About Aquatic Invertebrates in Missouri
Missouri is home to thousands of kinds of animals without backbones that live in the water. Aquatic invertebrates may live entirely beneath the water, or they may live upon its surface or on the plants surrounding it. Some breathe air, others breathe water. To move, they may walk, swim, float, skate, fly or glide on their bellies—or they may not move much at all.
