In a movement reminiscent of breaching in whales, an elephant draws its head and chest up out of the water into a vertical position (as if sitting), and then, while raising the trunk over the head and leaning back, allows the body to splash backwards or sideways into the water and submerges such that the head and/or entire body is completely below the surface of an area of water.
A mother with a newborn and two juvenile females are playing in a pool with other elephants in the background. The female on the right rears up and then splashes into the water and submerges under the surface. (Amboseli, Kenya)
