Size93mm or 3.7" SL. Find near, nearer or same sized spp.
IdentificationMost amphiliid species are found in fast-flowing water of clear, rocky streams at high elevations or rapids of large lowland rivers (Berra 2001; Roberts 2003).basins (Seegers et al. 2003). Species of Amphilius are adapted for fast flow and rocky habitats (Skelton 1986). Morphological adaptations for these habitats include expanded pectoral and pelvic fins with a thickened first ray, depressed body, dorsally directed eyes and reduced swim bladder (Skelton 1986; Walsh et al. 2000). The large pelvic fins form, in conjunction with the body, a feeble sucking disc that enables the fish to cling to rocks (Jackson 1961b).
