The Aquarium Cap Blanc, more popularly known as "Sa Cova de ses llagostes" must use this nickname that is traditionally gave the cave as lobster tank.
Used as a nursery, lobsters were exported to markets in Barcelona and other cities. Also preserved here surpluses that fishermen could not sell and recovered on bad weather days when fishing was not possible, not to undermine their sales.
In 1989, to condition the space, five innings of direct sea water were carried out, ensuring excellent circulation and oxygenation of water in all facilities. It became aquarium, and today you can see a representative sample of the main species of Ibizan Mediterranean, from the stately groupers to julias colorful or Fadrins.
