A killer whale identifies a Weddell seal resting on an ice floe off the western Antarctic Peninsula. The whale will notify other killer whales in the area so they can coordinate a wave to wash the seal off the floe.

The endangered Caspian Seal (Pusa caspica) occurs throughout the Caspian Sea, using the winter ice sheets as a surface on which to give birth and nurse pups. Its population has declined by 90 percent over the last 100 years due to unsustainable levels of commercial hunting, habitat degradation and pollution.
