The meeting of the warm current from the Mediterranean and the cold current from the Atlantic Ocean means the Strait of Gibraltar is one of the biologically diverse places in the world with its waters hosting up to ten different species of whales and dolphins. This display presents the range of species of cetaceans that inhabit the Mediterranean. The exhibition has replicas of cetaceans in synthetic resins, as well as real skeletons that allow visitors to get up close with the anatomy of these species.

They'll also find out information about cetaceans, such as the fact that they are not fish, but mammals that nurse their young.

They'll also learn that, although they live in water, they breath with their lungs using orifices or blowholes they have on their head; their navigation system, which is based on echolocation similar to sonar used by submarines, is unique amongst marine animals; they sleep with half of their brain awake to be able to breath and not drown; and they have one of the largest and most complex brains of the animal kingdom.
