Imagine a world without elephants.

Not only would we have lost one of the planet's most charismatic, extraordinary creatures,

also gone would be a network of ecosystem engineers, because elephants are

crucial for other creatures to exist. They disperse seeds in their copious droppings. By literally

cutting paths through forests as they trample trees and bushes, they create a more complex

landscape. And now we know that their very footprints are important.

We were walking through the forest in Kibala National Park, and that's when we stumbled

upon this water-filled elephant footprints.

University of Koblenz Landau ecologist Wolfram Remmers.

Well, we looked at them and we quickly noticed that they were not only filled by water, but there were lots of animals

living in them.

Remers and his colleagues discovered that elephant footprints are a critical habitat for aquatic

invertebrates like water beetles.

The team studied 30 footprints in different parts of the National Park in Uganda to see
