Definition of "clupeid"

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.

In the pelagic zone of Lake Tanganyika, the endemic clupeids are planktivores which migrate surfacewards at night (cf. marine clupeids, p. 227).

Although most marine fishes studied thus far cannot detect sound frequencies above about 500 Hz, at least some clupeids can detect considerably higher frequencies.
