Caulerpa Ambigua
''Caulerpa ambigua'' is a species of seaweed in the ''Caulerpaceae'' family found in marine waters of the Pacific Ocean near the southern end of Japan. It has a limited distribution and is endemic around the Bonin Islands around south of Japan. Description It has dwarf filiform (threadlike) fronds that are typically in length and only wide, tapering slightly along the length. The branches are arranged in a divaricate pattern and each branch is loosely closed with oppositely arranged scales called ramenta. It is similar in appearance to '' Caulerpa okamurai'' which has a larger spread of distribution. Taxonomy ''Caulerpa ambigua'' was first formally described by Kintarô Okamura in 1897 as part of the work ''On the Algae from Ogasawara-jima (Bonin Islands)'' as published in ''Botanical Magazine, Tokyo''. The specific epithet is taken from the Latin Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin ...

He is the author of important studies about seaweed Seaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. The term includes some types of ''Rhodophyta'' (red), '' Phaeophyta'' (brown) and ''Chlorophyta'' (green) macroalgae. Seaweed species such as ...s.

Japan
Japan is an island country in East Asia. Located in the Pacific Ocean off the northeast coast of the Asia, Asian mainland, it is bordered on the west by the Sea of Japan and extends from the Sea of Okhotsk in the north to the East China Sea in the south.

National University Of Ireland
The National University of Ireland (NUI) () is a federal university system of ''constituent universities'' (previously called '' constituent colleges'') and ''recognised colleges'' set up under the Irish Universities Act 1908, and significantly amended by the Universities Act, 1997. The constituent universities are for all essential purposes independent universities, except that the degrees and diplomas are those of the National University of Ireland with its seat in Dublin. In post-nominals, the abbreviation ''NUI'' is used for degrees from all the constituent universities of the National University of Ireland. History Queen's Colleges at Belfast, Cork, and Galway were established in 1845. In 1849 teaching commenced and a year later they were united under the Queen's University of Ireland. The Catholic University of Ireland was created as an independent university on 3 November 1854 for the education of Catholics; that university was not a recognised university ...

Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Bonin Islands
The Bonin Islands, also known as the , is a list of islands of Japan, Japanese archipelago of over 30 subtropical and Island#Tropical islands, tropical islands located around SSE of Tokyo and northwest of Guam. The group as a whole has a total area of but only two of the islands are permanently inhabited, Chichijima and Hahajima. Together, their population was 2,560 as of 2021. Administratively, Tokyo Metropolitan Government, Tokyo's Ogasawara Subprefecture also includes the settlements on the Volcano Islands and the Japan Maritime Self-Defense Force, Self-Defense Force post on Iwo Jima. The seat of government is Chichijima. Because of the Bonins' isolation, many of their animals and plants have undergone unique evolutionary processes. It has been called "the Galápagos Islands, Galápagos of the Orient" and was named a natural World Heritage Site in 2011. When first reached during the early modern period, the islands were entirely uninhabited. Subsequent research has found ev ...

Divaricate
Divaricate means branching, or having separation or a degree of separation. The angle between branches is wide. In botany In botany, the term is often used to describe the branching pattern of plants. Plants are said to be divaricating when their growth form is such that each internode diverges widely from the previous internode, producing an often tightly interlaced shrub or small tree. Of the 72 small leaved shrubs found on the Banks Peninsula, for example, some 38 are divaricating. See also * Diastasis (pathology) In pathology, diastasis is the separation of parts of the body that are normally joined, such as the separation of certain abdominal muscles during pregnancy, or of adjacent bones without fracture.

Caulerpa Okamurai
''Caulerpa'' is a genus of seaweeds in the family Caulerpaceae (among the green algae). They are unusual because they consist of only one cell with many nuclei, making them among the biggest single cells in the world. Referring to the crawling habit of its thallus, the name means 'stem (that) creeps', from the Ancient Greek ' (, ‘stalk’) and ' (, ‘to creep’). Taxonomy and nomenclature First described by Jean Vincent Lamouroux in 1809, ''Caulerpa'' is the only genus under the family Caulerpaceae, from the order Bryopsidales, class Ulvophyceae, and phylum Chlorophyta. Through the use of ''tuf''A gene sequencing, it was revealed that ''Pseudochlorodesmis'' F. Børgesen was a sister clade of ''Caulerpa''. Cremen et al. proposed a new classification scheme in Bryopsidales, wherein Caulerpaceae and Halimedaceae were described as sister families. Species discrimination via morphology-based identification is often hampered by the high degree of variation among traits. Thus, s ...

Botanical Name
A botanical name is a formal scientific name conforming to the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or cultivar group, Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, Fungus, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), Chytridiomycota, chytrids, oomycetes, slime moulds and Photosynthesis, photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated variou ...
