Definition of bioindicator
- Bats are what naturalists call bioindicators: they indicate the state of the environment. If you see them, it means the air and water around you are healthy.

- The team compared two approaches to water-quality testing: measurement of pH and dissolved oxygen levels, and the use of bioindicators (using measures of the abundance and types of stream organisms present).

- Oysters, like other bivalves, are sessile organisms that are continually filtering water, and they often bioaccumulate toxins, making them ideal bioindicator species.
