  • Iowa’s Nature Series – Aquatic EnvironmentsFrom the ephemeral pool of a prairie pothole to the giant pools of the mighty Mississippi, Iowa’s lands are defined by their diverse, and critically important aquatic ecosystems. 


Aquatic plants are essential in aquatic ecosystems. They provide oxygen, food, shelter, and protect shorelines and stream banks from eroding. They have a variety of adaptations to living in, on or near water and are divided into several groups.



Invertebrates are the least conspicuous, but most abundant, animal group. They range in size from microscopic to larger than a baseball. Invertebrates found in Iowa waters range from freshwater sponges to worms and crustaceans (scuds, copepods, and crayfish), mollusks (mussels and snails), arachnids (spiders, ticks, and mites), and insects.
