A lesser-known family of otters are currently living in the west of Singapore.

They are residing in the area near Pandan Reservoir and are known as the "Pandan family".

While they are not as prominent as the Bishan or Marina families, they are no strangers to the frequent park connector (PCN) users there.

PCN users waited patiently for otters at Pandan Reservoir

Seven otters from the Pandan family were spotted doing their usual boogie-woogie in the middle of the PCN pavement on Saturday.

The seven of them were clearly having a whale of their time rolling about and rubbing against the sandy pavement, unbothered by the people who were running past the area

As a result, a few park users had their way blocked by these critters.

But they have no qualms about waiting at all.

The park users simply kept a safe distance from the otters and watched on until they were done with rolling and cleared the path.

The waiting time was about five to 10 minutes.

Why do otters roll on the grass or in the sand?

Otters rolling on the grass, sand or soil can be quite amusing to watch, but they have a reason doing so.

And that is to dry themselves and to realign their fur so that it can better trap air when they swim.

Things to observe when you encounter otters

Keeping a safe distance from the otters is important when you encounter them.

Besides keeping a safe distance, one should refrain from talking loudly or using flash photography as that might scare or provoke them.

Like all wild animals, otters might turn aggressive when they feel threatened.

Do not feed otters as that might alter their behaviour. Otters can find their own food in the environment and that helps to keep the ecosystem healthy.

If you are walking your dog, it is important to keep your dog on a tight leash in areas where otters are spotted.
