The Ecological Importance of Rhino

As mega-herbivores, rhino’s are ecosystem engineers and ecological drivers that critically help shape the health of the wilderness so that other species may thrive. We therefore need to realise the true value that these animals play in a delicately balanced and inter-dependent ecosystem and that their loss will ultimately also negatively impact on numerous other species.

The larvae on hatching burrow inside the rhino and attach themselves to the stomach where they feed on the blood and tissue of the rhino. Because the fly depends on the rhino, its numbers declined steeply as rhino populations declined.

One of the insects regularly encountered was this Stolliana species of grasshopper.

This gecko species was found on several occasions on different rhino and presumably rides on the rhino’s to catch an easy meal from the numerous insects that are attracted to the rhinos.

11 of 12: Numerous species of dung beetles congregate in large numbers at elephant and rhino dung piles to collect the fresh dung that is then packed into tight balls and buried into tunnels where the eggs are laid and the larvae later feed upon the dung ball.

The dung beetle also will be carrying small parasites on the underside of its body. All of these species thrive as a result of the large mega herbivores that include the rhino.
