The data give the age and the length of dugongs Dugong dugon (Müller) captured near Townsville in north Queensland, Australia. The lifespan of a dugong is 50-60 years.
These data were working estimates. In particular the method of determining the age of dugong has changed somewhat since the data were recorded.
