Pets In this report on tropical fish information you will discover information on why folk keep tropical fish, the background to it and the fish classifying scientific naming convention. Keeping Tropical Fish There are a growing number of people who keep tropical fish in an aquarium as it becomes more popular and the age of these aquarists varies from youngsters to the more senior. Because tropical fish tend to be more colored, there is a better choice for the fish keeper and as they are smaller in size you can keep a lot more of them at home in your aquarium, and due to captive breeding the aquarist does not have to buy them in from their tropical environment. It is unlikely that the fish in your aquarium have the same size, color or physique of the initial fish due to years of ongoing breeding, so for example a checkered dwarf cichlid will not have come Venezuela where it originated, but you can import wild stock when rearing in captivity is not successful. The Naming Convention All aquarium species are known by a common name and some may have several names, all of which may be used by aquarists and pet shops on a day to day basis, which may be helpful, but if you want a spot on identification of the fish then these names are of no use. The basis for the modern scheme of binomial nomenclature, the recognized system of naming species, was constituted by a zoologist from Sweden called Carl Linnaeus who was also a botanist and physician and one of those who led the field in modern ecology. The binomial nomenclature identifies and establishes the relationship between groups of animals and plants and has been utilized for over three hundred and fifty years. Taxonomy is the science of finding, describing and categorizing organisms and it has seven major groupings, Kingdom-Phylum-Division-Class-Order-Family-Genus-Species. However, as its name suggests, the binomial nomenclature process only uses the last two identifiers, the genus and the species names. Although each term in the name is in Latin and it could be known as the ‘Latin name’, biologists have a preference for calling it the ‘scientific name’. As Ichthyology (zoological term for studying fish) moves forward it has happened that now and again fish have been put in a different classification but because the new identification name is not used by everyone, you can sometimes end up with one fish having two scientific names. If there is no actual descriptor of the fish for a known genus then the resulting scientific name is the genus name plus the word species. Yearly, around 250 newly discovered species are assigned scientific names and at the start of 2010 there were over 31,000 species registered with a fish information database. Add up all the fish species in the world and it will outnumber all other vertebrates, meaning amphibians, birds, mammals and reptiles. About the Author: 相关的主题文章:
