PANAMA CITY BEACH, Fla. (AP) - A California Sea Lion named Floater has been euthanized because of an invertebral disc disease.
The News Herald of Panama City ( reports Floater died Saturday at the Panama City Beach attraction.
The disease causes progressive paralysis and is common in sea lions.
Officials say 30-year-old Floater was one of the first animals acquired when Gulf World opened in 1984.
Employees and visitors stopped by the park to say goodbye to show their respects to the sea lion over the weekend.
In a news release, Gulf World said Floater "will be missed immensely, by our guests and even more by our animal care team and trainers."
