Wildlife photographer Chang Fu Wen was visiting Woodlands Waterfront Park on the morning of Aug. 2 when he spotted two smooth-coated otters hunting for lunch.

It's meal? A very large catfish.

The sizeable catfish had attempted to escape again and again, Chang told Mothership.

The triumphant otter eventually emerged victorious — Chang captured it clasping the large catfish tightly in its mouth with its otter pal trailing behind.

Catfish, which are infamously coined as 'Ah Seng' within the local angler community, are a common aquatic species along our shores and a staple in otters' diets.

However, it was the sheer size of this particular fish that made the catch even more impressive.

The winner takes it all

In a Facebook post on Nature Society Singapore, Chang shared how the otter holding the fish was reluctant to share its catch.

He remarked, "The [otter] with the fish [was] not really willing to share."

Chang also observed the otter eating the tail of the fish first, likely because the catfish's head was too large.

He noted that otter watcher Bernard Seah shared that the catfish's head "was like [a] helmet".

It was only when the otter had reached the fish's internal organs that it allowed its companion to join in the feast, stated Chang to Mothership.

First dibs, I guess.

One man’s trash is another man’s treasure

It appears that lunch hour wasn't over just yet, for a short while after the otters had abandoned the fish carcass, Chang spotted another creature capitalising on the leftovers.

It was none other than a Malayan water monitor lizard who wanted a piece of the pie.

Although three water monitors appeared, only one picked up on the leftovers while the other two ignored it.
