Macroinvertebrates

Small animal that has no backbone or internal skeleton large enough to be visible to the naked eye (>500┬Ám), such as insects, freshwater crayfish, worms, and snails.

Macroinvertebrates are sampled to provide an indication of stream water quality. Generally, the greater the diversity, the better the water quality in the stream.
