The spectacular Oceanarium, which is unique in Europe, is L’Aquàrium de Barcelona’s largest aquarium and home to the greatest number of species. With a diameter of 36 metres and depth of 5 metres, it contains almost 4 million litres of water. It houses species as diverse as giltheads, moray eels, ocean sunfish, rays and two types of shark: the sand tiger shark (Carcharias taurus) and the sandbar shark (Carcharhinus plumbeus) – the real stars of L’Aquàrium de Barcelona. A transparent tunnel in excess of 80 metres in length enables you to enjoy a spectacular walk underwater. You can explore the Oceanarium from below and experience the exhilarating feeling of discovering the Mediterranean as if you were walking along the sea floor, just inches away from sharks and other curious species.
