Why are so many sea snakes striped? University of Sydney scientists say solid black sea snakes may be at a disadvantage: they are coated with more algae, which slows them down. In underwater lab tests algae bloomed faster on all-dark surfaces, the scientists found; such fuzz causes so much drag it reduces the serpents’ speed by about 20 percent. No wonder black, algae-covered snakes are more often found skulking in coral hideaways than out-and-about striped snakes.
