The California Academy of Sciences is excited to reveal the age of beloved Australian lungfish Methuselah (Neoceratodus forsteri), the oldest living fish in an aquarium anywhere in the world. Cutting-edge DNA analysis led by Dr. Ben Mayne of CSIRO and Dr. David T. Roberts of Seqwater estimated Methuselah’s age to be 92 (± 9 years), older than her previously estimated age of 84.
