The
Purple Frog is a product of isolated evolution that has been taking
place for over 130 million years. Evolving from the amphibian family Nasikabatrachidae,
the Purple Frog is a very recent discovery, having being discovered in
India in 2003 making the Purple Frog the first new family of frogs to be
discovered since 1926. Currently the Purple frog is listed as
endangered because the growth of deforestation is destroying its
habitat. It is believed that the Purple Frog and its closest relative
the Sooglossidae family’s ancestors shared that earth with dinosaurs
for around 70 million years before splitting down two distinct
evolutionary paths all before the firt human ancestors even emerged.
Although
you would have to be extremely lucky to come across a Purple Frog (as
only 135 have been recorded), the Purple Frog should be easy to identify
due to its unique characteristics. Reaching around 7 centimeters in
length the Purple Frog has a mixed coloration of purple and gray and is
somewhat bloated in appearance. The head of the Purple Frog is very
small compared to its body an the same is true with its limbs. As the
Purple Frog spends most of its life underground it is an expert burrower
making use of growths on its hind limbs to aid in burrowing.
The
only time the Purple Frog emerges from underground is in the monsoon
season where they emerge to mate. At this time both male and female
Purple Frogs can be observed collection in ponds or the banks of streams
(although there have only been 3 recorded females observed) where they
will breed and the larger female will lay her eggs in the pond or
stream.
The diet of the Purple Frog is almost exclusively termites
with the exception of the occasional worms and ants. The pronounced
snout of the Purple Frog works as a kind of ‘battering ram’ which they
use to break their way into underground termite mounds. Purple Frogs do
not emerge to hunt, all hunting takes place underground and the Purple
Frog most likely rely on smell for hunting as they have very poor
eyesight. Purple Frogs live in close proximity to their regular termite
prey as this provides easy hunting and is also beneficial to the Purple
Frog as the conditioned soil around a termite mound provides a better
habitat for the Purple Frog then that of regular soil.
