Rhynchocinetidae
The family Rhynchocinetidae are a group of small, reclusive red-and-white shrimp. This family typically has an upward-hinged foldable rostrum, hence its taxon name ''Rhynchocinetidae'', which means ''movable beak''; this gives these shrimps their common name of hinge-beak shrimps. The family contains only two genera, '' Cinetorhynchus'' and '' Rhynchocinetes''. Taxonomy Rhynchocinetidae has historically been considered to include the single genus ''Rhynchocinetes'', which was subdivided into two sub-genera. However, in 1995, Holthuis elevated the subgenus ''Cinetorhynchus'' to full generic status based on morphology. Members of ''Rhynchocinetes'' have two acute teeth on the central carina of the carapace, a supraorbital spine and no spine on the margins of the fourth and fifth abdominal somites. ''Cinetorhynchus'' differs in having three teeth on the carapace, no supraorbital spine and a single spine each on the margins of the fourth and fifth abdominal somites. Description Mem ...

Caridea
The Caridea, commonly known as caridean shrimp or true shrimp, are an infraorder of shrimp within the order Decapoda. This infraorder contains all species of true shrimp. They are found widely around the world in both fresh and salt water. Many other animals with similar names – such as the mud shrimp of Axiidea and the boxer shrimp of Stenopodidea – are not true shrimp, but many have evolved features similar to true shrimp. Biology Carideans are found in every kind of aquatic habitat, with the majority of species being marine. Around a quarter of the described species are found in fresh water, however, including almost all the members of the species-rich family Atyidae and the Palaemonidae subfamily Palaemoninae. They include several commercially important species, such as ''Macrobrachium rosenbergii'', and are found on every continent except Antarctica. The marine species are found at depths to , and from the tropics to the polar regions. In addition to the great variety in ...

Cinetorhynchus
''Cinetorhynchus'' is a genus of shrimp in the family Rhynchocinetidae. It was originally described in 1995 by Lipke Holthuis as a subgenus In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between t ... of the genus '' Rhynchocinetes'', but was elevated to the rank of genus by Okuno in 1997. Both genera share the characteristic jointed rostrum, but differ in the numbers and positions of various spines.

Cinetorhynchus Rigens
''Cinetorhynchus rigens'' is a species of shrimp in the family Rhynchocinetidae. Common names include mechanical shrimp, Atlantic dancing shrimp, red night shrimp and red coral shrimp. It occurs in shallow water in the tropical Atlantic Ocean. Description Like other members of its family, ''Cinetorhynchus rigens'' has an upward-hinging, foldable rostrum. The body is robust, especially the cephalothorax, with a length of up to . The rostrum has three large and two small teeth dorsally and eight or nine teeth ventrally. The eyes are particularly noticeable, the corneas being rounded and much larger than the eyestalks. The third abdominal segment is prominently humped. The first pair of walking legs are tipped with pincers and the other walking legs are more slender. The general colour of this shrimp is red and white, the rostrum being white with a patchwork of red blotches, the abdomen transversely striped with red and white and the legs banded in the same colours.

Arnold Edward Ortmann
Arnold Edward Ortmann (April 8, 1863 – January 3, 1927) was a Prussian-born United States naturalist and zoologist who specialized in malacology. Biography Ortmann was born in Magdeburg, Prussia on April 8, 1863. A student of Ernst Haeckel, he graduated from the University of Jena in 1885 with a Ph.D.; he had also studied at the University of Kiel and the University of Strasbourg. From 1886 on, he worked as an instructor at the University of Strasbourg. Together with Haeckel, he participated in an expedition to Zanzibar in 1890/91. Three years later, he emigrated to the United States, where he got a post as the curator of the department of invertebrate paleontology at Princeton University. In 1899, he participated in the Peary Relief expedition, and one year later, he was naturalized as a U.S. citizen. In 1903, he moved to Pittsburgh. He became the curator of invertebrate zoology at the Carnegie Museum and from 1910 on, he was professor of physical geography at the Univers ...

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 ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

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.

Australian Faunal Directory
The Australian Faunal Directory (AFD) is an online catalogue of taxonomic and biological information on all animal species known to occur within Australia. It is a program of the Department of Climate Change, Energy, the Environment and Water of the Government of Australia. By May 12, 2021, the Australian Faunal Directory has collected information about 126,442 species and subspecies In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species .... It includes the data from the discontinued ''Zoological Catalogue of Australia'' and is regularly updated. Started in the 1980s, it set a goal to compile a "list of all Australian fauna including terrestrial vertebrates, ants and marine fauna" and create an "Australian biotaxonomic information system".''Commonwealth Record'', Volume 5, Issues 26-34, p. 1 ...

Carapace
A carapace is a Dorsum (biology), dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron. Crustaceans In crustaceans, the carapace functions as a protective cover over the cephalothorax (i.e., the fused head and thorax, as distinct from the abdomen behind). Where it projects forward beyond the eyes, this projection is called a rostrum (anatomy), rostrum. The carapace is Calcification, calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and Isopoda, isopods, but isopods only have a developed "cephalic shield" carapace covering the head. Arachnids In arachnids, the carapace is formed by the fusion of prosomal tergites into a single Plate (animal anatomy), plate which carries the e ...

Predation
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate and inv ...
