Macroinvertebrates are organisms that are large enough to be seen with the naked eye and lack a backbone which is invertebrate. They inhabit all types of running waters, from fast-flowing mountain streams to slow-moving muddy rivers. Examples of aquatic macroinvertebrates include insects in their larval or nymph form, mussels, snails, and worms. They are commonly found attached to submerged rocks, logs, and vegetation.
