Just 10 miles away from Ecuador’s capital city Quito are the slopes the Andes shelter which is one of the most biologically diverse and threatened spots in the tropical area.
Here, two newly identified species of glass frogs were discovered in a river called the Guayllabamba. What is special about the frogs is that they are see-through!
This means that underneath, the frogs have a completely transparent belly which shows a red heart, textured white liver and digestive system. In females, the belly also shows a pouch of greenish eggs.
It turns out the two newly discovered frogs are of a different species, with both existing at roughly the same altitude in similar humidity and temperature conditions.
At just around 1.9 to 2.1 centimetres long, the bodies are nearly identical to the naked eye, with lime-green backs peppered by black dots arranged around yellow spots.
There are around 156 known species of glass frogs living throughout the neotropics. With researchers sequencing genes for about 90% of the 150 existing species for the past decade, this revealed that the two new discovered frogs diverge genetically by 5%.
Due to environmental differences between the habitats of the two species, the populations started to get an accumulation of different mutations, separating them genetically.
