Bornean White-Bearded Gibbon
The Bornean white-bearded gibbon, (Hylobates albibarbis ), also known as the Bornean agile gibbon or southern gibbon, is a species of gibbon endemic to southern Borneo. It is an endangered species, due to the undergoing logging of the tropical forests, between the Kapuas and Barito rivers. Additional issues are of concern to the endangerment of white-bearded gibbons and threatening to other arboreal primates.The white-bearded gibbon is very ...
similar to other gibbons in their behaviour and their frugivorous diet. The Bornean white-bearded gibbon was formerly considered a subspecies of the agile gibbon but based on recent DNA research, some now classify it as a separate species.

Bornean flat-headed frog
The Bornean flat-headed frog (Barbourula kalimantanensis ) is a species of frog in the family Bombinatoridae. Although many salamanders are lungless, the Bornean flat-headed frog is the first frog known to have no lungs.Djoko Iskandar, an Indonesian zoologist, first described the Bornean flat-headed frog based on a single specimen. However, he did not know the frog was lungless until he was in the field with David Bickford's expedition. Bickford ...
et al. were able to dissect some of the specimens and discovered for the first time that the frogs had no lungs. The frog breathes entirely through its skin, and its internal organs (the stomach, spleen and the liver) take up much of the space which normally would be filled by the lungs. By retaining the lunglessness of their tadpole stage, the frogs are much flatter than typical frogs, which might help absorb oxygen and avoid being swept away in fast streams.

Nycticebus borneanus
Nycticebus borneanus, the Bornean slow loris, is a strepsirrhine primate and a species of slow loris that is native to central south Borneo in Indonesia. Formerly considered a subspecies or synonym of N. menagensis, it was promoted to full species status in 2013 when a study of museum specimens and photographs identified distinct facial markings, which helped to differentiate it as a separate species. It is distinguished by its dark, contrasting ...
facial features, as well as the shape and width of the stripes of its facial markings.As with other slow lorises, this arboreal and nocturnal species primarily eats insects, tree gum, nectar, and fruit and has a toxic bite, a unique feature among primates. Although not yet evaluated by the International Union for Conservation of Nature (IUCN), it is likely to be listed as "Vulnerable" or placed in a higher-risk category when its conservation status is assessed. It is primarily threatened by habitat loss and the illegal wildlife trade.
