Throughout the Gardens
Singapore is home to three species of monitor lizard, but one stands above the rest — in every sense. The Malayan water monitor (Varanus salvator) is the most common and can reach up to 3 metres in length. Closely related to the Komodo dragon, the largest extant lizard, it is characterised by its long body, powerful limbs, muscular tail, and flickering forked tongue, it is an unmistakable presence in our parks, mangrove swamps, forests, and even the occasional concrete canal.
Its ecological contribution is significant. V. salvator is a carnivore with a remarkably diverse diet — insects, crabs, snakes, and fish all feature on the menu — allowing it to regulate prey populations across multiple species. It is also an important scavenger, consuming carrion and accelerating biomass decomposition and nutrient recycling. Remove it from the ecosystem and you lose a natural pest controller, a waste processor, and a food source for larger predators such as crocodiles. It is, in short, irreplaceable.
Despite their imposing size, monitor lizards are generally shy animals that will not attack humans unless provoked or cornered. The guidance is straightforward: keep a safe distance, do not chase or corner the animal, and it will go about its business undisturbed.
