July 17th, 2012. This is another glimpse into the inner workings of the aquarium, and in 2008 for the first time a public viewing deck was built to allow visitors to stare down into two large, previously off-exhibit pools. Again this area is for rehabilitated animals that will be released back into the wild, and a worker told me that the inhabitants change practically every week but on my visit I saw two California sea lions who were recovering from various ailments.
