At first, the satellite images appear to be of grey blobs in a forest of green splotches - but, on closer inspection, those blobs are revealed as elephants wandering through the trees.
And scientists are using these images to count African elephants from space.
The pictures come from an Earth-observation satellite orbiting 600km (372 miles) above the planet's surface.
The breakthrough could allow up to 5,000 sq km of elephant habitat to be surveyed on a single cloud-free day.
