The zones
Sea-Spray Zone
Situated above the high-tide water mark, this zone is extremely unfriendly to both fauna and flora. Only a few species have managed to adapt to these extreme conditions: the rain, wind and salt prevent any terrestrial plant from living here. It is the world of the lichens, organisms half-way between algae and fungi, the world of animals capable of moving around.
This open-air zone allows children and adults alike to get to know the first animals of the Aquarium in the outside tank. Maritime plants which grow along the seashore embellish the visit.
Tidal Zone
Numerous fauna and flora species are found in this “seesaw” intertidal zone which is covered and uncovered by the sea twice every day. To survive here, the fauna and flora have developed clever survival tactics which only nature could imagine.
Sub-littoral Zone
The sub-littoral zone is the ultimate step in the exploration of life in the depths of the sea around the Breton coast. Living creatures are no longer subject to tidal movements but they have to face another problem which is just as important: the lack of lights!
This is the kingdom of the invertebrates (anemones, sponges, corals, gorgonian) and big fish (dogfish, rays, conger eels). These fascinating, surprising creatures can be seen in several of the landscaped tanks designed by an architect. The biggest tank holds 50,000 liters of water!
