Promachocrinus Fragarius
''Promachocrinus fragarius'', commonly known as the Antarctic strawberry feather star, is a species of stemless, free-swimming crinoid. It was one of several new species of ''Promachocrinus'' to be described in 2023. The discovery of the species gained significant media attention. Description The team which discovered the species said it was dubbed the 'Antarctic strawberry feather star' due to "the resemblance of its body to a strawberry". Its colour can range from "purple" to "dark-reddish", and it was described as having "ten rays" and "twenty arms". Distribution and habitat ''P. fragarius'' is found in the waters of Antarctica at depths between and . The type locality is at the South Sandwich Islands The South Sandwich Islands () are a chain of uninhabited volcanic islands in the South Atlantic Ocean. They are administered as part of the British Overseas Territory of South Georgia and the South Sandwich Islands. The chain lies in the sub-A .... The dispersal of ''Pro ...

Crinoid
Crinoids are marine invertebrates that make up the class Crinoidea. Crinoids that remain attached to the sea floor by a stalk in their adult form are commonly called sea lilies, while the unstalked forms, called feather stars or comatulids, are members of the largest crinoid order, Comatulida. Crinoids are echinoderms in the phylum Echinodermata, which also includes the starfish, brittle stars, sea urchins and sea cucumbers. They live in both shallow water and in depths of over . Adult crinoids are characterised by having the mouth located on the upper surface. This is surrounded by feeding arms, and is linked to a U-shaped gut, with the anus being located on the oral disc near the mouth. Although the basic echinoderm pattern of fivefold symmetry can be recognised, in most crinoids the five arms are subdivided into ten or more. These have feathery pinnules and are spread wide to gather planktonic particles from the water. At some stage in their lives, most crinoids have a sho ...

Strawberry
The garden strawberry (or simply strawberry; ''Fragaria × ananassa'') is a widely grown Hybrid (biology), hybrid plant cultivated worldwide for its fruit. The genus ''Fragaria'', the strawberries, is in the rose family, Rosaceae. The fruit is appreciated for its aroma, bright red colour, juicy texture, and sweetness. It is eaten either fresh or in prepared foods such as fruit preserves, jam, ice cream, and chocolates. Artificial strawberry flavourings and aromas are widely used in commercial products. Botanically, the strawberry is not a berry (botany), berry, but an aggregate fruit, aggregate accessory fruit, accessory fruit. Each apparent 'seed' on the outside of the strawberry is actually an achene, a botanical fruit with a seed inside it. The garden strawberry was first bred in Brittany, France, in the 1750s via a cross of ''Virginia strawberry, F. virginiana'' from eastern North America and ''Fragaria chiloensis, F. chiloensis'', which was brought from Chile by Amédé ...

Type Locality (biology)
In biology, a type is a particular wikt:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the ...

South Sandwich Islands
The South Sandwich Islands () are a chain of uninhabited volcanic islands in the South Atlantic Ocean. They are administered as part of the British Overseas Territory of South Georgia and the South Sandwich Islands. The chain lies in the sub-Antarctic region, about southeast of South Georgia and northeast from the tip of the Antarctic Peninsula. The archipelago comprises 11 main islands forming an island arc running north–south, the largest being Montagu at . It is divided into four groups, from north to south: The Traversay, Candlemas and Central Islands ( Saunders, Montagu, and Bristol), and Southern Thule. The archipelago is prone to violent earthquakes. Over the previous century, nine M 7+ earthquakes have occurred here, the most recent being the M 8.1 in August 2021. None of these earthquakes are known to have caused fatalities due to their remote location. History The southern eight islands of the South Sandwich Islands were discovered by Captain ...

ZooBank
ZooBank is an open access website intended to be the official International Commission on Zoological Nomenclature (ICZN) registry of zoological nomenclature. Any nomenclatural acts (e.g. publications that create or change a taxonomic name) published electronically need to be registered with ZooBank prior to publication to be "officially" recognized by the ICZN Code of Nomenclature. Acts published in physical publications are encouraged, but not required to be registered prior to their publication. Life Science Identifiers (LSIDs) are used as the globally unique identifier for ZooBank registration entries. The ZooBank prototype was seeded with data from Index to Organism Names (http://www.organismnames.com), which was compiled from the scientific literature in ''Zoological Record'' now owned by Thomson Reuters. History ZooBank was officially proposed in 2005 by the executive secretary of ICZN. The registry was live on 10 August 2006 with 1.5 million species entered. The fir ...
