This page contains pictures of some of the animals that I saw in Borneo. The pictures of the flora in Borneo are on a separate flora page.
The highlight in Borneo are the Orangutans, the second largest of the Great Apes. I visited the Sepilok Orangutan Rehabilitation Center in Sandakan to see my first Northeast Bornean Orangutan (Pongo pygmaeus morio, german: Borneo-Orang-Utan, french: Orang-outan de Bornéo). Here they raise young Orangutans that were rescued from illegal pet trade or found abandoned after poachers killed the mother. There they learn to live in the wild. If they are successful, they are released in the jungle. Sepilok has feedings at 10:00 and at 15:00, during which times you are basically guaranteed to see Orangutans (and other monkeys who steal the food from the Orangutans). I went to the 10:00 feeding with my guide. I was free for the afternoon, so I went to the 15:00 feeding as well. At the first feeding I saw only one Orangutan, at the afternoon feeding there were seven of them that were much more active.
Another highlight was watching a Green Sea Turtle lay her eggs in the Turtle Islands Marine Park. The three Malaysian Turtle Islands in the Marine Park, Pulau Selingaan, Pulau Gulisan, and Pulau Bakkungan Kecil, are a nesting area for Green Sea Turtles (Chelonia mydas, german: Grüne Meeresschildkröte, french: Tortue verte) and Hawksbill Sea Turtles (Eretmochelys imbricata, german: Echte Karettschildkröte, french: Tortue imbriquée). Since the nesting seasons for these two species are complimentary, you can watch sea turtles laying eggs basically all year long. The park rangers on the three islands monitor the beaches on these three islands every night for egg-laying females. While the turtles lay their eggs, the park rangers collect them, so the turtle covers an empty hole after she is done laying her eggs. The eggs are then transferred to a fenced hatching area for incubation. Once the baby turtles hatch, they are transferred back to the beach and released. My first question was: "Why don't you raise them for a while till they are big enough, so they have a better chance to survive". The simple answer is that they loose their migration instinct if they grow up in a fenced enclosure. They do not leave the island to grow up in the ocean and then return after some years to mate and lay eggs.
Each evening, the rangers select one nesting turtle for watching by tourists. The rangers briefed us in detail about what we can and cannot do, in order to not disturb the turtle during egg laying. The danger there is that she will abandon the egg laying and return to the ocean if she is disturbed. During the egg laying everybody has to stay behind the turtle so she cannot see us. Noise does not seem to be a problem, but flash photography is, so no flash. I was surprised that this really worked while I was there. Usually there are always a couple of klutzes who can't handle their camera and flash anyway, but this was not the case this time.
Once the egg laying is finished, the turtle will start covering the hole with sand. By that time, the ranger has already removed all the eggs, so the turtle covers an empty hole. The turtle that I was watching laid 97 eggs. At this time you can move around to the front of the turtle to take pictures (still no flash).
Egg laying is very strenuous for turtles and takes a long time. They take some ½ hour to find a spot for a nest. They then dig a hole for about one hour, lay eggs for ½ hour, and then cover the hole for another hour. Then they have the ½ hour trek back to the ocean. One female usually comes back to the beach 6-7 times in one season. She then goes back to the deep ocean for 2-3 years, before returning for another egg laying season. All the turtles are marked with metal tags when they lay eggs for the first time, and the rangers keep track of which turtle lays eggs when and how many.
One important draw for me were the primates, and in particular the apes. During my trip to Borneo I saw two more of the Apes species, Northeast Bornean Orangutans (Pongo pygmaeus morio, german: Borneo-Orang-Utan, french: Orang-outan de Bornéo) and North Bornean Gray Gibbon (Hylobates funereus, german: Müller-Gibbon, french: Gibbon de Müller). The Orangutans are the second largest of the Great Apes (after the Gorilla), the Gibbons are the smallest of the Apes. The Gibbons are purely arboreal, they never go to the ground. They are fantastic acrobats in the trees, and can easily leap between trees.
Other animals to see in the various rain forest areas in Borneo are many species of monkeys, birds, reptiles, amphibians, and insects.
The strangest looking of the primates is the the Proboscis Monkey (Nasalis larvatus, german: Nasenaffe, french: Long-nez), a species endemic to Borneo. Other monkeys are the Long-tailed Macaque (Macaca fascicularis, german: Javaneraffe, french: Macaque crabier), the Southern Pig-tailed Macaque (Macaca nemestrina, german: Südlicher Schweinsaffe, french: Macaque à queue de cochon), the Maroon Leaf Monkey, or Maroon Langur (Presbytis rubicunda, german: Maronenlangur, french: Semnopithèque rubicond). I also saw the Bornean Tarsier (Cephalopachus bancanus borneanus, german: Sunda-Koboldmaki, french: Tarsier de Bornéo). These night-active animals are very difficult to spot, because their eyes do not reflect light like those of most of the other animals do. They are therefore very difficult to locate.
In the Tabin Reserve I saw quite a few larger mammals during the night drives. I saw Bornean and Sumatran Leopard Cats (Prionailurus javanensis sumatranus, german: Sundakatze), several species of civet, and flying squirrels and Sunda Flying Lemurs (Galeopterus variegatus, german: Malaien-Gleitflieger, french: Galéopithèque de Temminck), no relation to the lemurs in Madagascar.
Reptiles are mostly lizards, but also some snakes. Most impressive here was the Southeast Asian Water Monitor (Varanus salvator macromaculatus, german: Bindenwaran, french: Varan malais), which can grow to impressive lengths. I saw a couple of them that were over 2 m (7 ft) long.
Amphibians are mostly out at night. I saw several species of frogs, including the strange looking Long-nosed Horned Frog (Pelobatrachus nasutus, german: Zipfelkrötenfrosch, french: Grenouille cornue asiatique).
There are lots of insects in the rain forest. The strangest looking one was the Southeast Asian Pill Millipede (Zephroniidae gen.) and the Lantern Bug (Pyrops sidereus).

North Bornean Gray Gibbon (Hylobates funereus, german: Müller-Gibbon, french: Gibbon de Müller)
North Bornean Gray Gibbon (Hylobates funereus, german: Müller-Gibbon, french: Gibbon de Müller), also known as the grey gibbon, is a primate in the gibbon family, Hylobatidae. It is endemic to Borneo.
Unlike other gibbon species, North Bornean Gray Gibbon does not show sexual dimorphism in its fur coloration. Its fur is grey- or brown-colored with a ring of bright fur around its face. On the head, it often has a darkly colored cap. Weighing between 4-8 kg (9-18 lb), it ranks among the smaller of the gibbons.
North Bornean Gray Gibbon is endemic to the island of Borneo, inhabiting the northern and eastern part of the island.

The Northeast Bornean Orangutan (Pongo pygmaeus morio, german: Borneo-Orang-Utan, french: Orang-outan de Bornéo) is a species of orangutan endemic to the island of Borneo. Together with the Sumatran Orangutan (Pongo abelii, german: Sumatra-Orang-Utan, french: Orang-outan de Sumatra), it belongs to the only genus of great apes native to Asia. Like the other great apes, Orangutans are highly intelligent, displaying advanced tool use and distinct cultural patterns in the wild. Orangutans share approximately 97% of their DNA with humans.
The Northeast Bornean Orangutan is a critically endangered species, with deforestation, palm oil plantations and hunting posing a serious threat to its continued existence.
