The long-tailed snake Philodryas chamissonis lives in Chile and western Argentina. It is a slender diurnal snake with a very long tail that moves quickly and hunts small animals.
The long-tailed snake is distinguished by its very long tail and fast movement through bushes. It is important for nature because it controls the population of lizards and rodents.
Immature form that undergoes metamorphosis before adulthood.
