Corydoras is a genus of freshwater catfish in the family Callichthyidae and subfamily Corydoradinae. The species usually have more restricted areas of endemism than other callichthyids, but the area of distribution of the entire genus almost equals the area of distribution of the family, except for Panama where Corydoras is not present. Corydoras species are distributed in South America where they can be found from the east of the Andes to the Atlantic coast, from Trinidad to the Río de la Plata drainage in northern Argentina. Species assigned to Corydoras display a broad diversity of body shapes and coloration. Corydoras are small fish, ranging from 2.5 to 12 cm in SL., and are protected from predators by their body armor and by their sharp, typically venomous spines.
Pseudoplatystoma is a genus of several South American catfish species of family Pimelodidae. The species are known by a number of different common names. They typically inhabit major rivers where they prefer the main channels and tend to stay at maximum depth, but some species can also be seen in lakes, flooded forests, and other freshwater habitats. They have robust bodies, and are important food fish. Recently, their population size has been on the drastic decline due to a variety of factors including overfishing and habitat destruction due to the construction of hydroelectric dams.
Tetraphyllidea is a large tapeworm order that contains some 60 genera and about 800 described species. Tetraphyllideans are remarkable for their scolex morphologies, which are the most varied and morphologically complex amongst all tapeworm orders.
The Pimelodidae, commonly known as the long-whiskered catfishes, are a family of catfishes.

Pseudancistrus is a genus of suckermouth armored catfishes native to South America.
The porthole shovelnose catfish or spotted shovelnose catfish, Hemisorubim platyrhynchos, is the only species in the genus Hemisorubim of the catfish family Pimelodidae.
Steindachneridion is a genus of South American pimelodid catfish.
Neoplecostomus is a genus of fish in the family Loricariidae native to South America. Neoplecostomus can be distinguished from all other loricariids by a modified shield of small plates on the abdomen with posteriorly directed odontodes; the shield appears to act as a holdfast. The color pattern is generally mottled brown with the abdomen white. The head is long, rounded, and shovel-shaped. The fin spines are weak. They range from about 8 to 11 cm (3.1–4.3 in) SL. The species of Neoplecostomus live in fast-flowing water.
Stegophilus is a genus of pencil catfishes native to South America.
The thorny-headed worm family Polymorphidae contains endoparasites which as adults feed mainly in fish and aquatic birds. When this taxon was erected by Meyer in 1931, a subfamily Polymorphinae was established in it. As the Polymorphidae as presently understood would then be monotypic, with no basal genera outside the Polymorphinae, the proposed subfamily is redundant for the time being and therefore most modern treatments simply omit it. Polymorphus minutus is an economically significant parasite in goose and duck farming.
Pseudoplatystoma fasciatum or barred sorubim or barred catfish is a species of long-whiskered catfish native to the Suriname, Corantijn and Essequibo. The nocturnal predator feeds mainly on other fish and crabs. Females reach a more notable size. They become sexually mature at 56 cm (22 in), males at 45 cm (18 in) and this species reaches a maximum length of 90 cm (35 in) TL. Fecundity seems to be estimated at 8 million eggs per kg, but was recently measured in aquaculture at a lower, and more likely number of 150,000 eggs laid per kg.
Myxobolus cordeiroi is a myxozoan parasite of freshwater fish.
Amphilinidae is a family of parasitic flatworms of the phylum Platyhelminthes. It is the only family in the monotypic order Amphilinidea. Amphilinids are Cestodes, yet differ from true tapeworms (Eucestoda) as their bodies are unsegmented and not divided into proglottids. "Amphilinids are large worms which have a flattened leaf-like body. Only 8 amphilinid species are known." "The adults are hermaphroditic. A muscular proboscis is located at the anterior end, and is sometimes very weakly developed or absent." They live in the body cavities of freshwater turtles and teleost fish as adults, and in the bodies of various crustaceans as juveniles. Apart from a little studied parasitism of sturgeon, these flatworms have very little economic importance. Biologically, they have gained attention for their potential to shed light on the phylogeny of tapeworms.
Ophiotaenia is a genus of tapeworms in the Proteocephalidae family.
Proteocephalinae is a subfamily of tapeworms in the Proteocephalidae family, which includes the genus Ophiotaenia.
Louis Euzet was a French parasitologist.
Kritsky is a genus of digeneans in the family Aporocotylidae or blood flukes. The name of the genus honours the American parasitologist Delane C. Kritsky.
Proteocephalus is a genus of flatworms belonging to the family Proteocephalidae.
