Even-toed Ungulates

Order Artiodactyla


This order contains the even-toed ungulates, i.e. herbivores with two or four toes.

In Singapore, there are 4 species - 1 pig and 3 deer.

Wild Pig (Sus scrofa)

When Singapore was developed, the Wild Pig population was decimated, even on Pulau Ubin. Recently, there has been an increase in population, likely from Johor, so much so that this species is now listed as common[1]. Being a prolific breeder and without natural predators, it is likely to come into conflict with human. It can be found at Pulau Ubin, Pulau Tekong, Western Catchment, Central Catchment, Seletar and Changi, as well as the neighbouring wooded areas.

Sambar (Cervus unicolor)

The Sambar Deer or Sambar was a deer native to Singapore. It was last sighted in the Bukit Timah area in the 1920s[2]. In the 2000s, they were reintroduced into the Central Catchment area. There are now reportedly 20 of these deer in the wild[3]. This fact came to light when a sambar was knocked down by a car on SLE on 3 Mar 2010.

The other extinct deer in Singapore is the Indian Muntjac (Muntiacus muntjak).

Lesser Mousedeer (Tragulus kancil)

The Lesser Mousedeer is the smallest of the mousedeer. They can still be found at Bukit Timah and Central Catchment.

There has been some controversy regarding the identity of the following mousedeer at Lower Peirce[4].

Greater Mousedeer (Tragulus napu)

The Greater Mousedeer is larger than the Lesser Mousedeer. It was thought to be extinct in Singapore until it was rediscovered on Pulau Ubin in 2009[5]. It has also been reintroduced into the Central Catchment. It can be distinguished from the Lesser Mousedeer by the five white stripes on the chest (compared to three on the Lesser Mousedeer).

  1. Might come as surprising but I had an incredibly fortunate experience to witness a group of these sambar deer just 3 to 4 weeks ago. Having gone out for a midnight cycle on my electric bike, I was returning to Ang Mo Kio from Sungei Kadut at or about 2.40 am. I passed by a family of wild boar shuttling through the underbrush along the Mandai Park Connector and spotted a couple of fishermen by the reservoir. Up ahead, I saw huge creatures, which resembled a deer species of some sort. I directed my bike's headlamp towards the group of 4 or 5 animals and I was pleasantly shocked. These were huge deer, creatures I had the failure test inkling of existing in the rapidly decreasing wild landscape of our country. I saw at least 3 doe and one large male with a set of magnificent antlers on him.

    It was miraculous, to say the least, considering just how rare the population of wild sambar deer is in Singapore.

    It was a sight I will not soon forget.

  2. Amazing story!

    I, also, was very fortunate to cross-paths with the majestic Sambar deer. Last night as i rounded a bend on old upper thomson road, there in front of me stood a massive antlered male.

    It trotted off into the bush quickly.

    Amazing to see!
