"Macroinvertebrate" Natural Recordings by Native Speakers
Macroinvertebrates are invertebrate animals, such as insects, crustaceans, and mollusks, that lack a backbone, and have a body size of at least one millimeter. They are often found in aquatic environments, such as streams, rivers, and lakes, and play important roles in ecosystem functioning, serving as food sources for fish and other animals, and helping to break down organic matter.
