They live in Northern Australia, Shark Bay, Southern Florida, Morton Bay, and Indian and Pacific Oceans. There are many reasons the dugong is endangered. The dugongs have been long hunted for its meats, blubber, oil, and hide. World's population for dugongs is believed to be reduced to less than 40,000. The dugong is classified under endangered, and the dugongs get chopped up by the boat propellers when they swim by a boat.
Some solutions are by having no boating areas and have no hunting for the dugong in some countries.
I studied the dugong to find out what it was and why it was endangered. If the dugong became extinct I think the ecosystem for underwater would have one less plant eater and that leads to boats getting stuck in the sea grasses. That is why I studied the dugong.
