Gray whales feed benthically, by diving to the ocean floor and rolling on to their side, and suck up prey from the seafloor. When they feed planktonically, they roll onto their right side while their fluke remains above the surface, or they skim the surface with their mouth open. Gray whales can easily switch from feeding planktonically to benthically. They eat prey by turning on their side and scooping up sediments from the seafloor. Gray whales feed mainly during the long daylight hours of the summer months and often feed near the shore where the water is very shallow. They also “breach” (jumping up into the air then splashing down onto their back or side, known also as cresting or lunging), which is understood to be a form of communication, a form of play, and an attempt at removing skin parasites. They do this while looking out for predators or other whales.
