Stiphodon carisa Watson 2008

Predorsal scales sexually dimorphic in number: male with 5-11 and female with 8-16; slightly embedded cycloid scales present on belly. Male with a triangular-shaped first-dorsal fin withthird and/or fourth spines longest but not filamentous and a patch of white fatty tissue posterior to pectoral-fin base. Female usually with 5 (4-5) dusky to blackish blotches or spots along lateral midline from second-dorsal fin with usually 4 (3-4) posterior-most spots positioned close together on caudal peduncle, dusky band extending from anterior to eye to upper hypural base usually indistinct posterior to pectoral-fin base, with or without a dusky or black gular blotch, and in some females xanthism exists which fades in preservation and in life yellow with orange to bright red markings (Ref. 74937).

Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

Stiphodon carisa is collected over gravel in a wide, shallow medium-sized river with gravel riffles and sandy runs (Ref. 74937).
