Ctenocheloides
''Ctenocheloides'' is a genus of ghost shrimp in the family Callianassidae, containing the single species ''Ctenocheloides attenboroughi''. It was described in 2010, and named in honour of the British natural history broadcaster Sir David Attenborough. It is known from a single female specimen collected in shallow water on the north-western coast of Madagascar. Description The genus ''Ctenocheloides'' is known from a single female specimen. The total length of the specimen is , with a carapace long. ''Ctenocheloides'' resembles the genus '' Ctenocheles'', as reflected in the name of the genus, both genera having pectinate (comb-like) fingers to the chelae (claws). ''Ctenocheloides'' differs from ''Ctenocheles'' in having no rostrum, having well-developed eyes, and in having shorter, fatter claws. Distribution The single known specimen of ''Ctenocheloides'' was collected in 2008 from a "large, mud-cemented piece of rubble", dredged from a bay near Hell-Ville, Nosy Bé, in no ...

List Of Things Named After David Attenborough And His Works
This is a list of things named after English broadcaster, biologist, natural historian and author Sir David Attenborough, and his audiovisual works. Buildings * David Attenborough Building in Cambridge, which houses the Cambridge University Museum of Zoology and the Cambridge Conservation Initiative (CCI). Ships * RRS ''Sir David Attenborough'', a British polar research ship; famously involved in the ''Boaty McBoatface'' naming poll controversy. Taxonomy David Attenborough's long trajectory working on nature documentaries and supporting conservation initiatives has made him an inspiration and a popular choice among naturalists to honour him with eponyms when naming newly described organisms. Attenborough himself has said that this is the "biggest of compliments that you could ask from any scientific community." As of 2022, there are more than 50 taxa (genera and species) of organisms that have been named after David Attenborough. Additionally, there is at least one species ...

Axiidea
Axiidea is an infraorder of decapod crustaceans. They are colloquially known as mud shrimp, ghost shrimp, or burrowing shrimp; however, these decapods are only distantly related to true shrimp. Axiidea and Gebiidea are divergent infraoders of the former infraorder Thalassinidea. These infraorders have converged ecologically and morphologically as burrowing forms.Dworschak, Peter C. (2012). ''Treatise on Zoology - Anatomy, Taxonomy, Biology. The Crustacea, Volume 9 Part B''. BRILL. pp. 109–100. . Based on molecular evidence as of 2009, it is now widely believed that these two infraorders represent two distinct lineages separate from one another. Since this is a recent change, much of the literature and research surrounding these infraorders still refers to the Axiidea and Gebiidea in combination as "thalassinidean" for the sake of clarity and reference. This division based on molecular evidence is consistent with the groupings proposed by Robert Gurney in 1938 based on larva ...

David Attenborough
Sir David Frederick Attenborough (; born 8 May 1926) is an English broadcaster, biologist, natural historian and author. He is best known for writing and presenting, in conjunction with the BBC Natural History Unit, the nine natural history documentary series forming the ''Life'' collection, a comprehensive survey of animal and plant life on Earth. Attenborough was a senior manager at the BBC, having served as controller of BBC Two and director of programming for BBC Television in the 1960s and 1970s. First becoming prominent as host of ''Zoo Quest'' in 1954, his filmography as writer, presenter and narrator has spanned eight decades; it includes ''Natural World'', ''Wildlife on One'', the ''Planet Earth'' franchise, ''The Blue Planet'' and its sequel. He is the only person to have won BAFTA Awards in black and white, colour, high-definition, 3D and 4K resolutions. Over his life he has collected dozens of honorary degrees and awards, including 3 Emmy Awards for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.

Rostrum (anatomy)
Rostrum (from Latin ', meaning ''beak'') is a term used in anatomy for a number of phylogenetically unrelated structures in different groups of animals. Invertebrates * In crustaceans, the rostrum is the forward extension of the carapace in front of the eyes. It is generally a rigid structure, but can be connected by a hinged joint, as seen in Leptostraca. * Among insects, the rostrum is the name for the piercing mouthparts of the order Hemiptera as well as those of the snow scorpionflies, among many others. The long snout of weevils is also called a rostrum. * Gastropod molluscs have a rostrum or proboscis. * Cephalopod molluscs have hard beak-like mouthparts referred to as the rostrum.

Crustaceans Described In 2010
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapoda, decapods, ostracoda, seed shrimp, branchiopoda, branchiopods, argulidae, fish lice, krill, remipedes, isopoda, isopods, barnacles, copepods, amphipoda, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the Hexapoda, hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from ''Stygotantulus, Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they ecdysis, moult to grow. They are distinguished from other groups of arthropods, such as insec ...

Endemic Fauna Of Madagascar
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic Decapod Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Alpha Taxonomy
In biology, taxonomy () is the science, scientific study of naming, defining (Circumscription (taxonomy), circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxon, taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain (biology), domain, kingdom (biology), kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class (biology), class, order (biology), order, family (biology), family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biologica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mangrove
A mangrove is a shrub or tree that grows in coastal saline water, saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse, as a result of convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs, and became widely distributed in part due to the plate tectonics, movement of tectonic plates. The oldest known fossils of Nypa fruticans, mangrove palm date to 75 million years ago. Mangroves are salt-tolerant trees, also called halophytes, and are adapted to live in harsh coastal conditions. They contain a complex salt filtration system and a complex root system to cope with saltwater immersion and wave action. They are ad ...

Nosy Bé
Nosy Be (formerly Nossi-bé and Nosse Be) is an island off the northwest coast of Madagascar. Nosy Be is Madagascar's largest and busiest tourist resort. It has an area of , and its population was 109,465 according to the provisional results of the 2018 Census. ''Nosy Be'' means "big island" in the Malagasy language. The island was called Assada during the early colonial era of the 17th century. Nosy Be has been given several nicknames over the centuries, including "Nosy Manitra" (the scented island). History The first human inhabitants of Nosy Be were small bands of Antankarana and Zafinofotsy, before the Sakalava people migrated there and became the most numerous ethnic group on the island. These people were joined later by some Comorians, Indians or Antandroy. Nosy Be made first major appearance in Madagascar's history when King Radama I announced that he intended to conquer the whole west of Madagascar. That plan was eventually achieved in 1837 when the Sakalava Kingdom of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
