Actinopterygii - Actinopterygii Ray-finned fish Atlantic herring Scientific classification Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Orders Many: see text The Actinopterygii are the ray-finned fish. They are the dominant group of vertebrates, with over 27,000 species ubiquitous throughout freshwater and marine environments. They are traditionally treated as a subclass of the Osteichthyes, or bony fish, but as that group is paraphyletic they may be treated as a full class. Traditionally three grades of Actinopterygii have been recognized: the Chondrostei, Holostei, and Teleostei. The second is paraphyletic and tends to be abandoned, however, while the first is now restricted to those forms closer to extant Chondrostei than to the other groups. Nearly all fish alive today are teleosts. A listing of the different groups is given below, down to.
Vertebrate - extinct Chondrichthyes (cartilaginous fish) Acanthodii - extinct Actinopterygii (ray-finned fish) Actinistia (coelacanths) Dipnoi (lungfish) Amphibia (amphibians) Reptilia (reptiles) Aves (birds) Mammalia (mammals) Vertebrata is a subgroup of chordates, specifically, those with backbones or spinal columns. Vertebrates are definied as chordates whose notocord is protected by bones called vertebrae, sometimes referred to as a vertebral column. Vertebrata is the largest and most advanced subphylum, and contains most of the animals with which we are familiar. Fish (including lampreys but excluding hagfishes), amphibians, reptiles, birds, and mammals (including humans) are vertebrates. Additional characteristics of the subphylum are a muscular system that mostly consists of paired masses, as well as a central nervous system which is partly located inside the backbone. The internal skeleton which defines vertebrates consists of cartilage or bone, or in.
Jack Dempsey (fish) - Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Order: Perciformes Family: Cichlidae Genus: Cichlasoma Species: octofasciatum Binomial name Cichlasoma octofasciatum The Jack Dempsey (Cichlasoma octofasciatum) is a cichlid fish. The Jack Dempsey is a popular aquarium fish, though it is not easy to keep because like many cichlids it can be highly aggressive (its name is taken from the boxer Jack Dempsey). The fish is native to Yucatan and Central America, where it is found in slow-moving waters, such as swampy areas with warm, murky water, weedy, mud- and sand-bottomed canals, and drainage ditches. It is also established as an introduced species in Australia, the USA and Thailand (presumably as an aquarium escape). It can reach up to 25cm in length, and has an iridescent greenish colour. It is carnivorous, eating worms, crustaceans,.
Jellynose fish - Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Order: Ateleopodiformes Family: Ateleopodidae Species Ateleopus indicus Ateleopus japonicus Ateleopus natalensis Ateleopus purpureus Ateleopus tanabensis Guentherus altivelis Ijimaia antillarum Ijimaia dofleini Ijimaia loppei Ijimaia plicatellus Parateleopus microstomus The jellynose fishes are a small order (Ateleopodiformes) of ray-finned fish, consisting of a single family (Ateleopodidae) with about a dozen species in four genera. Jellynoses are deep-water marine fish. Their skeletons are largely cartilage (thus the name), although they are true teleosts, and not at all related to Chondrichthyes. Heads are large, with a bulbous nose, and the (usually) elongated body tapers towards the tail. Their caudal fins are very small, and merged with long anal fins, and the pelvic fins are single rays, except for Guentherus. Dorsal fins tend to be prominent and placed just behind.

Hingemouth - Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Order: Gonorhynchiformes Family: Phractolaemidae Genus: Phractolaemus Species: ansorgii Binomial name Phractolaemus ansorgii The hingemouth (Phractolaemus ansorgii) is a small freshwater fish that is only found in west central Africa, the sole member of the family Phractolaemidea. The mouth can extended like a small trunk, thus the name, and the swim bladder can function as a lung, allowing the hingemouth to survive in oxygen-depleted environmnets..
Hiodontiformes - Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Order: Hiodontiformes Families Hiodontidae (mooneyes) Hiodontiformes is a relatively new order of fish, consisting of the two living species of the mooneye family Hiodontidae and three genera of extinct types. These are traditionally classified with the Osteoglossiformes, and many authorities still do, but fossil study of the extinct Yanbiania suggest that the hiodontids separated from other osteoglossiforms early, and thus belong to a separate order..
Horseface Loach - Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Order: Cypriniformes Family: Cobitidae Genus: Acantopsis Species: choirorhynchus Binomial name Acantopsis choirorhynchus The Horseface Loach (or Horsehead Loach) is the freshwater fish, Acantopsis choirorhynchus, in the Family Cobitidae (Loaches). This bottom-dwelling fish is from Malaysia and is similar to the Longnose Loach (Acantopsis octoactinotos), from which it can be distinguished first by the down-turned (horse-like) nose. The Horseface Loach buries itself in the bottom substratum (if silt or fine-sand), the Longnose Loach does not. The Horseface Loach is fast moving, the Longnose rather slow. However, the Longnose is more aggressive, regularly feeding on juvenile fishes. The Horseface Loach becomes most active at night and attains a maximum size of 22 cm (8") in length, but is considered mature from 6 cm (2"). It has not.

The living members of the order are all in a single family Lepisosteidae with seven species in two genera. While fossils indicate that some extinct species were marine, the living types are all in the fresh waters of eastern North America, Central America, and the Caribbean islands. Gar bodies are elongate, heavily armored with ganoid scales, and fronted by similarly elongate jaws filled with long sharp teeth. Tails are heterocercal, and the dorsal fins are close to the tail. All the gars can be large,.

Goldfish - Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Order: Cypriniformes Family: Cyprinidae Genus: Carassius Species: auratus Binomial name Carassius auratus The goldfish (Carassius auratus) is one of the earliest fish to be domesticated and still one of the most commonly-kept aquarium fish. A smallish member of the carp family, the goldfish is native to east Asia. Part of its popularity is due to the goldfish's hardiness. It is a cold-water fish, and can live in an unheated aquarium or in an outdoor fishpond. In a pond, it will even survive brief periods of being iced over. Selective breeding has produced several colour variations, some of them far removed from the "golden" colour of the original. There are also different body shapes, fin and eye configurations. Such extreme versions of the goldfish do need.
