Bottom feeders play an important role in aquatic ecosystems by feeding on detritus and other organic matter that falls to the bottom of the water body. They help to keep the water clean and provide food for other animals, such as fish and birds.
Here is a table of the average lifespans of some common bottom feeders:
| Bottom Feeder | Lifespan |
|---|---|
| Catfish | 50-70 years |
| Eel | 20-30 years |
| Minnow | 1-3 years |
| Darter | 2-4 years |
| Sculpin | 5-10 years |
| Sucker | 10-15 years |
| Flounder | 8-10 years |
