[8] The black-faced lion tamarin is an arboreal species and primarily eats small fruits and invertebrates such as insect, spiders and snails.

[14][15] The Superagüi National Park covers most of the black-faced lion tamarin home ranges including Superagui Island and adjacent mainland parts of the state of Paraná.

[3] The Instituto de Pesquisas Ecológicas (IPÊ)[17] began the black-faced lion tamarin conservation program in 1996 and through 2004 focused on learning the ecology and natural history of the species.

In 2005, enough data was collected to create the first conservation action plan for the black-faced lion tamarin and its habitat.

They then hosted the first Eco-Negotiation Workshop in Ariri (São Paulo) in 2009, with a focus on education and awareness of sustainable production.

Currently some of their objectives include evaluating dispersal of young, refine the projected population, observe the effects of sea rise due to climate change, and promote sustainable harvest of heart-of-palm.
