Not wanting the animals to continue suffering in that sad state, the divers tried to convince their captor to set them free, informing him that dugongs are a protected species vulnerable to extinction.
"When we left the island, the fisherman agreed to release them," Lim said. "But since we were not so convinced he would, I posted the video to social media." The other divers did as well.
And it's a good thing that they did. Within hours, Lim was contacted by wildlife authorities requesting the location of the cages. The next day, officials descended on the spot and found the animals still trapped.
That's when they were finally set free.
