AquaRio: The Largest Aquarium in South America


Earlier this month – on November 9th – the largest marine aquarium in South America, AquaRio, opened its doors in Porto Maravilha, Rio de Janeiro. This ambitious building extends over 26,000 square metres and is home to 28 tanks that together hold a total of 8,000 fish.

When buying tickets at the entrance, the first thing visitors will appreciate is the stunning skeleton of a humpback whale that ran aground and died in Praia da Macumba in 2014. The tour itself begins with a walk down a central aisle surrounded by incredible marine wildlife – manta rays, seahorses, gigantic groupers, and countless other species can be seen. The journey through the aquarium is further enriched by accompanying information about the animals and their natural habitats.

The main attraction is undoubtedly the oceanic tank, where bull sharks, oceanic whitetip sharks, and manta rays are swimming together. Visitors will certainly have a unique experience in this place as they observe these magnificent species from large windows and an underwater tunnel 20 metres long.

The total cost of this stunning project was US$40 million and it was recently remodeled on the occasion of the Rio 2016 Olympic Games. The aquarium also has an area for research, run in collaboration with the Department of Marine Biology at the Federal University of Rio de Janeiro.
