Zenopontonia Soror
''Zenopontonia soror'', the starfish shrimp or seastar shrimp, is a species of shrimp in the family Palaemonidae. It is found in shallow water in the tropical Indo-Pacific region. It lives in association with a starfish, often changing its colour to match that of its host. Description ''Zenopontonia soror'' is a medium-sized shrimp growing to a length of about . It has a short, broad rostrum that curves downwards and has ten or eleven teeth on its dorsal surface. It is liberally covered with small white spots, the main colour mimicking that of its host starfish; on '' Linckia laevigata '' it is blue; on ''Acanthaster'' it is two-coloured, bright red with a pale dorsal streak, and on '' Culcita'' it is a less-speckled, clear colour, sometimes with a transparent dorsal streak, blue or maroon, or sometimes white, yellow or pale green. It could be mistaken for the imperial shrimp (''Zenopontonia rex''), but that species uses a sea cucumber or large mollusc as a host. Distribution an ...

Zenopontonia Rex
''Zenopontonia rex'', the emperor shrimp or imperial shrimp, is a species of shrimp in the family Palaemonidae. It is found in shallow water in the tropical Indo-Pacific region. It lives in association with a sea cucumber, a nudibranch or other large mollusc, often changing its colour to match that of its host. Description ''Zenopontonia rex'' is a robust shrimp growing to a length of about , with females being rather larger and slightly less colourful. The antennae are modified into a series of plates that extend forwards from the head, and the rostrum has a crest-like extension. The cephalothorax bears a small spine on either side. The first two pairs of legs bear pincers with short sensory hairs. The basic colour of this shrimp is orange-yellow to orange-red, with purple antennal plates, claws and walking legs. However, during the day, white chromatophores in the skin expand and may cover much of the dorsal surface and tail fan; in other instances, the white colour appears as a ...

Palaemonidae
Palaemonidae is a family of shrimp in the order Decapoda. Many species are carnivores that eat small invertebrates, and can be found in any aquatic habitat except the deep sea. One significant genus is ''Macrobrachium'', which contains commercially fished species. Others inhabit coral reefs, where they associate with certain invertebrates, such as sponges, cnidarians, mollusks, and echinoderms, as cleaner shrimps, parasites, or commensals. They generally feed on detritus, though some are carnivores and hunt tiny animals. The family contains more than 1200 species in 160 genera. The genera were formerly split into two subfamilies, but in 2015, molecular and morphological research determined that the subfamily groupings were invalid. At the same time, the members of the families Gnathophyllidae and Hymenoceridae were incorporated into the Palaemonidae. Genera The following genera are recognised: *'' Actinimenes'' *'' Alburnia'' *'' Allopontonia'' *'' Altopontonia'' *' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceratosoma Trilobatum
''Ceratosoma trilobatum'' is a species of colorful dorid nudibranch, a sea slug, a shell-less marine gastropod mollusk in the family Chromodorididae. Distribution This sea slug was described from India. It is widespread throughout the tropical waters of the Indo-Pacific area, from the oriental African coast to Japan, Red Sea included.Bidgrain, P., 2019''Ceratosoma tenue''Sea Slugs of the Indian Ocean, accessed 2019-01-30. Description ''Ceratosoma trilobatum'' can grow to a maximal size of 15 cm length. The body colouration is extremely variable but is always composed of bright colors. However, the body colouration is not a valuable criterion of determination for this species because it can easily be confused with ''Ceratosoma tenue''. The physical distinctive criteria are two mantle lobes on the first half of the body on each side. The first one is around the head part and the second one is close to the gills. The purple margin of the mantle and foot is an unbroken line. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander James Bruce
Alexander is a male given name. The most prominent bearer of the name is Alexander the Great, the king of the Ancient Greek kingdom of Macedonia who created one of the largest empires in ancient history. Variants listed here are Aleksandar, Aleksander and Aleksandr. Related names and diminutives include Iskandar, Alec, Alek, Alex, Alexandre, Aleks, Aleksa and Sander; feminine forms include Alexandra, Alexandria, and Sasha. Etymology The name ''Alexander'' originates from the (; 'defending men' or 'protector of men'). It is a compound of the verb (; 'to ward off, avert, defend') and the noun (, genitive: , ; meaning 'man'). It is an example of the widespread motif of Greek names expressing "battle-prowess", in this case the ability to withstand or push back an enemy battle line. The earliest attested form of the name, is the Mycenaean Greek feminine anthroponym , , (/Alexandra/), written in the Linear B syllabic script. Alaksandu, alternatively called ''Alakasandu'' or ' ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Shrimp
Shrimp are crustaceans (a form of shellfish) with elongated bodies and a primarily swimming mode of locomotion – most commonly Caridea and Dendrobranchiata of the decapod order, although some crustaceans outside of this order are referred to as "shrimp". More narrow definitions may be restricted to Caridea, to smaller species of either group or to only the marine species. Under a broader definition, ''shrimp'' may be synonymous with prawn, covering stalk-eyed swimming crustaceans with long, narrow muscular tails (abdomens), long whiskers ( antennae), and slender legs. Any small crustacean which resembles a shrimp tends to be called one. They swim forward by paddling with swimmerets on the underside of their abdomens, although their escape response is typically repeated flicks with the tail driving them backwards very quickly. Crabs and lobsters have strong walking legs, whereas shrimp have thin, fragile legs which they use primarily for perching.Rudloe & Rudloe (2009 ...

World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as the ''World List of ...
