- Observations
The dugong may feature some form of continuous tooth development [0002]. It is estimated that these animals live more than 50 years in the wild, with one estimate suggesting that they may live up to 73 years [0434]. Their longevity has not been studied in detail in captivity, but one animal was still alive after 25.3 years [0671].
