conducted in collaboration with Florida International University and the University of Seville, Spain. The species was identified by researchers affiliated with the Seja de Selva Institute for Sustainable Development, part of Peru’s National University of Toribio Rodríguez de Mendoza.

Unique reproductive strategies set species apart

Official name of newly described amphibian gastritisthe measurement between 2.7 and 3.3 It is centimeter long and has a bright green dorsal color and prominent round pustules covering its back. It was discovered in a subalpine páramo in Peru’s Amazonas department, in the Huancabamba region near the border with Ecuador.

What sets this frog apart in the wider frog world is its mode of reproduction. Most frog species rely on still or running water for egg development; gastritis They use their back pouches to carry and raise their young, which is a unique feature of this genus. stomach operculuma group of marsupial frogs native to Central and South America. According to research on zootaxa, Phylogenetic analysis Due to differences in mitochondrial and nuclear gene sequences, the new species Gastroteca Marspiata Species groups identified as sister species of G. trachyplevra.

Researchers distinguished it from related species by a combination of morphological features, including a thick, raised shape.supratympanic fold It is covered with dense pustules, two prominent pustular ridges running parallel to the spine, and narrow finger and toe discs with truncated tips. The study also reported the first recorded presence of related species. G. Turnernew morphological data on the Peruvian population of the species in Peru.

Manuel Oliva, director of the Seja de Selva Institute, told Agence France-Presse that the discovery reflects the depth of the region’s biodiversity, which is still awaiting formal documentation. “If we continue our research, there are many species still waiting to be discovered.” he said.

Habitat degradation poses an imminent threat

Despite the scientific interest generated by this discovery, researchers classify it as: gastritis like facing High maintenance risk. Habitat in the Huancabamba region is being degraded by a combination of climate change and fires used by farmers to clear land, pressures that are reducing and fragmenting the mountain ecosystems on which the species depends.

According to research, the Huancabamba region has become a hotspot for infectious diseases. stomach operculum Species richness, a pattern that researchers are discussing from a biogeographic and conservation perspective. Exact size of wild population G. Nonunion have not yet been identified and the lack of reliable population data makes it difficult to assess the scale of the threat faced.

The discovery adds to a broader pattern of amphibian species discovered in recent years in Peru, the Andes and the Amazon, where difficult terrain and limited research infrastructure have left large parts of the fauna undescribed. According to Seja de Selva Institutecontinued fieldwork in ecosystems like the subalpine páramo may lead to the creation of even more new species.

Amphibians are one of the world’s most endangered vertebrate groups, with populations declining on multiple continents due to habitat loss, disease, and climate change. Newly described species, especially those with limited ranges and specialized habitats, are often the most vulnerable from the moment they are formally identified.
