2.10 Do dolphins live shorter in captivity?
There is no evidence to support that statement.
A recent study, comparing the survival of dolphins in
captivity from 1940 through 1992 showed no significant
difference in ASR between the "captive population" and the
Sarasota Bay population. The ASR for the captive population
was 0.944 (life expectancy: 17.4 years).
Also in captivity dolphins have reached ages over 40 years.
