Wednesday, Barker cut the ribbon at the newly restored visitors area. In his honor, it's been re-named Bob Barker Marine Mammal Viewing Area.
The center has been helping in marine mammal rescue for 40 years.
Wednesday the center also named a rescued sea lion "Barker" that Bob helped release back into the ocean following her successful medical rehabilitation.
