What purpose is attributed to the dark dorsal coloration of the Yellow-bellied Sea Snake when near the surface?
Answer
Camouflage from above against the darker depths of the ocean.
The striking tri-coloration serves specific defensive and camouflage functions based on perspective. The dorsal side, which is dark, typically black or dark brown, provides disruptive coloration when viewed from above, making the snake difficult to spot against the backdrop of the darker, deeper ocean waters below the surface layer. This countershading strategy is vital for avoiding avian or surface-level predators.
