Palawan Sun Skink

    Leaves, twigs, and barks that have fallen to the ground make up leaf litter, and it's home to a wide variety of plants and animals. Most of the tiny animals found in the leaf litter are invertebrates. They are important food source for toads, skinks, and other small amphibians and reptiles that rely on the shelter and moisture provided by the leaf litter. One of the many creatures living in the leaf litter habitats of Palawan is the Palawan Sun Skink ( Eutropis sahulinghangganan ), a newly described species of skink endemic to Palawan. The name Eutropis sahulinghangganan derives from the Tagalog "sa huling" or "sa huli ng" (meaning in the last), and "hangganan" (meaning frontier). Palawan Sun Skink     The Palawan Sun Skink inhabits thick coastal forests, mangroves, as well as secondary forests and primary forests up in the mountains. I have seen this skink near the peak of Mount Beaufort at elevations of around 1000 masl, but the population of thi...

New Conlephasma Stick Insect discovered in Palawan

Conlephasma sp. photo by Jojo De Peralta
     The genus Conlephasma was born and rose to fame when a unique stick insect discovered at Mount Halcon in the island of Mindoro was distinguished as new to science and allocated a new genus. The genus was named after Oskar Conle, an entomologist who discovered the unique stick insect known today as Conlephasma enigma. It is a species of colorful wingless phasmid believed to be ground dwelling and has the ability to release a potent defensive spray from glands located behind its head to deter predators. This unique phasmid species was officially described by Marco Gottardo and Philipp Heller in 2012.

     Many were awed when this unusual finding was released to the public. Many new species of insects from remote locations are described every year, but it’s an unusual case when a genus and a single species was described at the same time. It has drawn massive public attentions, not just in the Philippines, but also from other countries. Some journalists in the country claimed that the Conlephasma enigma is a spectacular stick insect so unique that it does not have any resemblance to any other stick insects around the world and some biologists affirmed that the C. enigma is the only existing stick insect of its kind in the country. Well, Palawan proved them wrong. A new phasmid was found on one of the highest mountain peak in Palawan. Another spectacular, colorful, wingless stick insect. A new phasmid species belonging to the genus Conlephasma.

     This species was found in the mossy forest on a hike with two American biologists I was guiding. I have seen enough stick insects in more than 19 years of mountaineering, but this odd creature creeping on a mossy branch was unlike anything I have seen. The dark greenish-blue thorax and abdomen are banded with yellow and red. The femur and tibia are also dark greenish-blue in color, but the tarsus is dark-red. Its head is the same color as the body, but the eyes and the antennae which are almost two thirds of its body length are dark-red. All wingless stick insects I have seen have spikes, this one though is smooth. All flightless phasmid I know hides from predators during the day and feeds at night. However, this one was found in the open in the middle of a sunny morning, creeping unconcerned on low vegetation growing in the heart of one of Palawan’s most predator-rich mountain ranges.

     None of us on that hike was an expert in phasmids and no one could tell which branch of Phasmatodea this colorful creature belongs to. I was so intrigued that I posted it on Facebook and asked my friends' opinions. Months after that expedition, I met and guided Albert Kang, a known phasmid enthusiast and we talked about it. It was only then that I got a clear idea what kind of stick insect it was. A new undescribed species of the genus Conlephasma.

Conlephasma habitat in Palawan
     Mindoro has one of the country’s top ecosystems. Its amazing biodiversity can hold its place against most diverse islands in the Philippines and the discovery of a new genus proved it. Mindoro has also unique flora and fauna, but I believe that Palawan was not dubbed as the country’s last biodiversity frontier for nothing. It may be that the next discovery of the year is just lurking there somewhere between our rolling foothills and the cloud-covered mountain peaks. It is hiding and blending among the vast jungle of greens as it has been from generations and generations that passed; waiting to be found, waiting to be discovered.

Palawan Spitting Cobra

      The Palawan Spitting Cobra (Naja sumatrana miolepis) is a spitting cobra that can be found in Palawan. This species is a medium sized, ground dwelling venomous snake. The scales are smooth and unlike some of the most beautiful cobras in Asia, this species has no impressive hood marks. The head is elliptical and depressed, the eyes are medium in size with round pupils, the snout is rounded and the nostrils are large. Juveniles tend to be of different colour than the adult. They can grow up to around 1.5 meters, but spitting cobras over a meter in length are seldom seen and photographed in Palawan . Palawan Spitting Cobra hood mark       It can be seen resting during the day under heavy thickets of grass, stacks of woods and cavities under rocks or soil. Abandoned mice dens are favorite hideouts in grasslands, farms and rice fields. Although it usually hunts for food at night, this species can be seen moving around on the forest floor at sporadic t...

Two-lined Coral Snake

     The Two-lined Coral Snake ( Calliophis bilineatus ) is a small, brightly colored venomous snake of the family Elapidae. It is endemic to Palawan and several of its smaller islands adjacent to mainland. This snake occurs on a wide range of elevation from second growth forest in sea level to mossy forests high up in the mountains where it is largely active during the day. I have been doing night spotting and photography for many years, but I have not seen one during nighttime. This snake spend most of its time burrowed underground, under stacks of woods and leaf piles or cavities under rocks. It has a unique defense behavior compared to other venomous snakes in Palawan. It usually flees when threatened, but when cornered, it will flip on its back and play dead. Other technique to fool attackers is by hiding its head while raising and flicking its red tails. The predator usually finds the colorful moving tail an irresistible target and would go for it, le...

Nepenthes philippinensis

     A Pitcher plant is a carnivorous plant which have a modified prey-trapping leaves that features a deep cavity filled with digestive liquid. There are several endemic tropical pitcher plants growing in Palawan, the most common is the Nepenthes philippinensis .        This species has long, scrambling vines and are often climbers, accessing the canopy of their habitats using tendrils that stretches out and twines around any suitable support. It produces more pitchers and flowers on a single plant compared to all known species of nepenthes in Palawan. There are several color variants, but the lower pitchers are usually reddish and the upper pitchers or traps are green or yellowish.        This lowland species is widespread in Palawan and can be found thriving in soils with low nutrient availability and high concentrations of heavy metals like nickel and chromium. Like all carnivorous plants, this pitcher plant can...

Schultz’s Pit Viper - A spectacular venomous snake endemic to Palawan

     I have heard it said that Palawan has more snakes in the wild than anywhere else in the country. Maybe true, but there are species of snakes commonly seen in other places that are scarce in Palawan rainforest. We have enough vipers in the wild though.  Trimeresurus schultzei Griffin 1909 commonly known as the Schultz’s Pit Viper is one of the most spectacular snakes that can be found here. This snake is endemic to Palawan and its surrounding small islands. Schultz’s Pit Viper       The Schultz’s Pit Viper is primarily arboreal species. They’re capable, but rarely navigate and hunt on the ground. They’re slow and less camouflaged on the ground and therefore more vulnerable on the forest floor. Using its prehensile tail to hold onto branches , it prefers to perch on trees where its green color acts as camouflage while waiting for prey. It is an ambush hunting snake relying on its camouflage to catch food. The heat-sensing lorea...

Palawan Water Monitor

      The Palawan Water Monitor, Varanus palawanensis Koch, Gaulke & Böhme 2010, is a species of monitor lizard commonly found in Palawan. This species is semi-aquatic and inhabits a variety of natural habitats from coastal forest, mangroves, rural areas as well as secondary and primary forests. It is commonly found in the lowland, but also present at elevations above 1000 masl although rarely seen. The Palawan Water Monitor population is more copious in the mangroves, wetlands and riparian forest compared to old-growth forest habitats in the mountains. Palawan Water Monitor     This water monitor is carnivorous and not known to feed on fruits in the wild. It is one of the most efficient predators in Palawan and is intelligent and skillful hunter in both land and water. The dark color blends well on the forest floor and it helps when stalking for preys. It is known to use its tail to stun preys, but the water monitor’s p...

Palawan Mangrove Snake

    The Boiga dendrophila multicincta (Boulenger, 1896) is a large colubrid snake endemic to Palawan. It prefers humid habitats and always seen in woody areas close to bodies of water. This snake primarily occurs in lowland forests, mostly mangrove and riverine habitats, but is also found near mountain streams in the foothills up to old growth forest above 1000 masl. It is commonly seen resting on tree branches overhanging on bodies of water during the day and on the ground hunting for food at night. With its long body, this snake can move swiftly on trees and is also an adept swimmer. It is known to prey on birds and other small arboreal animals, but it seems to spend more time hunting on the ground where food is abundant. Palawan Mangrove Snake     The Palawan Mangrove Snake, also called Palawan Yellow-ringed Cat Snake is mildly venomous. But despite being considered not life-threatening to humans, locals fear this snake for its unpredictable and i...
