La Rochelle's number-one tourist attraction is this state-of-the-art family-friendly aquarium. A visit begins by descending in a clunky old 'submarine' to the ocean floor, where, serenaded by the sound of crashing waves and classical music, you step out to be greeted by the pouting fish of the North Atlantic. After which you swim through the oceans and seas of the world learning about all its diverse lifeforms.
Other highlights include the huge open-ocean aquarium full of UFO-like rays and fearsome sharks, the fluro-coloured jellyfish waving tentacles in time to the classical music that wafts through aquarium, the jungle area with its tree-level walkways and ponds full of teeth-gnashing piranhas, the elegantly dancing seahorses, timid turtles and the bizarre half-newt, total-fish mudskippers. The aim is to educate visitors to the wonders of the world's waters and the threats our oceans face. You will learn how sea cucumbers spit their guts out when frightened and then just grow another set, and – here's one that all parents can relate to – how poor mummy octopus becomes so tired at the mere thought of bringing up her precious brood that she dies of exhaustion the moment they hatch out! You should allow a minimum of two hours for a visit.
