It lacks legs and has a long tail, which it uses to swim. The tadpole also has gills to absorb oxygen from water. As the larva undergoes metamorphosis , it grows legs, loses its tail, and develops lungs. These changes prepare it for life on land as an adult frog. Frog Development: From Tadpole to Adult. A frog larva tadpole goes through many changes by adulthood. Notice the visible changes that occur at each stage. How do these changes prepare it for life as an adult frog?

Salamanders are nocturnal, hiding under logs and leaf litter. With the onset of freezing temperatures in late autumn, amphibians retreat to their hibernating sites. In winter, northern amphibians survive by hibernating underground, in ponds or under leaf litter beneath a thick blanket of insulating snow. Wood Frogs and Boreal Chorus Frogs, for example, use glucose in their cells as antifreeze that prevents the cells from bursting in these freezing temperatures.

Northern amphibians take full advantage of the warmth of the spring and summer sun. Eggs are large and dark to help absorb heat. They are submerged in warmer shallow water, safely below the surface, which might freeze. Tadpoles love to bask in the sun in the shallow while adult frogs and toads bask on land or in shallow water in the heat of the day.

Some amphibians, which are nocturnal in warmer climates, prefer the warmest and brightest part of the day in the North. This is for the third time in recent past that new species have been found in Maharashtra. Earlier, BNHS scientists had discovered an all new species of lizard near Junnar in Pune district and also rediscovered Indian egg eater snake, considered to be extinct, near Wardha in Vidarbha.

The discovery is part of the research project on conservation of herpetofauna — amphibians and reptiles living in a particular geographical area — in the northern Western Ghats, which BNHS started in
