The matriarchal structure of orca society is well known, with females potentially living up to 90 years and playing a crucial role in passing on knowledge to the younger animals. Previous research into why these females live so long after they stop reproducing – an average of 22 years – has suggested it’s to play an ‘elder’ role in the society, passing on culture, language and more to the youngest pod members.
