Jordan Doyle and Mary Lister had gone out otter-watching with a wildlife photographer when the animals appeared."I'd had the ring with me for a while and Mary is a huge fan of otters, so I thought to myself, right, this is the time to propose," Mr Doyle, 28, told the TheIndianSubcontinent.

A group of otters then swam over to gatecrash the romantic moment."When I asked them to pose for a photo, the otters came out of the water and approached the couple," photographer Bernard Seah told the TheIndianSubcontinent."I was like, oh my god, I cannot believe this."'Completely special'The otters are part of a group known as the Bishan 10, one of several otter families thriving in Singapore's urban areas.
