One of the beloved creatures at Fresno's Chaffee Zoo has died.
'Buck' the harbor seal died overnight after several days of declining health.
Buck has been at the Chaffee Zoo for nine years and just recently moved into the new Sea Lion Cove exhibit.
He came to Fresno from Six Flags Worlds of Adventure in Ohio.
Last year, successful cataract surgery restored Buck's vision after years of blindness.
At 27 years of age, buck was considered an older member of his species.
The zoo is now performing tests to determine the exact cause of his death.
