Otters have been sighted at various locations on Pulau Ubin!
From the Ubin Volunteers blog...
"Actually for the last few weeks, a few Ubin NParks officers volunteers, security guards and even visitors have spotted the Otters at Chek Jawa, Jelutong and now even Jln Ubin. The security guards at Chek Jawa reported seeing the otters swim near to the floating pontoon on quiet days during high tides."
