Observations

As in other whales, these animals attain sexual maturity before they are fully grown. It is estimated that they attain physical maturity in about 25-30 years. Although there are no detailed studies, some estimates suggest these animals may live over 100 years in the wild with one study estimating that some individuals may live up to 114 years [0434].
