There are currently about 65 species of mammals in Singapore. [1] Since the founding years of modern Singapore in 1819, over 90 species have been recorded, including megafauna such as tigers, leopards and sambar deer. Most of these have since become locally extinct largely due to rapid urban development, with occasional large mammals such as Asian elephants swimming across the Straits of Johor from Johor, Malaysia. [2]
Many surviving species have critically low population numbers, the most seriously endangered being the cream-coloured giant squirrel, last sighted in 1995 [3] and now possibly extirpated. The Raffles' banded langur is also down to around 60 individuals. However, some species have been rediscovered in more remote parts of the country, such as the Malayan porcupine which was detected on Pulau Tekong in 2005, [4] and the greater mouse-deer on Pulau Ubin in 2009. [5]
The most commonly seen native mammals are the crab-eating macaque and plantain squirrel. The largest terrestrial mammal is the sambar deer, however, its population still remains extremely small. The wild boar is common on the offshore islands of Pulau Ubin and Pulau Tekong and on the mainland. The largest mammals are marine species like the dugong and dolphins.

Pulau Ubin, also simply known as Ubin, is an island situated in the north east of Singapore, to the west of Pulau Tekong. The granite quarry used to be supported by a few thousand settlers on Pulau Ubin in the 1960s, but only about 40 villagers remained as of 2012. It is one of the last rural areas to be found in Singapore, with an abundance of natural flora and fauna. The island forms part of the Ubin–Khatib Important Bird Area (IBA), identified as such by BirdLife International because it supports significant numbers of visiting and resident birds, some of which are threatened. Today, the island is managed by the National Parks Board, compared to 12 agencies managing different areas of the island previously.
Singapore has about 65 species of mammals, 390 species of birds, 110 species of reptiles, 30 species of amphibians, more than 300 butterfly species, 127 dragonfly species, and over 2,000 recorded species of marine wildlife.
The Raffles' banded langur, also known as the banded leaf monkey or banded surili, is a species of primate in the family Cercopithecidae. It is endemic to Singapore and southern Peninsular Malaysia. The species underwent taxonomic revisions in 2019 and 2020, in which two former subspecies were elevated to separate species. As a result, the Raffles' banded langur meets the criteria for being listed as critically endangered by the IUCN. It is mainly threatened by habitat loss.
Bat Conservation International (BCI) is an international nongovernmental organization working to conserve bats and their habitats through conservation, education, and research efforts.
Johora singaporensis, the Singapore stream crab or Singapore freshwater crab, is a critically endangered species of freshwater crab endemic to Singapore. It grows to a size of 30 millimetres (1.2 in) wide.
Igneous rocks are found in Bukit Timah, Woodlands, and Pulau Ubin island. Granite makes up the bulk of the igneous rock. Gabbro is also found in the area and is found in an area called Little Guilin, named for its resemblance to Guilin in South China. This area is in Bukit Gombak. Sedimentary rocks are found on the western part of Singapore, which is mainly made of sandstone and mudstones. It also includes the southwestern area. Metamorphic rocks are found in the northeastern part of Singapore, and also on Pulau Tekong, off the east coast of Singapore. The rocks are mainly made up of quartzite, and also make up the Sajahat Formation.
