A rare sighting of the blue-necked keelback snake (Rhabdophis subminiatus) at MacRitchie Reservoir on Saturday, August 1, 2026, has generated excitement among nature enthusiasts in Singapore. The snake, which is both venomous and poisonous, was observed in the reservoir area, and authorities have advised the public to maintain a safe distance.
The blue-necked keelback is known for its distinctive blue or greenish-blue neck and is rear-fanged, meaning its venom is delivered through specialized teeth at the back of its mouth. While its venom can cause severe symptoms in humans, bites are rare as the snake is generally non-aggressive.
According to local wildlife experts, this species is not commonly seen in Singapore, making the sighting particularly noteworthy. The snake's presence at MacRitchie, a popular nature reserve, highlights the biodiversity of the area. The National Parks Board (NParks) has been notified and is monitoring the situation.
Members of the public are reminded to keep a safe distance from any wildlife and to report sightings to NParks. The snake is protected under Singapore law, and harming it is an offense.
