Cardisoma Armatum
''Cardisoma armatum'' is a species of terrestrial crab. Names It is sometimes referred to as the (African) rainbow crab, (Nigerian) moon crab, or patriot crab. Adults are sometimes labelled as "soapdish" crabs in the pet industry. This name derives from their aggressive nature as adults and when being shipped to pet stores, they are often packed in soap dishes to prevent them from killing each other. The names moon crab and soapdish crab are sometimes applied to other similar crab species, leading to frequent confusion with other colourful crabs such as the three remaining species of ''Cardisoma'', ''Gecarcinus ruricola'', and '' G. quadratus'' (all except '' C. carnifex'' from the Americas). Distribution ''C. armatum'' originates from coastal regions of western Africa, but it also occurs inland along some deltas (e.g. the Volta River delta), and on islands such as Cape Verde. Description When young, these crabs typically have a blueish/violet carapace, red–colored legs, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
