We visited the Acqua Mundo aquarium which is the largest aquarium in South America. It is perched on the beach, and it's filled with mini-lakes and tanks for penguins, caimans and even albino snakes. We watched some adventurous divers hand feed some of the creatures. It took us 1 1/2 hours to get to Guarujá from Santos and we spent a half hour at the aquarium. There were so many huge trucks on the highway that traffic was stopped. We were told that the trucks going to the port to unload their containers have to park in a certain area and wait to be called for their turn in the port so that was what the holdup was all about.
