What is the primary function of the lighter colored tail tip in the Candoia aspera?

Answer

Caudal luring to attract prey

The lighter-colored tip of the tail is used for a behavior called caudal luring. While the snake remains perfectly still and hidden within its environment, it subtly wiggles its tail to mimic the movement of small prey, which lures animals like rodents or frogs close enough for the snake to quickly ambush them.
