The picture below and the right side are two pictures that released by Soptikx Viki and contained copyrights. The picture below is a picture of coucang that found and bought by Soptikx Viki from one of wildlife black markets in North Sumatra to be freed in the jungle.

The picture below is a picture of female coucang with her baby placed in a box. Viki is working in one NGO (Green Life Project) to protect the wildlife animals and jungle. This female coucang with her baby believed caught for sale by a Chinese business man in Kuala, Langkat regency, North Sumatra, Indonesia.

Many Chinese people in Indonesia believe coucang's heads have a spiritual magic to bring luckiness in business. This brought me a deep sad after knowing the story Viki told me about this poor coucangs but thanks God, Viki was there and has bought and freed them.

The picture on the right side is a picture of female coucang with her baby that have been freed by Viki. There is an amazing moment in the picture on the right side that managed to be captured by Viki's camera. It's a moment when a mum kissed her baby after being freed, this is awesome. This primates were celebrating their release. "Kita bebas anakku", Viki said in Bahasa Indonesia to show his glad expression to me.


There are 3 species of coucang that living in Indonesia, they are living in 3 big Islands of Indonesia i.e Sumatra (Sunda), Java and Kalimantan (Borneo).

Javan Slow Loris (Kingdom: Animalia, Phylum: Chordata, Class: Mammalia, Order: Primates, Family: Lorisidae, Genus: Nycticebus, Species: Nycticebus Javanicus).

Bornean Slow Loris (Kingdom: Animalia, Phylum: Chordata, Class: Mammalia, Order: Primates, Family: Lorisidae, Genus: Nycticebus, Species: Nycticebus Menagensis).

Sunda Slow Loris (Kingdom: Animalia, Phylum: Chordata, Class: Mammalia, Order: Primates, Family: Lorisidae, Genus: Nycticebus, Species: Nycticebus Coucang).

Sunda slow loris (Nycticebus Coucang) is an arboreal primate (living in trees), not on the ground. Sunda slow loris or known well to be called "kukang" by Indonesian people, is a nocturnal animal that start their activities during night till the dawn. While during the day, this omnivore spend time with sleeping and their bites can cause serious allergies due to its toxin.


Sunda slow loris is the only primate that has toxin. Their toxin often used to survive in the wild from the predator attacks or defending the territories. The toxins are not produced from the mouth or teeth. Sunda slow loris produce toxin from the brachial gland, a gland that come from inside of the elbow. The toxin is obtained by licking a gland on their arm before biting.


Coucang bites can cause anaphylactic shock to human, which is a serious allergy symptoms such as red skin, itching, spotting, hot, sore throat, shock, muscle spasms, causing the low blood pressure, and trouble for heart, kidney and respiratory.


In addition to the harmful toxins, coucang bites can also transmit diseases such as rabies or other pathogenic bacteria, so never ever to make coucang as a pet, because they are the wildlife that designed to survive with venomous bite.

Python Reticulatus

Besides freeing coucang into the wild, Viki who is working in Green Life Project is also doing his best to find or buy another animals from wildlife black market to be freed into the wild. The picture above is a snake (Python Reticulatus) that found in a house of local people in Bohorok regency, Langkat district, North Sumatra (9 km before Bukit Lawang).

"I appreciate so much for what Green Life Project has done, I really love to see how they protect the animals and nature. I will always ready to support their great job" Bobi Handoko.
