Hiodon tergisusHiodon tergisus, the mooneye, is a freshwater fish that is widespread across eastern North America.
HiodontiformesHiodontiformes is an order of ray-finned fish consisting of the two living species of the mooneye family, Hiodontidae, and three extinct genera. These are traditionally classified within the order Osteoglossiformes, a placement some authorities still follow. Fossil study of the extinct genus Yanbiania suggests that the hiodontids separated from other osteoglossomorphs early and thus may deserve a separate order.
CrustaceanCrustaceans (from Latin word "crustacea" meaning: "those with shells" or "crusted ones") are mandibulatearthropods that are traditionally a part of the paraphyleticsubphylumCrustacea (). Crustaceans are mainly aquatic, including decapods (shrimps, prawns, crabs, lobsters, and crayfish), seed shrimps, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, opossum shrimps, amphipods and mantis shrimp.
OsteoglossiformesOsteoglossiformes, meaning "bony tongues" in Ancient Greek, is a relatively primitive order of ray-finned fish that contains two sub-orders, the Osteoglossoidei and the Notopteroidei. All of at least 245 living species inhabit freshwater. They are found in South America, Africa, Australia and southern Asia, having first evolved in Gondwana before that continent broke up.

Iris (anatomy)The iris (pl.: irides or irises) is a thin, ring-shaped structure in the eye in most mammals and birds that is responsible for controlling the diameter and size of the pupil, and thus the amount of light reaching the retina. In optical terms, the pupil is the eye's aperture, while the iris is the diaphragm. Eye color is defined by the iris.
Family (taxonomy)Family (Latin: familia, pl.: familiae) is one of the eight major hierarchicaltaxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus.

ActinopterygiiClass of ray-finned bony fishesActinopterygii ( ; from Ancient Greek ἀκτίς (aktís) 'ray, beam' and πτέρυξ (ptérux) 'wing, fins'), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that constitutes nearly 99% of the over 30,000 living species of fish. The vast majority of extant actinopterygian species are teleosts, and by species count they dominate the subphylumVertebrata, comprising over 50% of all living vertebrates.
GoldeyeThe goldeye (Hiodon alosoides) is a freshwater fish found in Canada and the Upland South plus central United States. It is one of only two extant species in the family Hiodontidae, the other species being Hiodon tergisus. The species name alosoides means shad-like. It is also called Winnipeg goldeye, western goldeye, yellow herring, toothed herring, shad mooneye, la Queche, weepicheesis, or laquaiche aux yeux d'or in French.
AlosidaeThe Alosidae, or the shads, are a family of clupeiform fishes. The family currently comprises five genera worldwide, and about 33 species. The shads are pelagic (open water) schooling fish, of which many are anadromous or even landlocked. Several species are of commercial importance, e.g. in the genus Alosa (river herrings), Brevoortia (menhadens), and Sardina. The Alosidae were previously included in the herring family Clupeidae.*As an Amazon Associate I earn from qualifying purchases.
