SINGAPORE - If you can't get enough of adorable otters, a new YouTube video to commemorate National Day has provided a further glimpse into Singapore's wild otter population in their natural element.

Produced by otter watcher Jeffery Teo, 45, the five-minute clip combines footage taken by fellow enthusiasts over the past year.

The video opens with Bishan's now-famous otter family - fondly named the Bishan 10 - swimming and gambolling about at Bishan-Ang Mo Kio Park.

It also captures other less well-known otter families, which reside in Tanah Merah, Serangoon and Pulau Ubin.

The otter population in Singapore is estimated to number about 50.

Earlier this week, The Straits Times' readers voted in a poll for Bishan's otter family as the 51st object that best represents Singapore in her 51st year.

Said Mr Teo, a senior director in the financial services sector: "I couldn't be more delighted that the Bishan 10 has received so much recognition ever since they appeared on the public's radar last year.

"It shows Singaporeans have truly learnt to embrace the wildlife living our midst, and to appreciate nature more. "

Mr Teo, who spent three weekends putting together the video, added that he hopes it can educate the public on the other otter families which call Singapore home.
