There is one aquarium in Ibiza (Cap Blanc) located close to San Antonio that’s built inside a cave. Inside you can see colorful fish, octopus, rays, sea horses, lobsters, and more.
Aquariums are a great place to spend a rainy day or simply as a family thing to do.
Aquarium Cap Blanc
The natural habitat aquarium is popularly known locally as Sa Cova de ses llagostes (Lobster Tank).
A wooden gangway spreads through the cave and leads you from room to room. In addition to the five main water tanks, you’ll also notice there are traditional fish tanks built into the cave walls and ceiling. These also allow natural light to seep in, illuminating the entire underwater cave.
The aquarium was originally used as a hatchery for lobsters and a sanctuary for unsold fish that were exported to markets on the mainland. Since 1989, however, it’s been converted into a tourist attraction where the main focus beyond the exhibitions is on saving species like recovering sea turtles.
The fish you can see in the cave pools are the bright and colorful species of the Ibizan Mediterranean like groupers, snappers, sea bream, and the fadrins. These are the same pretty fishies that tourists seek to find while snorkeling in Ibiza.
There are also unique exotic species like scorpionfish (ugly and poisonous), saltwater catfish, and the flying gurnard.
Alongside the fish, you’ll also be able to spot sea creatures like manta rays, eels, octopus, and sea horses, as well as crustaceans and arthropods such as lobsters and sea snails.
The underground cavern also has an area dedicated to Pitiusan marine fauna and invertebrates like sea sponges, starfish, and corals.
Besides live animals, you can also see specimens of shark eggs, sea sponges, gastropods, bivalves, and other marine invertebrates.
Registered as a Recovery Centre of Marine Species or CREM, the aquarium often acts as a hospital for sea creatures who’ve fallen victim to man-made activities like improper garbage disposal. Sea turtles are one of the most popular beneficiaries. They are given treatment and nursed back to health before being returned to the wild.
