Other small carnivores caught on camera were the Sunda stink-badger (Mydaus javanensis), and two species of mongoose, the very common Short-tailed mongoose (Herpestes brachyurus) and the Collared mongoose (H. semitorquatus), and all three Bornean otter species, the Smooth-coated otter (Lutrogale perspicillata), Asian small-clawed otter (Aonyx cinereus) and the extremely elusive Hairy-nosed otter, considered to be the world's rarest otter.
