Algae-Covered 'Dragon' Snake Shocks Internet: The Science Behind the Phenomenon

• An old video of an unusual, algae-covered snake from Thailand resurfaced, captivating and confusing internet users.
• The snake, found in 2022 by Tu in Sakhon Nakhon, Thailand, was covered in thick green algae, making it appear 'furry' or 'dragon-like'.
• Algae growth on snakes is common for water-dwelling species that remain still in nutrient-rich waters, providing camouflage and generally not causing harm.
• Heavy algae can slightly impede movement, but snakes shed their skin to remove it; toxic algal blooms do not seem to affect them.
• Darker, plain-colored marine snakes are more prone to algae growth than patterned freshwater species, aiding in camouflage for ambush predators.

Why It Matters: Algae-covered snakes are a real natural phenomenon, offering camouflage and rarely harming the reptile.
