SINGAPORE - Crocodiles can usually be seen sunbathing and swimming at Sungei Buloh Wetland Reserve, but they have made surprise appearances at other parts of the island.
While they have been classified by the International Union for Conservation of Nature as "regionally extinct" in Singapore in 1996, research has found that crocodiles have never left the Republic's waters.
The species found here is the estuarine crocodile, which has been recorded in local waters since the early 1800s.
Estuarine crocodiles are native to Singapore and feed mostly on fish, said Dr Adrian Loo, group director of wildlife management at the National Parks Board (NParks).
Also known as saltwater crocodiles, they can reach more than 5m in length, according to NParks' website.
The existence of these apex predators occupying the top of the food chain means Singapore has a stable, healthy ecosystem, wrote Ms Kate Pocklington, senior conservator at the Lee Kong Chian Natural History Museum at the National University of Singapore, in her e-book about saltwater crocodiles here.
The Straits Times recaps some sightings of the world's largest reptile in Singapore.
Water and fishing activities had been scaled back after the reptile was seen on Feb 14.
The authorities caught the reptile and released it into the wild as a safety precaution.

A crocodile warning sign that was put up near the National Sailing Centre after a crocodile was spotted at a construction site in East Coast Park in Novembe 2019.
The 400kg creature, believed to be one of the largest wild specimens here, was found dead with a metal rod in its eye and a large fishing hook lodged in its mouth, said PUB.
Its body was said to have been disposed at a nearby farm.
PUB said then that since 1989, it has authorised a team of handlers to capture the reptiles alive and hand them to a farm in Kranji for safekeeping.
The largest crocodile caught in the wild in Singapore was 4.72m long, and was presented to the then Raffles Museum.
It was shot by game hunter George Paddison Owen in September 1887 at the Serangoon riverbank.
While crocodiles were hunted during the colonial era, a person who kills one today can be fined up to $50,000 and imprisoned for not more than two years.
Dr Loo said: "Should members of the public encounter a crocodile, they should stay calm and back away slowly.
"They should not approach, provoke, or feed the animal."
The public may also contact NParks on 1800-471-7300.
