Sea Otters Practice Their Porpoising

These two are Sekiu and Mishka at Seattle Aquarium! The aquarium writes:

Sea otters Sekiu and Mishka [are] porpoise diving as they play in one of three sea otter habitats at the Seattle Aquarium. Sea otters will use this dive behavior not just for play but as a way to dive under the water when searching for food. In the wild sea otters might perform this type of dive behavior not only for foraging or play but also as a way to quickly get away from and avoid a predator.
