Marine Aquarium Fish Species
The following list of marine aquarium fish species commonly available in the aquarium trade is not a completely comprehensive list; certain rare specimens may be available commercially but not yet listed here. A brief section on each, with a link to the page about the particular species is provided along with references for further information. Angelfish (large) These large fish are considered to be quite hardy, but because of their size may present a significant challenge to the keeper. They need huge aquariums, up to 180 gallons to house one for its entire lifespan. Two Pomacanthidae, angels might be kept in the same aquarium provided it is a large aquarium, they are properly acclimated as juvenile (organism), juveniles, and they have very different colouring and body shape. However, because all Pomacanthidae, Angelfish have essentially the same diet (nutrition), diet, mixing them is a feat that should be left to only advanced keepers. Most are not reef safe, and a potentia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pomacanthus Maculosus, Toledo Zoo
''Pomacanthus'' is a genus of marine angelfish that is usually found around reefs and coral. Some of the notable places one can see these vari-coloured fish includes the Maldives, Sri Lanka, and Sipidan off the southern coast of Sabah, Malaysia. Generally the patterns and colors of these fish undergo a major transformation from juvenile to adult forms. The juveniles may even appear to be a different species. Species The following 13 species are classified within the genus ''Pomacanthus'': Systematics The genus ''Pomacanthus'' was created in 1802 by the French naturalist Bernard Germain de Lacépède (1756-1825) with the type species In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen ... being designated as ''Chaetodon arcuatus''.

Queen Angelfish
The queen angelfish (''Holacanthus ciliaris''), also known as the blue angelfish, golden angelfish, or yellow angelfish, is a species of marine angelfish found in the western Atlantic Ocean. It is a benthic (ocean floor) warm-water species that lives in coral reefs. It is recognized by its blue and yellow coloration and a distinctive spot or "crown" on its forehead. This crown distinguishes it from the closely related and similar-looking Bermuda blue angelfish ('' Holacanthus bermudensis''), with which it overlaps in range and can interbreed. Adult queen angelfish are selective feeders and primarily eat sponges. Their social structure consists of harems which include one male and up to four females. They live within a territory where the females forage separately and are tended to by the male. Breeding in the species occurs near a full moon. The transparent eggs float in the water until they hatch. Juveniles of the species have different coloration than adults and act as cleaner ...

Fish Anatomy
Fish anatomy is the study of the form or morphology of fish. It can be contrasted with fish physiology, which is the study of how the component parts of fish function together in the living fish. In practice, fish anatomy and fish physiology complement each other, the former dealing with the structure of a fish, its organs or component parts and how they are put together, such as might be observed on the dissecting table or under the microscope, and the latter dealing with how those components function together in living fish. The anatomy of fish is often shaped by the physical characteristics of water, the medium in which fish live. Water is much denser than air, holds a relatively small amount of dissolved oxygen, and absorbs more light than air does. The body of a fish is divided into a head, trunk and tail, although the divisions between the three are not always externally visible. The skeleton, which forms the support structure inside the fish, is either made of cartilage ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holacanthus Bermudensis
''Holacanthus bermudensis'', the blue angelfish or Bermuda blue angelfish, is a species of marine ray-finned fish, a marine angelfish belonging to the family Pomacanthidae. It occurs in the western Atlantic Ocean. Taxonomy ''Holacanthus bermudensis'' was first formally described as ''Holacanthus ciliaris bermudensis'' in 1876 by the American ichthyologist George Brown Goode (1851-1896). The original type specimens from Bermuda, the syntypes, were set aside and replaced by a neotype, which was the holotype of ''Angelichthys isabelita'' which had been described by David Starr Jordan and Cloudsley Louis Ritter with the type locality given as Key West in Florida. This is set out in the Official List of Specific Names in Zoology (ICZN, Opinion 2003). This species frequently hybridises with the sympatric queen angelfish (''Holacanthus ciliaris)''. ''H. isabelita'' was formerly considered to be a separate species but is now regarded as a synonym of ''H. bermudensis''. Description ''Hol ...

Male
Male (symbol: ♂) is the sex of an organism that produces the gamete (sex cell) known as sperm, which fuses with the larger female gamete, or ovum, in the process of fertilization. A male organism cannot reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs. Not all species share a common sex-determination system. In most animals, including humans, sex is determined genetically; however, species such as ''Cymothoa exigua'' change sex depending on the number of females present in the vicinity. In humans, the word ''male'' can also be used to refer to gender in the social sense of gender role or gender identity. Overview The existence of separate sexes has evolved independently at different times and in different lineages, an example ...

Female
Female (Venus symbol, symbol: ♀) is the sex of an organism that produces the large non-motile ovum, ova (egg cells), the type of gamete (sex cell) that fuses with the Sperm, male gamete during sexual reproduction. A female has larger gametes than a male. Females and males are results of the anisogamous reproduction system, wherein gametes are of different sizes, unlike isogamy where they are the same size. The exact mechanism of female gamete evolution remains unknown. In species that have males and females, Sex-determination system, sex-determination may be based on either sex chromosomes, or environmental conditions. Most female mammals, including female humans, have two X chromosomes. Female characteristics vary between different species with some species having pronounced Secondary sex characteristic, secondary female sex characteristics, such as the presence of pronounced mammary glands in mammals. In humans, the word ''female'' can also be used to refer to gender i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
