Purple Frog
Nasikabatrachus sahyadrensis is a frog species belonging to
the family Sooglossidae. It can be found in the Western Ghats India. NAMES IN English
that have been used for this species are purple frog.
Indian purple
frog or pig nose frog. Although the adult frog was formally described in October
2003, the taxon was recognized much earlier by its tadpole, which had been
described in 1918.
Earlier
thought to be restricted to the south of the Palghat Gap in the Western Ghats,
additional records have extended its known range further north of the gap. The species
is now known to be quite widely distributed in the Western Ghats, ranging from
the Camel’s hump hill range in the north, all the way to the northernmost
portions of the Agasthyamalai hill range in the south.
The body of nasikabatrachus sahyadrensis appears robust and bloated and is relatively rounded compared to other more dorsoventrally-flattened flogs. Its arms and legs splay out in the standard anuran body form. Compared to other flogs, N. sahyadrensis has a small head and an unusual, pointed snout.
Adults are
typically dark purplish-gray in color. Males are about a third of the length of
females. The specimen with which the species was seven centimeters long from
the tip of the snout to the vent.
Unlike many
other burrowing species of frogs that emerge and feed above the ground, this
species has been found to forage underground their tongue and a special buccal
groove.
