What makes a scorpion glow under ultraviolet light, and how does its fluorescent nature benefit the scorpion in its environment?

Scorpions glow under ultraviolet light due to special proteins in their exoskeleton that react to the light. This fluorescence helps scorpions detect prey, navigate in the dark, and communicate with other scorpions. It also serves as a defense mechanism, as the glowing can startle predators or warn them of the scorpion's venomous nature.
