Gerres

Gerres is a genus of mojarras found mostly in coastal regions from the eastern Atlantic Ocean through the Indian Ocean to the western Pacific. A single species, G. simillimus, is from the East Pacific. They mainly inhabit salt and brackish waters, but will enter fresh water. At least one species, Gerres cinereus (yellowfin mojarra), displays an ability akin to gyroscopic stability, allowing it to remain in a remarkably static spatial position relative to the water flowing around it.[1]
