Ascocotyle Pindoramensis
''Ascocotyle pindoramensis'' is a fluke in the genus '' Ascocotyle'' that occurs along the eastern coast of the Americas from Brazil to Nicaragua, Mexico, Louisiana, and Florida and doubtfully in Egypt.Simões et al., 2006, p. 505 It occurs in the intestine of its definitive hosts. Hosts recorded in the wild include the least bittern (''Ixobrychus exilis''), roseate spoonbill (''Platalea ajaja''), great blue heron (''Ardea herodias''), striated heron (''Butorides striatus''), stripe-backed bittern (''Ixobrychus involucris''), yellow-crowned night heron (''Nyctanassa violacea''), black-crowned night heron (''Nycticorax nycticorax''), osprey (''Pandion haliaetus''), Neotropic cormorant (''Phalacrocorax brasilianus''), and marsh rice rat (''Oryzomys palustris''). In the marsh rice rat, it infected 9% of rats examined in a 1970–1972 study in the salt marsh at Cedar Key, Florida, but none in a freshwater marsh.Kinsella, 1988, table 1 ''A. pindoramensis'' has been ...

Trematode
Trematoda is a class of flatworms known as flukes. They are obligate internal parasites with a complex life cycle requiring at least two hosts. The intermediate host, in which asexual reproduction occurs, is usually a snail. The definitive host, where the flukes sexually reproduce, is a vertebrate. Infection by trematodes can cause disease in all five traditional vertebrate classes: mammals, birds, amphibians, reptiles, and fish. Etymology Trematodes are commonly referred to as flukes. This term can be traced back to the Old English name for flounder, and refers to the flattened, rhomboidal shape of the organisms. Taxonomy There are 18,000 to 24,000 known species of trematodes, divided into two subclasses — the Aspidogastrea and the Digenea. Aspidogastrea is the smaller subclass, comprising 61 species. These flukes mainly infect bivalves and bony fishes.https://www.biotaxa.org/Zootaxa/article/view/zootaxa.3918.3.2 Digenea — which comprise the majority of trematodes — ...

House Mouse
The house mouse (''Mus musculus'') is a small mammal of the order Rodentia, characteristically having a pointed snout, large rounded ears, and a long and almost hairless tail. It is one of the most abundant species of the genus '' Mus''. Although a wild animal, the house mouse has benefited significantly from associating with human habitation to the point that truly wild populations are significantly less common than the semi-tame populations near human activity. The house mouse has been domesticated as the pet or fancy mouse, and as the laboratory mouse, which is one of the most important model organisms in biology and medicine. The complete mouse reference genome was sequenced in 2002. Characteristics House mice have an adult body length (nose to base of tail) of and a tail length of . The weight is typically . In the wild they vary in color from grey and light brown to black (individual hairs are actually agouti coloured), but domesticated fancy mice and laboratory mice ar ...

List Of Parasites Of The Marsh Rice Rat
A variety of parasites have been recorded from the marsh rice rat (''Oryzomys palustris''), a semiaquatic rodent found in the eastern and southern United States, north to New Jersey New Jersey is a state in the Mid-Atlantic and Northeastern regions of the United States. It is bordered on the north and east by the state of New York; on the east, southeast, and south by the Atlantic Ocean; on the west by the Delaware ... and Kansas and south to Florida and Texas, and in Tamaulipas, far northeastern Mexico. Some of these parasites are endoparasites, internal parasites, while others are ectoparasites, external parasites. Parasitology, Parasitologist John Kinsella compared the endoparasites of marsh rice rats in a saltwater marsh at Cedar Key and a freshwater marsh at Paynes Prairie, both in Florida, in a 1988 study. He found a total of 45 species, a number unequaled in rodents. This may be related to the diverse habitats the rice rat uses and to its Omnivore, omnivorou ...

Tilapia (genus)
''Tilapia'' is a genus of cichlid fishes endemic to freshwater habitats in Southern Africa. In the past this was a very large genus including all species with the common name tilapia, but today the vast majority are placed in other genera.Dunz, A.R., and Schliewen, U.K. (2013). ''Molecular phylogeny and revised classification of the haplotilapiine cichlid fishes formerly referred to as “Tilapia”.'' Molecular Phylogenetics and Evolution, online 29 March 2013. Species and taxonomy In the past, ''Oreochromis'' and ''Sarotherodon'' were retained in the genus ''Tilapia'', but these are treated as separate genera by all recent authorities.Nagl, S.; Tichy, H.; Mayer, W.E.; Samonte, I.E.; McAndrew, B.J., and Klein, J. (2001). ''Classification and Phylogenetic Relationships of African Tilapiine Fishes Inferred from Mitochondrial DNA Sequences.'' Molecular Phylogenetics and Evolution 20(3): 361–374.

Cichlid
Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of ''Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Many cichlids, particularly tilapia, are important food fishes, while others, such as the ''Cichla'' species, are valued game fish. The family also includes many popular freshwater aquariu ...

Xiphophorus
''Xiphophorus'' is a genus of euryhaline and freshwater fishes in the family Poeciliidae of order Cyprinodontiformes, native to Mexico and northern Central America. The many ''Xiphophorus'' species are all known as platyfish (or platies) and swordtails. Platyfish formerly were classified in another genus, ''Platypoecilia'', which is now obsolete. The type species is ''X. hellerii,'' the green swordtail. Like most other new world Poeciliids, platies and swordtails are live-bearers that use internal fertilization and give birth to live young instead of laying eggs like the bulk of the world's fishes. The name ''Xiphophorus'' derives from the Greek words ξίφος (dagger) and φόρος (bearer), referring to the gonopodium on the males. All are relatively small fishes, which reach a maximum length of depending on the exact species involved. Distribution and conservation status The various ''Xiphophorus'' species range from the southern Rio Grande basin in Mexico, through ...

Poecilia Vivipara
''Poecilia vivipara'', sometimes called the southern molly, is a small euryhaline livebearer fish distributed along the Atlantic coast of South America. It is most frequently found in standing brackish water. It has been introduced outside its native range to control mosquito populations and is occasionally kept in home aquariums. Taxonomy ''P. vivipara'' belongs to the ''Poecilia'' subgenus of the genus ''Poecilia'' and is the type species of the genus. The species most closely related to it are '' P. parae'' and '' P. picta'', which belong to the ''Micropoecilia'' subgenus. Description ''P. vivipara'' is a small poeciliid, normally growing to a size of 2-5 cm. The maximum recorded total length is 7.8 cm. Individuals from habitats with higher water salinity tend to grow faster and larger, and these differences in growth patterns are partly heritable. A factor in the size difference between freshwater populations and other populations is the high level of predation to which fre ...

Poecilia Mollienisicola
''Poecilia'' is a genus of fishes in the family Poeciliidae of the order Cyprinodontiformes. These livebearers are native to fresh, brackish and salt water in the Americas, and some species in the genus are euryhaline. A few have adapted to living in waters that contain high levels of toxic hydrogen sulfide ()Palacios, Arias-Rodriguez, Plath, Eifert, Lerp, Lamboj, Voelker, & Tobler (2013). The Rediscovery of a Long Described Species Reveals Additional Complexity in Speciation Patterns of Poeciliid Fishes in Sulfide Springs.' PLoS ONE 8(8): e71069. and a population of '' P. mexicana'' lives in caves (other populations of this species are surface-living). Some common and widespread species are often kept as aquarium fish, while other have very small ranges and are seriously threatened. All species in ''Poecilia'' are called mollies except for the Endler's livebearer (''P. wingei'') and the well-known guppy (''P. reticulata'') which have a distinctly different body shape from th ...
