Russell's viper is a large venomous snake with a characteristic pattern of light chains on its back. It lives in South and Southeast Asia and is considered one of the most dangerous snakes in the region.
Russell's viper differs from other vipers by its very potent venom that destroys tissues and blood, and a special chain-like pattern on its back. It helps control the rodent population in nature but often bites people working in the fields.
Immature form that undergoes metamorphosis before adulthood.
