Those two exhibits have been replaced. There's a new Jelly Exhibit in near the Outer Bay, as well as a Sea Horse exhibit. One of the surrogate otters recently died, so the sea otter exhibit has now been closed off. The Outer Bay has been renovated (nothing much has changed, just maintenance) and they're building a new restaurant. Also, I don't know if you were visiting during those times, but Monterey Bay Aquarium is now the only Aquarium worldwide to have housed six (not all at once) juvenile Great White Sharks. I've seen three of them.
