Unique Spanish aquarium
L'Aquarium de Barcelona was the first one built in Spain in which you could walk through a glass tunnel while all sorts of species, including some sharks, swam around you. It's a unique experience, definitely worth trying. Besides that part, there are plenty of other aquariums that house many species from all the oceans and some rivers. I've brought you a small sample of species that can be seen if you visit here.
