Use and Trade [top]

Use and Trade: This armadillo is used as a protein source, and its carapace is used to make handicrafts.

Threats [top]

Major Threat(s): In some parts of its range, C. villosus is locally used for food and to make charangos (musical instruments; Aguiar and Fonseca 2008). It is also persecuted as a pest species in agricultural areas, and is subjected to sport hunting. Animals may also be killed on roads and by dogs (Abba et al. 2007, Abba 2008).
