The river is approximately 510 kilometres (320 mi) long and passes through or borders the states of Mexico, Hidalgo, Querétaro, San Luis Potosí, Tamaulipas, and Veracruz. According to the Atlas of Mexico, it is the fourth-largest river in Mexico by volume of runoff, and forms the sixth-largest river basin in Mexico by area.
Luciobarbus bocagei is a ray-finned fish species in the family Cyprinidae. Its scientific name honours the Portuguese zoologist and politician Jose Vicente Barboza du Bocage. It is here placed in Luciobarbus following the IUCN, but that genus is very closely related to the other typical barbels and perhaps better considered a mere subgenus of Barbus. The Ebro barbel and Andalusian barbel were formerly included in L. bocagei as subspecies.
Capoeta, also known as scrapers, is a genus of fish in the family Cyprinidae found in Western Asia. The distribution extends from Turkey to the Levant, to Transcaucasia, Iraq, Turkmenistan, in Armenia, particularly in lake Sevan and northern Afghanistan. This genus is most closely related to Luciobarbus and in itself is divided into three morphologically, biogeographically and genetically distinct groups or clades: the Mesopotamian clade, the Anatolian-Iranian clade and the Aralo-Caspian clade.
Rasboroides vaterifloris, known as the pearly rasbora, vateria flower rasbora or fire rasbora, is a species of freshwater cyprinid fish endemic to Sri Lanka. It can be found in the shallow waters of shaded, slow-flowing clear streams with a silt substrate. It also prefers areas with plentiful leaf debris. Its diet consists of detritus and terrestrial insects. This species can reach a length of 4 centimetres (1.6 in) TL. It can also be found in the aquarium trade.
Squalius alburnoides is a species of fish in the family Cyprinidae. It is found in Portugal and Spain. Its natural habitats are rivers and intermittent rivers. It may be threatened by habitat loss.
Squalius is a genus of fish in the family Cyprinidae found in Europe and Asia. Hybridization is not rare in the Cyprinidae, including this genus. S. alburnoides is known to be of ancient hybrid origin, with the paternal lineage deriving from a prehistoric species related to Anaecypris; the latter mated with ancestral S. pyrenaicus. Present-day S. alburnoides mates with sympatric congeners of other species.
Squalius aradensis is a ray-finned fish species in the family Cyprinidae, growing to 13 cm (5.1 in) SL. It is endemic to Portugal where it is found in only three river basins: Arade, Algibre, and Bordeira basins. It is threatened by water extraction, drought, and introduction of exotic fish species.
Squalius keadicus is a species of fresh-water fish in the family Cyprinidae. It is found only in Greece, and known as the menida in Greek.

Squalius janae, commonly known as the Istrian chub, is a species of freshwater fish in the carp family Cyprinidae. It was first described in 2010 from the Dragonja River drainage in Slovenia. Since then they have also been found in the Boljunčica and Pazinčica river drainages in Istria, Croatia.
Squalius valentinus, commonly known as the Valencia chub and the Levantine bagra, is a species of freshwater fish in the carp family Cyprinidae. It was first isolated from the Turia River in Valencia, hence its name. It is considered endangered. This species is differentiated from its cogenerates by having eight branched rays in its dorsal fin; eight branched rays in its anal fin; two rows of pharyngeal teeth on both sides possessing 2 and 5 teeth ; a wide caudal peduncle; its number of gill rakers; the number of scales in its lateral line; the number of scale rows above the latter; by possessing three scale rows below it; by having thirty-nine vertebrae ; showing large 4th and 5th infraorbital bones; a maxilla with a very distinct marked anterior process; exhibiting a frontal bone expanded at the middle; a wide neurocranium bone; the lower branch of the pharyngeal bone being robust; a large and narrow urohyal; as well as genetic differences (allozymes).
Squalius malacitanus, commonly known as the Málaga chub, is a species of freshwater fish in the carp family Cyprinidae. It was first isolated from the Guadalmina River in Málaga, hence its name. It is considered a vulnerable species. S. malacitanus differs from its cogenerate species by having 7–8 branched rays in its dorsal fin, 8 branched rays in the anal lateral line; the number of scale rows above its lateral line; possessing 3 scale rows below its lateral line; 38 vertebrae, 21 abdominal, and 17 caudal; large fourth and fifth infraorbital bones; maxilla without a pointed anterior process; the middle of its frontal bone being narrow, as well as its neurocranium bone; the lower branch of its pharyngeal bone is rather long; and the shortness of the inferior lamina of its urohyal bone.
Capoeta razii, is a newly described species of freshwater cyprinid fish occurring mainly in the southern Caspian Sea basin, Iran.
