Goldfish
The goldfish (''Carassius auratus'') is a freshwater fish in the family Cyprinidae of the order Cypriniformes. It is commonly kept as a pet in indoor aquariums, and is one of the most popular aquarium fish. Goldfish released into the wild have become an invasive pest in parts of North America and Australia. Native to China, the goldfish is a relatively small member of the carp family (which also includes the Prussian carp and the crucian carp). It was first selectively bred for color in imperial China more than 1,000 years ago, where several distinct breeds were developed. Goldfish breeds vary greatly in size, body shape, fin configuration, and coloration (various combinations of white, yellow, orange, red, brown, and black are known). History Various species of carp (collectively known as Asian carp) have been bred and reared as food fish for thousands of years in East Asia. Some of these normally gray or silver species have a tendency to produce red, oran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calico (goldfish)
Calico goldfish are goldfish of any breed that have a type of scale that is intermediate between the metallic type of scales and the transparent type. These scales have a slight sheen that produces a pearly appearance."An Interpet Guide to Fancy Goldfish" by Dr. Chris Andrews, Interpet Publishing, 2002 - "Fancy Goldfish: A Complete Guide to Care and Collecting" by Dr. Erik L. Johnson, D.V.M. and Richard E. Hess, Weatherhill, Shambala Publications, Inc., 2006 - The name "calico goldfish" came about because the first fish that were introduced with this type of scales had a mottled calico pattern with several colours. Calico goldfish often have patches of red, yellow, grey and black along with dark speckles on a blue background. This coloration usually extends over the fins. Although calico coloration occurs in many fancy goldfish varieties such as telescope eyes, fantails, ryukins, orandas, and ranchu's, the nacreous scale characteristic is usually exclusive to the shubunk ...

Tamasaba
The ''Tamasaba'' (玉サバ) or ''Sabao'' is an uncommon Japanese variety of goldfish with a body shape similar to a ''Ryukin'' or a Fantail, but with a long, flowing, single tail that is similar to that of a mackerel, hence its other name, Mackerel Tail. This attractive and strong goldfish variety makes a very suitable pond fish and aquarium fish. Usually white and red tamasaba is rarely seen with other colors. It withstands the cold very well. The ''Tamasaba'' originated from the Yamagata Prefecture in northern Japan Japan is an island country in East Asia. Located in the Pacific Ocean off the northeast coast of the Asia, Asian mainland, it is bordered on the west by the Sea of Japan and extends from the Sea of Okhotsk in the north to the East China Sea ..., hence it is also known as ''Yamagata Kingyō'' or Yamagata Goldfish.Johnson, Erik L., D.V.M. and Richard E.

Dorsal Fin
A dorsal fin is a fin on the back of most marine and freshwater vertebrates. Dorsal fins have evolved independently several times through convergent evolution adapting to marine environments, so the fins are not all homologous. They are found in most fish, in mammals such as whales, and in extinct ancient marine reptiles such as ichthyosaurs. Most have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of whales to identify individuals in the field. The bones or cartilages that support the dorsal fin in fish are called pterygiophores. Functions The main purpose of the dorsal fin is usually to stabilize the animal against rolling and to assist in sudden turns. Some species have further adapted their dorsal fins to other uses. The sunfish uses the dorsal fin (and the anal fin Fins are moving appendages protruding from the body of fish that interact with water to ge ...

Caudal Fin
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bony spines or rays covered by a thin stretch of scaleless skin; in lobe-finned fish (Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central bud supported by jointed bones; in cartilaginous fish (Chondrichthyes) and jawless fish (Agnatha), fins are fleshy " flippers" supported by a cartilaginous skeleton. Fins at different locations of the fish body serve different purposes, and are divided into two groups: the midsagittal ''unpaired fins'' and the more laterally located ''paired fins''. Unpaired fins are predominan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron
Iron is a chemical element; it has symbol Fe () and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most abundant element in the Earth's crust, being mainly deposited by meteorites in its metallic state. Extracting usable metal from iron ores requires kilns or furnaces capable of reaching , about 500 °C (900 °F) higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BC and the use of iron tools and weapons began to displace copper alloys – in some regions, only around 1200 BC. That event is considered the transition from the Bronze Age to the Iron Age. In the modern world, iron alloys, such as steel, stainless steel, cast iron and special steels, are by far the most common industrial metals, due to their mechan ...

Aquarium
An aquarium (: aquariums or aquaria) is a vivarium of any size having at least one transparent side in which aquatic plants or animals are kept and displayed. fishkeeping, Fishkeepers use aquaria to keep fish, invertebrates, amphibians, aquatic reptiles, such as turtles, and aquatic plants. The term ''aquarium'', coined by English naturalist Philip Henry Gosse, combines the Latin root , meaning 'water', with the suffix , meaning 'a place for relating to'. The aquarium principle was fully developed in 1850 by the chemist Robert Warington, who explained that plants added to water in a container would give off enough oxygen to support animals, so long as the numbers of animals did not grow too large. The aquarium craze was launched in early Victorian era, Victorian England by Gosse, who created and stocked the first public aquarium at the London Zoo in 1853, and published the first manual, ''The Aquarium: An Unveiling of the Wonders of the Deep Sea'' in 1854. Small aquariums are k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wakin
The ''Wakin''和�� lit. "Japanese Golden") is an intermediate twin tailed goldfish variety that has been originated from Japan. It is believed the wakin gave rise to fancy twin-tailed goldfish, including the '' ryūkin'', '' ranchū'', '' oranda'', fantail pearlscale, and many more twin-tailed goldfish. It is also the second oldest variety, developed from the common goldfish. In Japan The ''wakin'' has many popular cultures and beliefs in the history of Japanese goldfish. The wakin goldfish, in Japanese terms, are any 'Huna' bodied goldfish with a single tail (in reference to the popular common goldfish), double tail, or triple tail, while in the US, a wakin is simply a double tail goldfish with a long body. They are also seen in red and white, which are prized for competition. Other colors include chocolate, blue, red, white, orange, and yellow. There is also a calico ''wakin'', but for some reason, in regards to its color process, the calico ''wakin'' is not a full-blooded '' ...
