Cunning, camouflage, strength or speed: predators have the major trump cards. But one day or another, they will face stronger ones, for predation takes place at all levels of the food chain.
The Aquarium's tropical area reflects the fantastic world of the coral reef, and the spectacular life in warm seas.
Different species show their varied shapes and striking colours, resulting from their adaptations to the requirements of the environment, and to different modes of life.
Inside the tanks, they move about in harmony with their surroundings similar to their original environment. In ideal conditions, many fishes and invertebrates breed. They do not encounter natural predators: therefore they often live longer. Some fishes reach a very old age and astounding sizes.
The largest move about in a tank nicknamed "happy retirement", housing tropical as well as Mediterranean species. A bluering angelfish lived over 27 years in the Aquarium: it was for a long time the doyen of the tropical area.
"The world is a book, and those who do not travel read only a page", St. Augustine said. Here at www.travel-university.org we believe that every page must be read and explored. Travel is an avenue of learning that no text or classroom can teach. The world is a living classroom and you the student. We invite you to the www.travel-university.org library where you can read general interest and detail oriented articles.
