Clupea is genus of planktivorous bony fish belonging to the family Clupeidae, commonly known as herrings. They are found in the shallow, temperate waters of the North Pacific and the North Atlantic oceans, including the Baltic Sea.

This species mating season typically falls in spring. These animals are in danger and facing threats because their water is drying out because of pumping of ground water for agricultural developments.
Fundulus zebrinus is a species of fish in the Fundulidae known by the common name plains killifish.
