Simon Bellingham

Simon is originally from Zimbabwe where as a child he developed a passion for big cats and all things natural. Simon began his professional guiding career in South Africa working in a number of famed private wildlife reserves before becoming an international wildlife guide. He is now certified with the most advanced level of his profession in South Africa. When Mario and Simon met, they drew up a plan on how to promote and develop ecotourism in Brazil. After several visits to the Pantanal it was clear that for any plan to work the Jaguar had to be included, hence arose the idea to habituate the Jaguars. Simon has been involved in the Jaguar Habituation/Oncafari Project since inception and regularly visits the Pantanal bringing his global experience and new ideas on how to best achieve our goals.

Mario Nelson Cleto

Born and raised in the city of Aquidauana (state of Mato Grosso do Sul), Mario has always been close to the nature of the Pantanal.
At the age of 20, he was hired to work with the maintenance of the Caiman Ecological Refuge and did a little bit of everything. At the refuge, he met the Onçafari Project researchers and with their help learned that jaguars must be respected. He then began to observe these animals at sunset. Eventually, he was hired by Onçafari as a field guide.
Today he takes tourists around the forest, crosses rivers and lagoons, and shows them not only the jaguars, but also anteaters, macaws, tuiuiú birds, pampas deer, and blue herons. He also participates in captures together with veterinarians and biologists. He used to be afraid of jaguars. Now, he is afraid they will be extinct.
