Irrawaddy Dolphins in Sabah


SANDAKAN: Dolphins are in our rivers. Irrawaddy Dolphins, to be precise. They can be found in the Kinabatangan River in Sandakan, Cowie Bay in Tawau and along the coasts of Sabah, Sarawak and Brunei.

Irrawady Dolphins are facultative river dolphins, meaning they not only swim in coastal areas but also make their way into rivers.

Teoh Shu Woan, a Marine Conservation Masters student at UMS who is currently conducting research on Irrawaddy Dolphins, has identified 28 Irrawaddy Dolphins in Cowie Bay.

“My current estimate through photo-id mark-recapture method is 28 but I need to do some adjustments to get a less bias estimate, but there are definitely more,” said Shu Woan.

According to Shu Woan, when fishermen collect fish from their nets, the Irrawaddy Dolphins would be waiting nearby.

“The fishermen would pick some fish that were caught in the net and throw them to the dolphins,” she said.

Shu Woan said the dolphins would not disturb the fish caught in the net but instead wait for the fish to be thrown to them.

Like most species of dolphins, the Irrawaddy Dolphins are not aggressive. They are intelligent creatures that are also believed to have a mutualistic relationship of co-operative fishing with traditional fishers.

In Kinabatangan, they are viewed as something sacred.

“When they (Kinabatangan community) see the dolphins, they do not disturb them or call them names because they believe that doing so will cause a huge wave,” said Shu Woan.

However, the current fickle weather has forced these creatures to refrain from traveling upstream in the Kinabatangan River.
