Portia the sea lion celebrates turning 28
TURNING 28 may not seem like the biggest achievement.
But for Portia the Australian sea lion, it is an age few would have guessed she would make.
Mooloolaba's Sea Life Sunshine Coast mammals manager Mark Ryan said the birthday made her quite extraordinary.
"She's lived well past the usual age of Australian sea lions," he said.
"They will generally live to late teens-early 20s if they're lucky, so 28 is a real milestone for an Australian sea lion.
"She is the oldest living Australian sea lion that we know of anywhere in the world."
Portia arrived on the Coast when she was two and Mr Ryan said she might have received some advice on how to live a long life from her first friend at the park.
"When she came over from Adelaide, she was here with the oldest Australian sea lion ever recorded, which was Macy, who was her best friend and she lived to be 31 years of age," he said.
While Portia is getting older, Mr Ryan said she had not started to show signs of slowing down.
She's still very active and, as people would have seen at her party, she's very playful as well," he said.
