Please answer the following question: Information: - Latin (Latin: ) is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets. - Doryrhamphus is a genus of pipefishes, one of the two genera colloquially known as flagtail pipefishes and are popular in the aquarium trade. The members of this genus are native to the Indian and Pacific Oceans where they inhabit reef environments. The species in this genus have a maximum length of or less, with "D. janssi" being the only species that surpasses . Most species have a horizontal blue line along their body, and all have a whitish-edged tail that is marked contrastingly with black, red or yellow. - A vivarium (Latin, literally for "place of life"; plural: "vivaria" or "vivariums") is an area, usually enclosed, for keeping and raising animals or plants for observation or research. Often, a portion of the ecosystem for a particular species is simulated on a smaller scale, with controls for environmental conditions. - An aquarium (plural: "aquariums" or "aquaria") is a vivarium of any size having at least one transparent side in which water-dwelling plants or animals are kept and displayed. Fishkeepers use aquaria to keep fish, invertebrates, amphibians, aquatic reptiles such as turtles, and aquatic plants. The term, coined by English naturalist Philip Henry Gosse, combines the Latin root "aqua", meaning water, with the suffix "-arium", meaning "a place for relating to". The aquarium principle was fully developed in 1850 by the chemist Robert Warington, who explained that plants added to water in a container would give off enough oxygen to support animals, so long as their numbers do not grow too large. The aquarium craze was launched in early Victorian England by Gosse, who created and stocked the first public aquarium at the London Zoo in 1853, and published the first manual, "The Aquarium: An Unveiling of the Wonders of the Deep Sea" in 1854. - Seahorse is the name given to 54 species of small marine fishes in the genus Hippocampus. "Hippocampus" comes from the Ancient Greek word "hippos" meaning "horse" and "kampos" meaning "sea monster". The word "seahorse" can also be written as two separate words (sea horse), or hyphenated (sea-horse). Having a head and neck suggestive of a horse, seahorses also feature segmented bony armour, an upright posture and a curled prehensile tail. - Pipefishes or pipe-fishes (Syngnathinae) are a subfamily of small fishes, which, together with the seahorses and seadragons, form the family Syngnathidae. - London Zoo is the world's oldest scientific zoo. It was opened in London on April 27, 1828, and was originally intended to be used as a collection for scientific study. In 1932 the animals of the Tower of London menagerie were transferred to the zoo's collection. It was eventually opened to the public in 1847. Today it houses a collection of 756 species of animals, with 17,480 individuals, making it one of the largest collections in the United Kingdom. The zoo is sometimes called Regent's Zoo. - The Syngnathidae is a family of fish which includes the seahorses, the pipefishes, the pipehorses, and the leafy, ruby, and weedy seadragons. The name is derived from Greek, "syn", meaning "fused" or "together", and "gnathus", meaning "jaws". This fused jaw trait is something the entire family has in common. - Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. - Dunckerocampus is a genus of pipefishes one of two genera known as the flagtail pipefishes. This genus is native to the Indian and Pacific Oceans where they are usually found in reef environments. These species are elongated and have a maximum length between , with "D. chapmani" being the only species with a maximum length below . Their tail is red with a whitish edge, and in some species there is a white or yellow spot in the center. All except "D. baldwini" have vertical red/brown and yellow/white stripes on their body. Species. There are currently seven recognized species in this genus: - A genus (genera) is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. - Invertebrates are animals that neither possess nor develop a vertebral column (commonly known as a "backbone" or "spine"), derived from the notochord. This includes all animals apart from the subphylum Vertebrata. Familiar examples of invertebrates include insects; crabs, lobsters and their kin; snails, clams, octopuses and their kin; starfish, sea-urchins and their kin; and worms. - A fish is any member of a group of organisms that consist of all gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well. However, traditionally fish are rendered obsolete or paraphyletic by excluding the tetrapods (i.e., the amphibians, reptiles, birds and mammals which all descended from within the same ancestry). Because in this manner the term "fish" is defined negatively as a paraphyletic group, it is not considered a formal taxonomic grouping in systematic biology. The traditional term pisces (also ichthyes) is considered a typological, but not a phylogenetic classification. - Doryrhamphus and Dunckerocampus , popularly known as flagtail pipefish , are two genera of fishes in the Syngnathidae family . They are found in warm , relatively shallow waters of the Indo - Pacific , with a single species , D. paulus , in the eastern Pacific . Most of these pipefishes are very colourful , and are fairly popular in the marine aquarium hobby despite requiring special care and not being recommended for beginners . Their habit of flashing the distinctly patterned tails during courtship and other displays have earned them their English popular name . Adults are highly territorial and usually live in pairs . They feed on tiny crustaceans and other small animals , and most species from the genus Doryrhamphus will sometimes act as cleaners . What is the relationship between 'flagtail pipefish' and 'subfamily'?
