Goldfish (Carassius auratus) was originally native to the Orient, but now is a worldwide popular aquarium fish. Although related to the Eurasian Carp, this is a distinct species as can be easily observed by studying the shape of the mouths of the two species.  Many unusual shape and color forms have been created of this interesting and hardy species.

Carp Family, Cyprinidae, is a group of freshwater fishes that  contains the carp, the familiar goldfish, the bream, and many  other kinds of fish.

Order Cypriniformes contains the majority of the world's  freshwater species of fish. Included in this order are the  minnows, carp, and many other groups of fish.

Bony fish, Class Teleostomi, are a class of chordates that  include the majority of fish-like animals found on earth. They  are characterized by a bony jaw and a bony skeleton. They are  found in both fresh and marine waters.

Backboned Animals (Phylum Chordata) are the most advanced group of animals on earth. These animals are characterized by having a spinal cord or backbone. Most members have a clearly defined brain that controls the organism through a spinal cord. Fish, amphibians, reptiles, birds, and mammals are in this phylum.

Currently, some taxonomists believe that the fish should be divided into two groups (sharks and regular fishes) and that there are some other primitive groups in the phylum such as hagfish or lampreys.

Animal Kingdom contains numerous organisms that feed on other animals or plants. Included in the animal kingdom are the lower marine invertebrates such as sponges and corals, the jointed legged animals such as insects and spiders, and the backboned animals such as fish, amphibians, reptiles, birds, and mammals.
