Professor Anna Nekaris and a team of researchers has conducted the first ever study showing that the wild nocturnal primate, the Javan Slow Loris (Nycticebus javanicus), communicates in pure ultrasound, which is inaudible to the human ear. Before the discovery, it was commonly thought that slow lorises are almost silent. The study involved following the animals throughout their active periods.
