Tui De Roy is the lead author in a paper published in the scientific journal Ecology & Evolution which is dedicated to a rare behavior she witnessed off Santiago Island in the Galapagos. From out at sea groups of Galapagos sea lion cooperatively herd schools of Amberstripe scad fish into shallow coves and then flush them on to the shore. By corralling then beaching the fish the pinnipeds can easily trap and feed on their prey. You see in this gallery that Pelicans benefit as well, opportunistically feeding on the confused and landlocked scad.
