Roadkill Green Iguana (Iguana iguana) at Upper Thomson

Location, date and time: Singapore Island, Old Upper Thomson Road; 8 January 2017; 1700 hrs.

Observation: A carcass of a Green Iguana was found on the road. It may have been run over by a vehicle. Its snout-vent length was approximately 20 cm. The total length was 35 cm, but the tail was incomplete, possibly due to a prior injury.

Remarks: Green Iguanas are not native to Singapore. Adult and juvenile individuals, very likely abandoned pets and their progeny, have been recorded in the western and northern parts of Singapore, including Bukit Batok (Tay, 2015), Jurong (Low et al., 2016), Sungei Buloh Wetland Reserve (Chua, 2007) and Kranji Reservoir around Sungei Tengah (Ng & Lim, 2014; Khoo, 2016). This appears to be the first published record in the central part of the island, at the edge of the Central Catchment Nature Reserve.
