If you are a diver, you've probably heard of these creatures before. For those of you who aren't familiar with dugongs, they are an endangered marine species that are protected in the waters of Mozambique. Inspirations for the mermaid myth is said to have been taken from dugongs. They are comfortable in waters that are about 10 metres deep but can dive deeper. Dugongs are also known as sea cows and even though there is no resemblance, the marine creature is said to be directly related to elephants. Strange isn't it? Since dugongs are shy creatures, they don't usually approach humans. This doesn't mean that they are antisocial, dugongs do talk amongst themselves through chirps, whistles and barks. They are mostly spotted on the east African coast.
