From the thread "
Why no platypus in zoos outside Australia?" thread,
Tatsuslava said about manatees and dugongs. So I create I thread for that.
First,how to distinguish manatee between dugongs?
From my knowledge,
Manatees have a large, horizontal, paddle-shaped tail with only one lobe, which moves up and down when the animal swims.
Dugongs have tail flukes with pointed projections, like a whale with a slightly concave trailing edge.(yes,I copy that)
Second, how well are manatee and dugongs kept in captivity?
Most of the manatees) you have seen is probably the West Indian species. this including all zoo/aquarium in Europe, and possibly all in the US.
Amazonian manatee,as far as I know, are only kept in one aquarium except in south america(where there is a few holders?)And that aquarium is atagawa tropical & alligator garden in Japan.
West african manatee is hold in some Chinese aquarium, as well as toba aquarium in japan.Some holder in china are Chimelong and yantai.
Dugong is held in three aquarium,as far as I know.I believe that toba have one, jakarta have one, and sydney have two.(Get information from wikipedia, I don't know if it's still update)
At last, for
Tatsuslava ,manatee is called 海牛 in chinese and dugong is called 儒艮.(i believe is produced geng1)
