freshwater fish found in central and east-central South America. Despite having "Salminus" in its name, the dorado is not related to any species of salmon, nor to the saltwater fish also called dorado. It is very popular among recreational anglers and supports large commercial fisheries.

Serrasalmidae is a family of
fishes, recently elevated to family status. It includes about 94 species. The name means "serrated salmon family", which refers to the serrated keel running along the belly of these fish. Fish classified as Serrasalmidae are also known by these common names: pacu, piranha, and silver dollar. These common names generally designate differing dental characteristics and feeding habits.
Serrasalmids are medium- to large-sized
fishes that reach about long, generally characterized by a deep, laterally compressed body with a series of midventral abdominal spines or scutes, and a long dorsal fin (over 16 rays). Most species also possess an anteriorly directed spine just before the dorsal fin extending from a supraneural bone; exceptions include members of the genera "Colossoma", "Piaractus", and "Mylossoma".
"Santanichthys" is a small,
fish that would have superficially resembled more advanced tetras or the unrelated herrings. Maximum length appears to be around 3-4 centimeters standard length. The species possesses a primitive but complete Weberian Apparatus, formed from the first four vertebrae of the spinal column. This is the earliest occurrence of the structure found in any known taxon of fish. Anatomically, the fish is similar to many others within its order. The body is semi-laterally compressed and ovate. The fins are more or less complete for a
- "Santanichthys" possesses a single dorsal, anal and caudal fin and paired pectoral and pelvic fins. Skeletal-wise, the fish has from 30-40 elongated vertebrae. A complex suspensorium can be found in the taxon. Jaw teeth however, are noticeably absent. Cycloid scales are wholly present throughout the entire body.
Cynodontidae, also known as dogtooth characins or vampire tetras, are a family of predatory,
freshwater fishes from South America. This group is not very diverse, and includes only five genera and 14 species. Most of what is known about this family is from the members of the subfamily Cynodontinae, which includes the largest species of this family, up to . The members of subfamily Roestinae are less known, though they only reach up to .
The Chilodontidae, or headstanders, are a small family of freshwater
fishes found in northern and central South America. This family is closely related to Anostomidae and is sometimes treated as a subfamily, Chilodontinae, within the Anostomidae family. Due to issues of homonymy with the gastropod family Chilodontidae, one of the families must be changed, possibly by having the fish family revert to Eigenmann's original name of Chilodidae. See here for a discussion regarding this issue.
Santanichthys diasii is a species of extinct fish that existed around 115 million years ago during the Albian epoch. "S. diasii" is regarded as the basal-most
, and is the earliest known member of Otophysi. It appears as a small fish, similar in appearance to a modern-day herring little more than 30 millimeters in length. Its most striking characteristic is the presence of a Weberian apparatus, which makes it the most primitive known member of the order Characiformes, the order in which modern-day tetras (including piranhas) are classified. "Santanichthys" has been unearthed from numerous locations throughout Brazil, in rocks dating to the Cretaceous Period. Its presence in these strata is seen as an indicator for the biogeography and evolution of its order.
"Santanichthys diasii" is the only species within the genus "Santanichthys". It is classified in the order Characiformes, an order that includes the tetras. Analysis of its morphological characters, including the presence of enlarged lagenar capsules has placed it as one of the most basal characiforms. This, combined with the Early Cretaceous origin of these specimens, makes "Santanichthys" the earliest known otophysan; The next characiforms up the fossil record date from the Late Cretaceous period already. This has several implications on the evolution of the Characiformes. All modern characiforms are strictly freshwater species. The Santana Formation is a marine sedimentary formation and thus "Santanichthys" was most likely an inhabitant of brackish or marine waters. This supports a marine-to-freshwater model of the evolution and dispersal of
species from the breakup of the continent Gondwana (Africa and South America) to the present day.
