Mostly harmless” – that’s how intergalactic traveller Ford Prefect describes Earth, after 15 years of research, in The Hitchhikers’ Guide to the Galaxy. What his entry neglects to mention, however, is that its dominant life forms are anything but. Douglas Adams’ portrayal of the destruction of our planet by invading aliens was originally intended as a joke, but when the author realised the rate at which we are snuffing out the species that share our small blue-green world, he shifted from fiction to fact and spent a year travelling the world in search of the weirdest and most wonderful endangered species on Earth. His adventures, broadcast by the BBC in hit-series Last Chance To See, served as the inspiration for this series, our very own nod to the magnificent work of Southeast Asia’s most dedicated conservationists and the often peculiar creatures they are fighting to protect. Enjoy – and spare a moment to consider just how Vogon-like the human race has become.

Tree spirit: colugo

“The colugo is also known as a flying lemur, although it isn’t a lemur and it doesn’t fly,” explains Chris Shepherd, regional director of Traffic. Named because of its nocturnal habit and the shape of its fox-like head, “It does glide, however, and is an amazing animal.” Traditionally believed to be related to bats, colugos are in fact related to primates – and the most aeronautically skilled of all gliding mammals. Their gliding membrane is as large as geometrics will allow, and surrounds almost the entire body, extending from the tips of the fingers and toes to the tail. Even the spaces between the fingers and toes are webbed to increase the total surface area (as in a bat’s wings, hence the confusion), allowing the most determined examples to soar distances of up to 136 metres – the longest ever recorded – in one apparently effortless motion.

Graceful in mid-glide, flying lemurs almost never descend to the ground, where their huge flaps of skin render any attempt to walk upright almost impossible. Instead, they spend their days sleeping in tree hollows or hanging upside-down from branches, clinging spread-eagled to tree trunks and climbing in short hopping bursts. Although boasting the kind of teeth normally associated with carnivores, the colugo’s diet consists of fruit and leaves. “It’s a very specialised feeder, eating parts of leaves with comb-like teeth which they use to ‘scrape’ the layers off.” It isn’t the only specialised feeder in the region: almost 90% of the Philippine Eagle’s diet consists of flying lemur.

“There are two species: one, Cynocephalus volans, endemic to the Philippines; the other, Cynocephalus variegates, here in parts of Southeast Asia. Amazingly, the best place to see them is in Singapore, possibly because there aren’t too many predators left there. Their coloration makes them blend perfectly with the tree bark. Often one does not even notice them until that bump on the tree glides away into the darkness.”

Singular serpent: Mcgregor’s pit viper

“Snakes are renowned for creating a sense of fear and loathing in many people, and as a consequence have become maligned creatures, but there are also those who love them, as a fascinating topic of study, as photogenic subjects for wildlife portraits, or as exotic pets,” says wildlife photographer Jeremy Holden. “One particular snake, perhaps the prettiest in all Southeast Asia, has inspired all of these things. McGregor’s pit viper, Parias mcgregori, is a singularly striking example of serpent-kind. At less than a metre long, it’s a pygmy compared to some of the region’s largest snakes – the king cobra can reach up to 6m and the reticulated python up to 9m – but in this case, small is beautiful. This viper, unlike many of its family, is not cryptically coloured. Whereas many snakes try to blend into their surroundings, especially ambush predators like the vipers, the Mcgregor’s is an immaculate golden yellow or sometimes a ghostly ivory white.

“This unusually beautiful snake has suffered because of its looks. Collectors will pay thousands of dollars for a specimen, and until recently this species seemed destined for extinction in the wild. The problem is that Mcgregor’s pit viper is restricted to Batanes Island in the Philippines, and because of rampant deforestation is now found only on the forested slopes of a single volcano, Mt Iraya.

“It’s a recipe that has caused the extinction of many species in the past: a high monetary value and a very restricted range. But it can also inspire conservation action, and such has been the case with Mcgregor’s pit viper. A captive breeding and release programme may help to save this species from extinction. It will probably never be common, but if its remaining habitat can be protected at least now it may have a future.”

Costumed ape:

red-shanked douc

Glimpsed from afar, the red-shanked douc – Pygathrix nemaeus – looks not unlike a little potbellied man clad in grey shirt, black trousers, maroon leg-warmers and white gloves. Smiling eyes are shaded by powder-blue eyelids and its face is ringed by a long, white ruff. Known as the ‘costumed ape’, this leaf-eating Old World monkey “is one of the most colourful primates in the world”, says Larry Ulibarri, head of Vietnam’s Son Tra Douc Research and Conservation Project, and Frankfurt Zoological Society. “They inhabit a diversity of tropical forests in north and central Vietnam, east-central Laos and the northern most tip of Cambodia, living in small families that are loosely connected within a large social group and regularly come together to sleep.”

Between dozes, doucs move almost silently through the treetops. Adult males lead the troupe from branch to branch, followed by females and infants, with juvenile males bringing up the rear. When spooked, they bark loudly and rush around the trees slapping branches to sound the alarm. Sociable creatures, doucs have been known to dine communally. Their portly bellies are the product of having a large stomach divided into sacs filled with bacteria that digests the cellulose in leaves, which in itself causes another, equally noticeable by-product – conspicuous burping.

The main predator of these peaceful primates is, as always, humans. Native people hunt them for food and body parts, which are used in traditional medicine, and the illegal wildlife trade in doucs continues to thrive due to a lack of effective law enforcement. During the Vietnam War, much of the douc’s habitat was heavily bombed or destroyed with defoliants such as Agent Orange. According to one less than pleasant rumour, soldiers also used them for target practice.

“Images of doucs often grace maps, books and tourism advertisements in Indochina,” says Ulibarri. “Considering their striking colouration, this is not surprising, yet surprisingly little is being done to protect these charismatic monkeys. Decisive measures are needed if the doucs are going to have a chance to survive.”
