Purple frog (Nasikabatrachus sahyadrensis)

The purple frog is the sole representative of an ancient lineage of frogs that has been evolving independently for over 130 million years. Its closest relatives are the Seychelles frogs, the ancestors of which were present on the Indo-Madagascan land mass with the purple frog’s predecessors when it broke away from the supercontinent of Gondwana 120 million years ago. Formally discovered in 2003, the purple frog spends most of the year underground, surfacing only to breed during the monsoon. It was the first new family of frogs to be discovered since 1926. This species is threatened by ongoing forest loss for coffee, cardamom and ginger plantations.
The purple frog is a relatively large burrowing frog with a distinct, bloated or plump appearance. The head is conical and short in comparison with the rest of the body, and has a white, protruding snout. The fore- and hind-limbs are short, ending in partially webbed feet with rounded toes and each hind foot possesses a large, white wart-like growth, most likely used for digging. The eyes are small, rounded, and have a horizontal pupil. This species has smooth, dark purple skin that fades into grey along the stomach. Purple frogs reach a total length of about 7 cm.
The purple frog spends most of the year underground, surfacing only for about two weeks during the monsoon season in order to mate. It lives 1.3-3.7m below ground and the frog's reclusive fossorial (digging or burrowing) lifestyle is what caused the species to escape earlier detection by biologists. It comes to the surface for a few weeks a year to breed in temporary and permanent ponds and ditches. During the breeding season, local people reported seeing purple frogs in the vicinity of water pools or at the sides of the swelling streams in pairs clasping each other, especially at the beginning of the monsoon season. During mating, the male clasps the female from behind just above the legs in a behaviour termed “inguinal amplexus”. The bloated shape of both male and female purple frogs, and the smaller size of the male, may mean that males partially glue themselves onto females using sticky skin secretions, as occurs in “short-headed frogs” in the family Brevicipitidae. Eggs are laid in water that hatch into tadpoles, often in ponds close to streams.

Purple frogs require damp, loose soil to borrow into, and may dig themselves fully into appropriate soil within 3 to 5 minutes. When placed on hard ground, pebbled- or gravel-strewn soil, or areas with a thick mat of weeds, purple frogs are unable to borrow effectively and go in search of cover. The hind limbs have strong feet with wart-like structures that are primarily used for digging. This frog burrows downwards using its hind limbs like spades, throwing the soil over its back. They rest underground in a horizontal position with the limbs tucked under the body, although they do not remain idle underneath the soil, especially when foraging for their prey.

Male purple frog calling

Aye, a must admit, it's no the bonniest frog in the pond Vinnie..


Thanks fur awe the interest, a thought it wiz amazing that they spent so much time burrowing under ground..


Here;s a wee bit more about it.....


The Purple Frog was discovered in October 2003.

It is also called Pignose Frog.

Compared to other frogs, The Purple Frog has a small head and a rather peculiar, pointed snout.

The diet of the purple frog predominantly consists of termites, and this species has a narrow mouth with a small gape, preventing it from catching and consuming larger prey items. Its strong head and pointed snout permits it to penetrate underground termite niches, and a fluted tongue may allow this species to suck up its prey from subterranean burrows. With its poor vision, this frog presumably depends on smell and tactile cues to detect and locate prey. It also consumes ants and small worms.

It can be found in the Western Ghats in India.

Also, its cry sounds more like one from a chicken. 


A hope you are all still behaving yersells fruddy buddies!!  A ALSO HOPE ALL FURBABIES,  FYRE,  DOTTIE, ETC ARE RECOVERING WELL!


Nice tae see ye pop in Martina
