CCMB Study Monitor Lizards

To help preserve them and understand the genetic makeup of these ancient species, geneticists at CCMB in Hyderabad have initiated a unique study.

Hyderabad: Modern monitor lizards are descended from ancient lizards that once roamed the Earth millions of years ago. Although the species has survived for millions of years through continuous evolution, their numbers have definitely been declining in the recent past.

To help preserve them and understand the genetic makeup of these ancient species, geneticists at the Center for Cellular and Molecular Biology (CCMB) in Hyderabad have initiated a unique study.

Led by CCMB Senior Principal Scientist Ajay Gaur, the genetic research team has begun efforts to generate the complete mitochondrial sequence of the Indian monitor lizard. In fact, the group’s preliminary data showed “clear distinctions between the different species in India based on the partial sequences of four mitochondrial genes”.

All remaining monitor lizards in the country are Schedule I species under India’s 1972 Wildlife Protection Act, which means they are endangered and vigorous efforts are needed to protect them. Schedule 1 also protects species from poaching, killing, trade and individuals who violate the schedule face the harshest penalties.

However, the common Indian monitor lizard, commonly known as the Bengal monitor lizard (Varanus bengalensis), is the most targeted species in the illegal animal trade. They were often held captive for their superstitious beliefs and often sold meat and body parts.

One of the biggest threats to monitor lizards is hunting for their skin, which they use to make their drums. The genitals of monitor lizards have been identified as the Hatha Jodi plant, which many believe has medicinal properties and is an aphrodisiac. Monitor lizard meat and eggs are also a delicacy in some parts of the country.

So far, there is no comprehensive scientific data information on the ecology and genetics of Indian monitor lizards. In fact, thorough phylogenetic studies are required to preserve this ancient species.

“With growing threats from illegal poaching, habitat loss, climate change and highly unresolved phylogenetic relationships within related species, more genetic information will need to be generated to reveal the unique biology of Indian monitor lizards,” CCMB researchers said in a report on Monitor. said the lizard.
