About Yellow monitor
What is the Yellow Monitor?
The Yellow monitor, scientifically known as Varanus flavescens, is a medium-sized monitor lizard native to South Asia. It is also commonly referred to as the golden monitor. This species is found within the floodplains of major river systems, including the Indus, Ganges, and Brahmaputra rivers, across India, Pakistan, Nepal, and Bangladesh.
Description and Habitat
Adult Yellow monitors typically measure between 45 and 95 cm in length, including their tail, and can weigh up to 1.45 kg. Their coloration ranges from olive to yellowish-brown above, often featuring irregular darker markings that can form broad cross bars. A distinctive blackish streak is usually present on the temporal region. The lower surfaces are yellowish with less distinct brown cross bars, particularly on the throat. Young individuals display a darker brown coloration with yellow spots that merge into crossbars. They inhabit wet areas, forest edges, and are often found in the vicinity of human settlements and agricultural lands.
Behavior and Ecology
As a diurnal lizard, the Yellow monitor regulates its body temperature by moving between sunny and shady spots. There is a notable report of one individual seeking warmth from a pile of hot ash from a human-lit fire. The species has also exhibited intriguing behaviors, such as swimming vertically and floating motionlessly in water, suggesting potential play behavior.
Conservation Concerns
The Yellow monitor faces significant threats, primarily from hunting for its meat and skin. Its preferred habitat is also under pressure due to human encroachment, pollution, and land conversion for landfills. In some regions, such as Kanchanpur District in Nepal, direct killing is a major threat driven by local fear of the species. Beyond consumption and skin trade, it is also utilized for medicinal purposes.
Legal Protection
International trade involving the Yellow monitor is strictly regulated under Appendix I of CITES. Furthermore, it is afforded legal protection within its range countries: listed under Schedule I of India's Wild Life (Protection) Act, 1972; Nepal's National Parks and Wildlife Conservation Act 1973; and Bangladesh's Wildlife (Conservation and Security) Act 2012.
