Macroinvertebrates are a diverse group of animals, ranging from insects and crustaceans to molluscs and worms. They have been around for about 500 million years and some were even living in our waterways before the dinosaurs! Different aquatic macroinvertebrates have different tolerance levels to water pollution. Some water critters are sensitive to pollution, which means if the waterway was to become polluted they will die or move elsewhere. Other critters are tolerant to pollution, meaning they can survive in polluted water. By sampling a waterway for macroinvertebrates and identifying what’s there you will get a good indication of water quality and habitat condition. This word search contains the names of the different kinds of macroinvertebrate one might find in a typical freshwater stream. Good Luck!
