The open sea

Welcome to the deep blue !

You were hoping to see some sharks? Here they are! Observe the grey shark cruising its patch; see how the leopard shark got its name. Yet, the other residents don't seem particularly alarmed and dance their multicoloured ballet unperturbed. One could spend hours, mesmerised by the oversize window of the main tank.

Both male and female

The humphead wrasse (also called Maori wrasse) is hermaphrodite. The process by which they change sex is not well understood yet, but scientists know that they are all born female, and some become male with age. When this takes place, their colour changes and the characteristic hump on the front of their head becomes more pronounced.

He can smell it

The sharks' sense of smell is one of the most sensitive of the animal kingdom. A shark can smell the presence of prey from several kilometres away. The water that enters its nostrils circulates inside a "smelling pouch", and the animal can detect a few drops of blood diluted in millions of litres of water.

Cut !

The surgeonfish get their name from the razor-sharp spur which adorns the base of their tail. When threatened, they deploy these spurs to try to wound the aggressor.
