There are four different types of planktonic algae found in Kentucky: blue-green, brown, green, and Euglena. These can be distinguished from other plant types because they do not have a multicellular structure like regular plants and many other algae, and they can tint pond water different colors.
Below are pictures of the four types of planktonic algae, with links to their individual pages.
Blue-green algae form a skim on the surface that can be light green, dark green, blue, or even white.
Brown algae are free-floating in the water column; the water itself appears brown.
Green algae are free-floating in the water column; the water itself appears green.
Euglena are unicellular organisms that have characteristics of both plants and animals.
