Ecology Summary - Sternarchogiton zuanoni
Ecology of Sternarchogiton zuanoni
 
Main Ref. de Santana, C. D. and R. P. Vari, 2010
Remarks Available specimens of Sternarchogiton zuanoni were captured in Cachoeira de Kaituká at locations in rapids and in pools at the base of waterfalls. Sternarchogiton zuanoni is the sole species known to be associated with rapidlyflowing rivers with rocky beds, whereas the examined samples of other congeners originate from main channels of deep-water rivers, often in benthic settings (de Santana and Crampton, 2007). Three other species of the Apteronotidae, Megadontognathus kaitukaensis (Campos-da-Paz, 1999) and two undescribed species of Sternarchorhynchus (de Santana and Vari, in press), were also captured within Cachoeira de Kaituká (Ref. 83662).
