The National Aquarium houses a reef tank, a travelator which spirals its way beneath the enormous oceanarium, creating the impression of a true underwater experience, and a typical New Zealand rocky shore environment. There are sharks, stingray and hundreds of fish species along with eels, trout, sea horse, turtles, tropical marine fish, kiwi, tuatara, and a crocodile on display. There is also a cafe and themed souvenir shop.
