Soon after the mating and egg laying adult frogs dig down to their underground burrows, the entire process may only take a couple of days even seeing a frog is therefore a huge challenge. A male frog on the back of the larger female during breeding These bulbous frogs lay their eggs in the crevices. Mating (in frogs this is known as amplexus) happens inside the tunnel and the females, who are double the size of the males, carry the male frogs on their backs to the egg laying sites which are crevices along the fast flowing torrential streams. At the start of these rains, male frogs come close to the surface and begin to call from the underground tunnels. Adult frogs perfectly time their emergence from underground with the early rains when their egg laying sites are inundated by seasonal streams which begin to flow. Purple frog female carrying a male frog back to its egg laying siteīeing fossorial (living underground), it took a long time for scientists to understand their ecology. It is living evidence for the Gondwanaland hypothesis due to its relation to the frogs in the family Sooglossidae that are restricted to the Seychelles archipelago indicating that these land masses were once connected. This species has been independently evolving for 130 million years. This is quite a challenge! The Purple Frog Nasikabatrachus sahyadrensis is the sole member of Nasikabatrachidae, the first new frog family described since 1926. There are protected areas nearby, but so far they have not been observed inside of them.During mating, purple frog females who are double the size of males, carry the male frogs on their backs to egg laying sites.īeing a biologist from Kerala in the Western Ghats I am trying to understand and conserve a species of frog that emerges from the underworld only once every year like the great Hindu King Mahabali. They have a very small range that is threatened by agriculture and deforestation. Sadly, the Purple Frog is considered Endangered. Unsurprisingly, they feed on termites and other subterranean insects. They sometimes dig tunnels as deep as 10ft below the surface! The Purple Frogs only emerge for a few weeks each year in order to mate. They are small, maxing out at around 7cm, and they live almost entirely underground. Now, it's not wonder that it took until 2003 for the Purple Frog to be discovered. That is why today the only members of the Sooglossidae family live so far apart! As the landmass continued to drift, pieces gradually (over millions of years) broke off, and the Seychelles and India became separated. Once upon a time the common ancestor of the Purple Frog and their Seychelles cousins lived on a landmass that split away from Gondwana, the southern supercontinent. But amazingly, their closest relatives live over 1,500 miles away in the Seychelles. You'll find the Purple Frogs in a very small range in southern India. The Purple Frog is an incredibly fascinating amphibian- not only are they one of the most recent frogs to be discovered by science, but they are also members of a family that has lasted for over 130 million years!
