Craig Sholley, wildlife biologist and vice president of the African Wildlife Foundation, says genets likely jump on big herbivores to search for food.
For one, the genet eats insects that the rhino stirs up from the grass, the same technique cattle egrets use on grazing mammals. Sholley says it's also possible the nocturnal genet was searching for ticks that latch onto rhinos and buffaloes.
The rhino also offers the nocturnal, tree-dwelling animal a vantage point from which to scan for their prey, which includes anything from a dung beetle to a baby antelope.
Perching on a large, slow-moving animal could be a great hunting technique—until that animal-turned-lookout gets fed up.
