Meet Methuselah, the fish that likes to devour contemporary figs, get belly rubs and is thought to be the oldest dwelling aquarium fish within the global.
within the Bible, Methuselah was Noah’s grandfather and was once mentioned to have lived to be 969 years antique. Methuselah the fish isn’t reasonably that historical, however biologists at the California Academy of Sciences believe it is about NINETY years old, with no recognized dwelling peers.
Methuselah is a 1.2-metre-long (4-foot), 18.1-kilogram (40-pound) Australian lungfish that used to be dropped at the San Francisco museum in 1938 from Australia, which would make it greater than 82 years old.
A primitive species with lungs and gills, Australian lungfish are believed to be the evolutionary link among fish and amphibians.
No stranger to publicity, Methuselah’s first appearance within the San Francisco Chronicle used to be in 1947: “Those unknown creatures — with green scales taking a look like recent artichoke leaves — are identified to scientists as a possible ‘missing hyperlink’ among terrestrial and aquatic animals.”

Till a few years ago, the oldest Australian lungfish was on the Shedd Aquarium in Chicago. But that fish, named Granddad, died in 2017 on the age of NINETY FIVE.
“Via default, Methuselah is the oldest,” stated Allan Jan, senior biologist at the Academy and the fish’s keeper.
Age and intercourse to be showed
Methuselah’s caretakers consider the fish is female, even though it’s tricky to figure out the species’ sex without a risky blood draw. The Academy plans to send a tiny pattern of her fin to researchers in Australia, who will attempt to confirm the intercourse and determine the fish’s actual age.
Jan says Methuselah likes getting rubbed on her back and stomach and has a “mellow” persona.
“I tell my volunteers: faux she’s an underwater puppy, very mellow, mild, but of course if she will get spooked she is going to have sudden bouts of energy. But for essentially the most section she’s simply calm,” Jan said.
Methuselah has advanced a style for seasonal figs.
“She’s a little bit choosy and most effective likes figs after they are contemporary 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 other Australian lungfish which are more youthful, both believed to be in their 40s or 50s, Jan said.
The Australian lungfish is now a threatened species and can now not be exported from Australian waters, so biologists at the Academy say it is not going they’re going to get a substitute as soon as Methuselah passes away.
“We simply provide her the most efficient imaginable care we will provide, and confidently she prospers,” Jan stated.
