Oz had been with the aquarium since it opened in 2005.


Georgia Aquarium in Atlanta is mourning the death of one of its most beloved residents. Last week the aquarium shared on social media that Oz, its 18-year-old sea otter, was humanely euthanized Thursday afternoon.

After suffering several unexpected seizures Tuesday, Oz was given an MRI that revealed lesions on the brain. According to the aquarium's Twitter account, Oz didn't recover or regain mobility.

"This sudden loss is devastating," the aquarium wrote on Twitter. "Oz has been a part of our family since we opened in 2005 and came to us from Oregon Zoo. He was our senior sea otter who was a companion and leader to the other sea otters."

Oz came to the Georgia Aquarium from the Oregon Zoo when it opened in 2005. The furry old-timer leaves behind three otter companions, Brighton, Bixby, and Cruz.

According to the aquarium's website, sea otters' life span is estimated to be 15 to 20 years for females and 10 to 15 years for males in human care. The average lifespan is approximately 10 to 12 years in their natural habitat.

"Oz lived a long, loved life and was an important ambassador for his endangered species," the aquarium continued on Twitter. "He will be deeply missed."

Rest in peace, sweet Oz!
