I met Shaji uncle during my first visit to Peria forest range of Waynad. In the very first meeting I came to know of his experience and understanding with regard to kerala’s wildlife. Since then I’ve been going around the forests of Waynad with shaji uncle. What he lacks in scientific knowledge, he makes up for with his experience. I was even more surprised when i came to know that Shaji uncles brother, Babu also had a similar affection towards nature. Their interesting observations is what drives me to search for the lesser known herpetofauna of Kerala.

However, many intermediate cases exist and the distinction between viviparity and ovoviviparity is often academic.
Vomeronasal organ. Also known as Jacobson;s organ (q.v.). A chemosensory organ in the roof of the mouth of many vertebrates including reptiles and mammals. It is often thought of as a supplemental olfactory system that specializes in the detection of pheromones.
Reptiles and amphibians are one of the most fascinating creatures on our planet. But most of us fail to realise this. This blog is created to develop an interest to observe and appreciate them in their natural habitats.

Its nice to know more about genus Cnemapsis and its endemism in Western ghats.Thank you for making me aware of this. As we are all aware that, they are very sensitive to habitat alterations similar to amphibians, we need to urge for their conservation by efficient habitat management.
ReplyDeleteVery true sir. As long as we don't take things seriously, several species may be lost forever in the coming years. Thanks to people like Mr Girish and many others in this field, the herpetofauna of western ghats seems to have a brighter future.
ReplyDeleteCan you please help ID these lizards?
