The oldest manatee in captivity is Snooty (b. 21 July 1948), aged 66 years 38 days as of 28 August 2014. Snooty lives at the South Florida Museum in Bradenton, Florida, USA.
Snooty was brought to the South Florida Museum as a calf in 1949.
He lives in a 60,000-US-gal (230,000-litre) pool with two other manatees.
Snooty’s longevity owes much to the fact that he lives in a controlled environment. In the wild, factors such as algal blooms, boat strikes and fishing debris see most manatees die before they reach the age of 10.
