This carnivorous plant uses a sugary nectar to attract and trap its prey, which include small moths, flies, wasps, and grasshoppers (other animals, such as tadpoles and mosquitoes, use the pitcher as a breeding ground). Monkeys have been seen drinking the water collected in the pitchers after it rains, which has earned them the nickname of "Monkey Cups." A look at the photo above and the plant's ability to blend into the jungle floor sheds additional light on why it is so successful in trapping unsuspecting prey. There are ten species of pitcher plants in Kubah National Park.
Orangutans make their home in the Borneo rainforests, and you can see them living in the tree tops all across the island. If you're on limited time, though, you can visit the Semenggoh Nature and Wildlife Center where they undergo rehabilitation.
Pythons and Black Cobras
Watch your step when you're hiking throughout Borneo, as the jungles are home to two intimidating types of snakes: The python and the black cobra. It is not uncommon for locals to eat the former, and if you're feeling adventurous, you can find it at local markets in and around Kuching.
Rare Palm Trees
The Ekor buaya palm looks somewhat like a crocodile tail as it grows directly upwards at a slight angle. This corrugated leaf is light and tough, and it has traditionally been used as a roof-building material by jungle tribes. What makes it special is that it is only found on Borneo near Kuching, and it grows in one very specific location in Kubah National Park along the Selang Trail.
Head hunting -- the act of ambushing and beheading -- was widely practiced by tribes across Borneo up until the 20th century, and, believe it or not, might still be practiced in some remote areas today (which is why you should always use a guide when exploring the jungles of Borneo). The ritual violence was part of a "growing process" for young men of the tribe, and the heads were usually hung or displayed on sticks to ward off evil spirits. Look for old skulls when visiting traditional longhouses.
