A bottle-nose dolphin's average life span is 20 years or less.
The age is estimated by examining a sliced section of a tooth and counting the layers.
The oldest dolphin recorded is Nellie from Marineland, Florida. She has reached her 56th birthday as of February 2009. Animals in captivity get better healthcare and therefore live longer.
