The Dugong is not an animal that is very widely discussed. Nonetheless, it is still a remarkable animal, and one that is in great danger of disappearing.

1. Before looking at the e-text, see what you can find out about the dugong in your own language.
2. Then you could take a look at the pages on the dugong at the excellent site of the Great Barrier Reef Marine Park Authority. 
3. The Australian Government also has information on the dugong at its Ministry for the Environment. National Geographic dugong pages are, as you might expect, excellent.
