Biologists believe this 4-foot-long, 40-pound Australian lungfish is about 90 years old. It was brought to a San Francisco museum from Australia in 1938.
“By default, Methuselah is the oldest,” said Allan Jan, senior biologist at the Academy and the fish’s keeper. Methuselah’s caretakers believe the fish is female, although it’s difficult to determine the species’ sex without a risky blood draw. The Academy plans to send a tiny sample of her fin to researchers in Australia, who will try to confirm the sex and figure out the fish’s exact age.
“She’s a little picky and only likes figs when they are fresh and in season. She won’t eat them when they’re frozen,” said Jeanette Peach, spokeswoman for the California Academy of Sciences. The Academy has two other Australian lungfish that are younger, both believed to be in their 40s or 50s, Jan said.
The Australian lungfish is now a threatened species and can no longer be exported from Australian waters so biologists at the Academy say it’s unlikely they’ll get a replacement once Methuselah passes away.AP NEWS
