Understanding the Scientific Names of Marine Aquarium Inhabitants

Scientific names are the nomenclature of living beings to establish their unique, universal identity, agreed as per the international standards. They are helpful in easily identifying even exotic lives, which may have varied & multiple local names in different regions. Therefore, to avoid any confusion among similar fishes, it is always better to know their scientific name. Understanding the origin of a fish enables you to remember its name without much difficulty.

Phylogeny or Taxonomy is the branch of science dealing with biological classification. The technique adopted is similar to a family tree, which shows how each member of a category is related to the other. At the naming level, living organisms are classified into genus and species. Genus mostly specify the broad category, while species go specific, based on the attributes, including color, spots, stripes, breeding type, personal name, native name, and location of collection. First part of the scientific name is Genus and is represented with first Cap, while the second part is Species, reflected in all small. For example, in Chaaetopyge melanosa, Chaaetopyge is Genus and melanosa is species.

Phylogeny is effective for aquarists to understand fish names. The right identification of your water pet enables you to arrange for better water conditions, appropriate food, and safe breeding. Here are some broad categories to recognize different marine animals.
