The Reddest Algae
The eight-place entry is by Nathanaël Prunet, a biologist at the University of North Carolina at Chapel Hill. It shows the tip of a species of red algae. These algae primarily live in seawater environments. Like many algae, these species are not technically considered plants, though they do share several features in common, such as the use of chlorophyll for photosynthesis. Humans have long used them as a source of food and natural dyes.
