On a sunset cruise on Botswana's Chobe river, there is no shortage of elephants.
The river provides spectacular opportunities for photography.

Elephants produce large quantities of droppings every few hours and they have a very poor digestive system — even a healthy elephant only digests about 40% of what it eats

One can see by looking at elephant dung exactly what it has been eating, unlike the thoroughly processed droppings of ruminants with their 4 stomachs

Twigs, leaves, and a great many seeds pass through the elephants digestive system virtually untouched, which has profound ecological implications

Seeds that have passed through the stomachs of animals grow at twice the speed of those from your local nursery. ( Only the invisible maker knows why)
