Sea creatures surround you the minute you hand over your ticket at this extraordinary facility: right at the entrance dozens of them swim in a three-story-tall, sunlit kelp-forest tank. All the exhibits here provide a sense of what it's like to be in the water with the animals—sardines swim around your head in a circular tank, and jellyfish drift in and out of view in dramatically lighted spaces that suggest the ocean depths. A petting pool puts you literally in touch with bat rays, and the million-gallon Open Seas tank illustrates the variety of creatures, from sharks to placid-looking turtles, that live in the eastern Pacific. At the Splash Zone, which has 45 interactive bilingual exhibits, kids can commune with African black-footed penguins, potbellied seahorses, and other creatures. The only drawback to the aquarium experience is that it must be shared with the throngs that congregate daily, but most visitors think it's worth it. Opening in 2016, the ¡Viva Baja! Life on the Edge exhibit will explore the delicate balance of life where the sea meets the sand in Baja, Mexico. Another must-see is Tentacles: The Astounding Lives of Octopuses, Squid, and Cuttlefishes, a huge and fascinating display of marine mollusks.
