Pterygoplichthys ambrosettii belongs to the family Loricariidae
and is considered native to the Paraguai River and the Middle
and Lower Parana River, according to Weber (1992) and
Langeani and Araujo (1993). Certain biological characteristics,
such as feeding on detritus, sediments and insect larvae,
showing parental care, construction of nests by males, rapid
growth and high fecundity (Hoover et al., 2004; Sinha et al.,
2010), as well as the capacity to tolerate environments with
poor oxygenation, favor a high capacity to adjust to living in
diverse aquatic environments, including those impacted by
dams, as observed by Marcucci et al. (2005) with other
introduced species of the armored fish in the same basin.
