| Although most marine fishes studied thus far cannot detect sound frequencies above about 500 Hz, at least some clupeids can detect considerably higher frequencies. |
| The open water expanses of the lake have been occupied mainly by two species of clupeids, as well as by Eutropius niloticus and Physailia pellucida. |
| Herring and other clupeids such as pilchards and sardines have a sophisticated auditory system. |
