FREE Guided Walk @ Treetop Walk

In an effort to promote an awareness of Singapore’s natural and historical heritage, and to promote conversations amongst Singaporeans, the HSS has begun the Herp Walk! We want to raise awareness, in particular, about Herps! These misunderstood creatures are often thought of as scary or unnecessary. But we want to show Singaporeans that Herps are important and integral to the Singaporean ecosystem! So join us for this walk.

This walk will take place on Sunday, 18 December 2016, 8.00AM-12.00PM

Come down for a leisurely stroll along Treetop Walk. Let the guides regale you with tales about the natural history and transformation of the entire area. Learn about this green space in your very own backyard! If you’re lucky, you might get to see some of our scaly friends! So don’t wait! Register at this link

Of Vipers and Vivipary

Having had to cut short the previous walk in August due to rain, we were delighted to have clear weather for our latest walk in September, once again at the MacRitchie Treetop Walk! We also welcomed two members of the Little Green Men, Sarah and Frances, to join us on our walk; if you’re interested in making a difference for the environment however you can, try contacting them!

img_3525Even before all our participants had arrived, our dedicated spotter Wei Yang found the first herp of the day: a beautiful Oriental Whip Snake (Ahaetulla prasina)! One of the most commonly sighted snakes in Singapore, it ranges widely into parks and gardens to feed on small lizards like geckoes and skinks. With their brilliant green colour and sinuous bodies, they can be easily mistaken for vines or climbing plant tendrils. Mildly venomous, this snake is harmless to humans though it can bite when provoked. As Sankar explained, they are viviparous, meaning they give birth to live young! The word “viper” in fact is derived from “vivipary”, as vipers are amongst the snakes that have this trait.

Say cheese!

As we trekked deeper into the forest,  several Many-lined Sun Skinks were seen basking in patches of sunlight that managed to penetrate to the understory. We also found many weird and wonderful arthropods, such as the caterpillar above! The fact that it was bristling with spines that may also contain venom would have been difficult to swallow for many a bird. img_3541

We were fortunate to have Sean Yap, a member of the Entomological Network of Singapore (ENSING) as well as HSS, to help us identify these strange critters found swarming about on a wooden railing. Apparently these are barklice (Order Psocoptera); harmless insects that feed on algae, fungi, and dead plant tissue that grow on trees, they help keep them clean of detritus!

img_3543We also stumbled across this cool-looking Flat-backed Millipede (Platyrhacus lineatus) with plates whose edges jutted out from the main body. This makes it difficult for predators to attack its more vulnerable underbelly.

pill-cockroachHerps aren’t the only animals that struggle with an image issue. Cockroaches are often hated for being pests that feed on our trash and spread disease. But our native cockroaches play an important role in the forest by feeding on dead organic matter and speeding up the recycling of nutrients! And some of them can be pretty adorable too, like the Pill Cockroach (Perisphaerus sp.) shown above! Who knew that cute cockroaches were a thing!

img_3552Having already trained their eyes with those small little invertebrates, one sharp-eyed participant spotted this Red-crowned Barbet (Psilopogon rafflesii) on a dead tree trunk! Restricted only to our mature forests, it may have been digging for insects or perhaps building a nest.

img_3561img_3573

At last, more herps! The Black-bearded Flying Dragon (Draco melanopogon) on the left was showing off its patagium, the flap of skin that allows it to glide between trees! If you look closely, you can see the rib bones that the lizard swings outwards to open up its wingsuit! This individual may have been displaying to another flying dragon to warn it to keep to away from its territory.

The lizard on the right is the elusive Yellow Striped Tree Skink (Lipinia vittigera), courtesy of our veteran elf-eyed spotter, Ing Sind. Small and nimble, it usually hides amongst the roots of epiphytes (plants that grow on other plants, usually trees, such as orchids) or in tree crevices, emerging to feed on small insects. Like many lizards, it is able to drop off its tail when threatened, and this one was in the midst of regenerating it. The tails of lizards often contain important stores of fat and contribute to maintaining its balance, so losing it, while not life-threatening, can be a major blow; so leave lizards alone, lest they inadvertently lose their head and lose their tail!

img_3577

While on the Treetop Walk itself, we spotted another species of gliding lizard, the Sumatran Flying Dragon (Draco sumatranus)! This one, probably a male, was flashing its yellow dewlap to warn off other males and perhaps show off to nearby females.

Viper Number 1

We were lucky to meet not one, put two vipers on this walk! Both were male or possibly juvenile Wagler’s Pit Vipers (Tropidolaemus wagleri), coiled around young tree seedlings along the trail. These are ambush predators, lying in wait for prey such as small mammals and birds to wander past before striking with lightning fast speed and their forward-swinging fangs. With heat-sensitive pits on their snouts and blood-destroying haemotoxin, these are formidable foes to their enemies, and should always be treated with caution. As the vipers were located extremely close to the trail, well within striking distance of unwary hikers, we gently lifted them deeper into the undergrowth with a long stick; this was for their own safety as well as the safety of others.

Viper Number 2

img_3113On the way back to the Ranger Station, we came across this blooming Tiger Orchid (Gramatophyllum speciosum)! The largest orchid in the world, it went extinct in the wild in Singapore over a century ago before being reintroduced by NParks in various parts of the island. Each individual plant only blooms every few years, with a massive stalk of up to 80 sweet-smelling flowers. We were fortunate to have come across this specimen while it was flowering.

©Herpetological Society of SingaporeNo Herp Walk is complete without a sighting of at least one monitor lizard, and true enough we found this large Clouded Monitor (Varanus nebulosus) basking in the sun! Unlike their bigger cousins the Malayan Water Monitors, Clouded Monitors are restricted to forests and feed mainly on insects and other arthropods they find by digging amongst leaf litter. The widespread presence of these lizards are a testament to how herps can coexist and thrive peacefully in our city. In fact, just the night before our walk, one of its cousins gained international fame by sprinting across the F1 race track during the qualifying rounds! And although that Water Monitor avoided being turned into a pancake, roadkills of these magnificent creatures are sadly all too common. If you’re a driver, slow down, especially near vegetated areas; it saves lives, both human and herp alike!

As we always like to say, don’t Beware of Snakes (and herps); be Aware of them! Spread what you’ve learned to your family and friends too, so that we can continue sharing this little green dot with our herpy friends for generations to come!

We got rained out of our last walk, but we’re back! After an invigorating Festival of Biodiversity, we’re eager to share even more about our native herps and why they should be conserved! This time, we’re teaming up with Little Green Men, a group dedicated to making the world a more eco-friendly place!

Happy World Snake Day!

Snakes: among the most misunderstood, yet revered creatures in the world. Over 3000 species are known to mankind, and they are distributed across every continent except Antarctica. For thousands of years, these legless reptiles have inspired fear and struck awe into the hearts of humans. Even today, many people who encounter snakes react in fear and kill it on sight. Some distasteful sayings, like “The only good snake is a dead snake,” have arisen from the very same fear. To combat this fear, World Snake Day is commemorated on 16th July every year, when conservationists and herp lovers reach out and educate people on the ecological importance and beauty of these strange creatures!

CULTURAL DEPICTIONS OF SNAKES
In the words of the great Edward O. Wilson, “The mind is primed to react emotionally to the sight of snakes, not just to fear them but to be aroused and absorbed in their details, to weave stories about them”[1] It’s no surprise, therefore, that they are such important parts of so many cultures.

Snakes are prominently featured in Hindu mythology, with Nagas appearing in many works of art, representing rebirth, and freedom. Lord Vishnu is often portrayed reclining on a many-headed cobra. Similarly, in Buddhist artwork, Lord Buddha is commonly shown meditating below a large cobra, with its coils forming his seat, and its hood forming an ‘umbrella’.

In Abrahamic cultures, the story of Aaron’s staff turning into a serpent before the Pharoah of Egypt is well known. Asclepius, the Ancient Greek god of medicine learned the secret of bringing people back from the dead from a snake (which were revered as symbols of wisdom and resurrection). Even today, Asclepius’ staff, with a serpent entwining it, has been adopted by hospitals and medical services around the world as a symbol of healing.

SNAKES OF SINGAPORE
You might not think that urban and developed Singapore plays home to snakes, but there are surprisingly  many species that thrive in the various ecosystems that can still be found in our green spaces.

At least 64 species of terrestrial snakes have recently been recorded in Singapore. New records for the island have been made very recently. The Blackwater Mud Snake (Phytolopsis punctata) was only found to be in Singapore in 2014[2], while the second record of the Smooth Slug Snake (Asthenodipsas laevis) was also made in the same year[3].

Roughly 18 species of Sea Snakes may also be found in Singaporean waters. While they are not common sights, they may occasionally be seen by lucky divers. Sometimes, they can even be seen at low tide. Becky Lee from the HSS wrote about her encounter last August with an injured Marbled Sea Snake (Aipsyurus eidouxii) during a walk with the Naked Hermit Crabs.

Singapore plays home to many notable species of snakes, including the Reticulated Python (Malayopython reticulatus). This is the largest species of snake in the world! While they do not reach especially gargantuan sizes in Singapore, they are very commonly seen even in urban habitats! Sometimes, these human encounters result in the snake getting killed out of fear. Although they may seem scary, the pythons want nothing to do with humans, and actually help to keep rat populations at bay!

Despite their unique evolutionary stories and massive ecological importance, these creatures are often victims of negative portrayals, superstitions and prejudice! It only seems fair that we should celebrate their existence and spread awareness on this sssspecial day!
