There are currently about 65 species of mammals in Singapore. 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.
Many surviving species have critically low population numbers, the most seriously endangered being the cream-coloured giant squirrel, last sighted in 1995 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, and the greater mouse-deer on Pulau Ubin in 2009.
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 far more common, found in relatively large numbers throughout the main island, and also on the offshore islands of Pulau Ubin and Pulau Tekong. The largest marine mammals are species like the dugong and dolphins.
