Aquarium Pula opened in 2004 on the ground floor of the onetime Austro-Hungarian fortress in the resort complex of Verudela, a few kilometers from the city center. The aquarium was originally Croatia's first sea-turtle rescue center, which opened two years earlier. Its five rooms offer a colorful look at hundreds of sea creatures from the Adriatic's underwater world, and include a "touching pool" that allows you to touch a dogfish, turtle, sea urchin, crab, or sea squirt
during limited periods of time. There are also exhibits of fishermen's traditional equipment and of underwater photography, and children's playgroups are regularly organized on the terrace out front. For an extra fee, a three-hour boat tour on nearby waters offers an educational program on the ins and outs of oceanography.
