There is no information available regarding the average lifespan of Cephalorhynchus heavisidii in captivity or in the wild. The average lifespan of most wild delphinids ranges from 17 to 25 years, with a few living into their early 50s. Although similar averages are found for captive dolphins, few captive individuals live past their 20s. In general, delphinids are vulnerable to bacterial, fungal, and viral infections and have been found to suffer from heart and respiratory disease, stomach ulcers, and even cancer. Dolphins are also vulnerable to a number of different parasites including flukes, tapeworms, and roundworm.
