Thanks to Shrimp, These Waters Stay Fresh and Clean

Many people want to help protect our oceans—but what about our lakes, streams, ponds, and rivers? Despite making up less than half a percent of the world’s total water supply, freshwater is the lifeblood of human civilizations and critical aquatic ecosystems. Fortunately for us, there is a diverse array of biota working hard to keep these vital waters clean and healthy. In this short film by Freshwaters Illustrated, dive into a busy tropical stream ecosystem and learn how shrimp, crabs, and other invertebrates are creating a nutrient-rich environment for wildlife to flourish and humans to enjoy.
