Species
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. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isopoda
Isopoda is an order of crustaceans. Members of this group are called isopods and include both aquatic species and terrestrial species such as woodlice. All have rigid, segmented exoskeletons, two pairs of antennae, seven pairs of jointed limbs on the thorax, and five pairs of branching appendages on the abdomen that are used in respiration. Females brood their young in a pouch under their thorax called the marsupium. Isopods have various feeding methods: some eat dead or decaying plant and animal matter, others are grazers or filter feeders, a few are predators, and some are internal or external parasites, mostly of fish. Aquatic species mostly live on the seabed or the bottom of freshwater bodies of water, but some taxa can swim for short distance. Terrestrial forms move around by crawling and tend to be found in cool, moist places. Some species are able to roll themselves into a ball as a defense mechanism or to conserve moisture like species in the family Armadilli ...

Crustacean
Crustaceans (from Latin meaning: "those with shells" or "crusted ones") are invertebrate animals that constitute one group of arthropods that are traditionally a part of the subphylum Crustacea (), a large, diverse group of mainly aquatic arthropods including decapods (shrimps, prawns, crabs, lobsters and crayfish), seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, opossum shrimps, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods (insects and entognathans) emerged deep in the Crustacean group, with the completed pan-group referred to as Pancrustacea. The three classes Cephalocarida, Branchiopoda and Remipedia are more closely related to the hexapods than they are to any of the other crustaceans ( oligostracans and multicrustaceans). The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bopyridae
The Bopyridae are a family of isopod crustaceans in the suborder Cymothoida. There are 1223 individual species contained in this family. Members of the family are ectoparasites of crab Crabs are decapod crustaceans of the infraorder Brachyura (meaning "short tailed" in Greek language, Greek), which typically have a very short projecting tail-like abdomen#Arthropoda, abdomen, usually hidden entirely under the Thorax (arthropo ...s and shrimp. They live in the gill cavities or under the carapace where they cause a noticeable swelling. Fossil crustaceans have occasionally been observed to have a similar characteristic bulge.

Parasitism
Parasitism is a close relationship between species, where one organism, the parasite, lives (at least some of the time) on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson characterised parasites' way of feeding as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), trophicallytransmitted parasitism (by being eaten), vector-transmitted parasitism, parasitoidism, and micropredation. One major axis of classification concerns invasiveness: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Atergatis Floridus
''Atergatis floridus'', the floral egg crab, green egg crab, pancake crab, or shawl crab, is a species of tropical Indo-Pacific crab from the family Xanthidae. The meat of this crab is toxic, even if cooked, and consumption often results in death. Description ''Atergatis floridus'' has an oval, relatively narrow carapace which has a smooth surface and smooth margins. The carapace is greenish or greenish-blue-brown and is marked with a pattern which resembles lace and is made up of a fine network of fine white or yellow lines white, resembling a shawl. It has large claws which are equal sizes and which are smooth with black spoon-shaped tips and which may be larger in males than females. The pereiopods are squarish in shape and quite thick with lilac edges and lack hair. The width of the carapace is . The carapace is approximately 1.4 times broader than it is long. Distribution ''Atergatis floridus'' occurs in the eastern Indian Ocean from south east Asia, south to Australia whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carpilius Convexus
''Carpilius convexus'', commonly known as the marbled stone crab, is a species of crab found in the Indo-Pacific, from Hawaii to the Red Sea and South Africa. It was first described by Peter Forsskål Peter Forsskål, sometimes spelled Pehr Forsskål, Peter Forskaol, Petrus Forskål or Pehr Forsskåhl (11 January 1732 – 11 July 1763) was a Sweden, Swedish exploration, explorer, oriental studies, orientalist, natural history, naturalist, and ... in 1775 as "''Cancer convexus''", and has sometimes been treated as a variety of the larger species '' Carpilius maculatus''. The biology of the genus ''Carpilius'' is poorly known. The coloration of ''Carpilius convexus'' is a yellow-brown or red, with patches that are mainly brown, growing up to . Despite us knowing their size, coloration, and habitat, little else is known about their biology.

Cymothoida
Cymothoida is a suborder of Isopoda, isopod crustaceans with a mostly Carnivore, carnivorous or Parasite, parasitic lifestyle. It contains more than 2,700 described species in four Taxonomic rank#Ranks in zoology, superfamilies. Members of the suborder are characterised by their specialised mouthparts which include a mandible with a tooth-like process which is adapted for cutting or slicing. Classification Cymothoida contains these superfamilies and families: *Superfamily Anthuroidea Leach, 1814 **Antheluridae Poore & Lew Ton, 1988 **Anthuridae Leach, 1814 **Expanathuridae Poore, 2001 **Hyssuridae Wägele, 1981 **Leptanthuridae Poore, 2001 **Paranthuridae Menzies & Glynn, 1968 *Superfamily Cymothooidea Leach, 1814 **Aegidae White, 1850 **Anuropidae Stebbing, 1893 **Barybrotidae Hansen, 1890 **Cirolanidae Dana, 1852 **Corallanidae Hansen, 1890 **Cymothoidae Leach, 1818 **Gnathiidae Leach, 1814 **Protognathiidae Wägele & Brandt, 1988 **Tridentellidae Bruce, 1984 *Infraorder Epica ...
