S.F.'s 90-year-old fish is breaking records

Methuselah the Australian lungfish arrived at the Steinhart Aquarium in 1938, when Willie Mays was six years old and Al Capone was still seeing time in Alcatraz. Cal Academy of Sciences biologist Ryan Schaeffer gives Total SF co-hosts Peter Hartlaub and Heather Knight a tour of the famous fish's enclosure, before talking about the life, care, puppy-like quirks and history of the world's oldest fish in a zoological settling. Produced by Peter Hartlaub. Music from the Sunset Shipwrecks off their album "Community," Castro Theatre organist David Hegarty and cable car bell-ringing by 8-time champion Byron Cobb. Follow Total SF adventures at www.sfchronicle.com/totalsf  Learn more about your ad choices.
