SANCHEZ, Alberto J.; FLORIDO, Rosa; ALVAREZ-PLIEGO, Nicolás  and  SALCEDO, Miguel Ángel. Distribution of Pterygoplichthys spp. (Siluriformes: Loricariidae) in the low basin of the Grijalva-Usumacinta rivers. Rev. Mex. Biodiv. [online]. 2015, vol.86, n.4, pp.1099-1102.

The records of 3,967 specimens of Pterygoplichthys spp. in 6 associations of aquatic macrophytes in 6 areas of wetlands confirm its dispersion in the lower basin of the Grijalva-Usumacinta rivers. The loricariids in submerged rooted vegetation need attention, since they represent another risk for these associations of aquatic macrophytes, which shelter high biodiversity.
