Born and raised in the city of Cáceres, a small town on the banks of the Paraguay River, in the north Pantanal of Brazil, and spent all his spare time surrounded by nature, and whether it was horse riding or fishing, his interest in wildlife was ignited.
Influenced by a childhood immersed in nature, Marcos made a natural progression to a degree in biology at the Federal University of Mato Grosso (UFMT). He also had the opportunity to conclude, in his final essay, a project about the biodiversity of reptiles and amphibians in the northern Pantanal. His interest in herpetology and understanding of natural systems was ever increasing until in 2010 he entered the post-graduate Management and Environmental Expertise Course, which allowed him to work with mitigation of impacts in an area of riparian vegetation. In 2011, Marcos was able to register for a Master's degree in Ecology and Biodiversity Conservation, where he worked with environmental variables influencing the biodiversity of amphibians.
His gentle nature and exceptional knowledge of The Pantanal ecosystems make him an asset on any tour to the region. Aside from his activities as a Naturalist tour guide, Marcos also worked as a singer and actor in a group of male voices known as Alma de Gato, and also as a photographer in his spare time.
