The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. The caudal fins of C. dimerus are characterized as having a web-like pattern of dark bands and caudal rays with the clear spaces between the rays and bands being larger in the upper caudal than the lower caudal fin; by contrast, the caudal fins of C. bimaculatum have pale bands and the appearance of a symmetrical dotted pattern (Robins et al. 20 per page . 2011, Pandolfi et al.

They are tolerant of low dissolved oxygen that may kill most other species (Staeck and Linke 1995) and have been observed dispersing through extremely shallow water at the beginning of the rainy season (Sucksdorff 1981, in Kullander 1983). These differences may reflect seasonal use, habitat availability, interspecific competition, or predator avoidance and support the generalist tendencies of this species. The aim of this study was to characterize male reproductive physiology by measuring steroid hormone plasma levels and analyzing testes cellular composition. Journal of Zoology 252(4):481-493.
