dugong channel

In the past there were a lot of dugongs in the lagoon. They grazed on the shallow seagrass fields near the shore. With their constant movements and grazing, the dugongs made a deep channel through the seagrass. People used this ‘dugong channel’ to paddle to the mangroves. But when people killed the dugongs for their meat, the channel filled up with mud. Nowadays, people have difficulties to reach the mangroves during low tide.
