359:, usually 80 mm in length (although very large individuals can reach 155 mm). Its snout shape is variable depending on whether it lives on a stream or wetland habitat. It has large pectoral and pelvic fins, and a dorsal fin that starts forward of the anal fin. It is orange-brown to olive-brown with very variable dark brown markings that can be speckles, spots, or irregular bands, and its skin is heavily dusted with gold. Sometimes it has a small black patch behind the gill cover (

It is slow growing, reaching maturity at one (males) or two years (females). Females produce low numbers of large eggs during October. Spawning occurs at the stream edge in
