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

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.

Banded Keel-throated Pitviper

    The Banded Keel-throated Pitviper Tropidolaemus subannulatus (Gray, 1842) is said to be the most common pit viper in the Philippines. This venomous pit viper species is also native to Indonesia, Malaysia, and Brunei. Like the Schultz’s Pit Viper , this species is primarily arboreal and an ambush-hunting venomous snake. It is active at night, but also seen moving around during the day, especially in the rainy season.

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 loreal pits are used to locate warm-bl

New Opadometa spider discovered in Palawan

      One of the most unique and beautiful spider in Palawan is the rare metallic blue spider of the genus Opadometa . Opadometa is a genus of spiders in the family Tetragnathidae and is separated from other Leucauge spiders by its pear-shaped abdomen and its distinctive fourth pair of legs. In addition to the rows of curved hairs, this leg also has a thick brush of spines. Palawan is rich in Araneae, but this is the only large blue spider seen in Palawan.       We did some research and found out that this blue spider is a species that has not yet been described . This blue spider is not among the four documented Opadometa species and the described eight subspecies. The closest spider I found on the internet is the newly discovered Opadometa sarawakensis , another unique spider found in Malaysia.        We found the webs during the day with the spider mostly at the hub and sometimes at the web margin. The web is large, usually over a meter in diameter and placed horizonta

Palawan Stink Badger - A mephitid endemic to Palawan

      Let me introduce you to our endemic Mydaus marchei (Huet, 1887), the Palawan Stink Badger. The Palawan Stink Badger was once thought to be more related to badgers than with skunks because of its appearance that closely resemble badgers. It was recently re-classified as one of the Mephitidae ,  a family of mammals comprising the skunks and stink badgers . Like all mephitids, this guy possess a specialized anal glands that can spray a powerful noxious chemical. The M. marchei rely almost entirely on this powerful odour for their defense. A foraging Palawan Stink Badger.      I still can remember a night on the western coast when a dog attacked a foraging stink badger not fifteen meters from where we were sleeping. It was a very annoying experience. I had a hard time finding my tent zippers, but I was out in time to see the last of my hiking companions running off, leaving trails of vomits on the ground. Relocating the camp in the middle of the night was never fun and e

Philippine Palm Civet - A disappearing Viverrid in Palawan lowlands

     Paradoxurus philippinensis (Jourdan, 1837) or the Philippine Palm Civet is getting scarce in Palawan. It used to be abundant in primary and second-growth forest, but conversion of its natural habitat to farmland pushed them deeper in the mountains. These wild animals are nocturnal in habit, solitary in nature and mainly arboreal. They are omnivorous, but usually favored fruits. The Philippine Palm Civets sometimes feed on birds and small rodents and w hen its natural wild food get scarce, it also visits the immediate vicinity of farmhouses and prey on chickens.       Most farmers here misunderstood these animals, considered them a threat to poultry and were often trapped or shot in sight. This kind of civet always prefer fruits if it's available. I used to breed fighting cocks at my father's farm and I've observed this civet feeding habit several times in the past. Different kinds of fruit bearing trees were abundant in the farm, civet always goes f

Palawan Horned Frog - A cryptic frog endemic to Palawan

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, leaving the true

Nepenthes philippinensis
