standard length (SL) | The measurement from the most anterior tip of the body to the midlateral posterior edge of the hypural plate (in fish with a hypural plate) or to the posterior end of the vertebral column (in fish lacking hypural plates). It may be restricted to the tip of the snout if the lower jaw projects. The base of the caudal fin (end of the vertebral column or posterior edge of the hypural plate) is determined by flexing the tail up while the caudal peduncle is held down. The resultant wrinkle or caudal flexure indicates the caudal base. It may also be determined by probing or dissection. Sometimes the posteriormost point is the last scale, the last pored scale or the beginning of the caudal fin rays. It is the usual scientific measurement for length of a fish except in Myxini, Petromyzontiformes, Elasmobranchii and Holocephali. This measurement is used because long-preserved fish often lose the tips of the caudal fin rays through breakage after the desiccation effect of alcohol. See total length and fork length. In Holocephali the length is usually taken from the tip of the snout to the origin of the upper caudal fin because the caudal filament breaks off frequently. In Scaridae it is taken back to the rear margin of the second to last lateral line scale {because the large scales obscure the point of caudal flexure. In small dead fish, the end point is detected by bending the caudal fin to one side. In fishery work, as a result of the use of the measuring board, standard-, fork- and total length are taken from the most anterior part of the head. Abbreviated as SL. | 1128 |
total length (TL) | The greatest length of the whole body between the most anterior point of the body and the most posterior point, in a straight line, not over the curve of the body. Sometimes, when there are two equal lobes, the caudal rays are squeezed together and their tip is taken as the most posterior point (excluding the caudal filaments), or the longest lobe is squeezed to the midline (maximum length or extreme tip length). Also an imaginary line may be drawn between the two lobe tips and length to its mid-point taken as the most posterior point (total auxiliary length or bilobular length). Usually the tip of the most posterior lobe of the fin in normal position is taken as the posteriormost point (total normal length or natural tip length). Total length is used by taxonomists in Myxini, Petromyzontiformes, usually in Elasmobranchii and sometimes in other fishes. Standard length is usually employed with Teleostei. Abbreviated TL. | 1128 |
fork length (FL) | Length of a fish measured from the tip of the snout to the posterior end of the middle caudal rays. This measurement is used instead of standard length for fishes on which it is difficult to ascertain the end of the vertebral column, and instead of total length in fish with stiff, forked tail, e.g., tuna. Mostly used in fishery biology and not in systematics. | 1128 |
width of disk (WD) | The greatest distance between the lateral tips of the pectoral fins in Rajiformes. | 1128 |

+ Development | Description of how organisms develop into adults. | |
direct development | Type of heterochronous development in which the embryo abandons the larval stages of development and proceeds directly to adult stage (Henderson's Dictionary of Biology; Lawrence, 2005). Animals (including humans) whose young are essentially smaller, less sexually mature, versions of the adult are referred to as direct developers (Gilbert & Bareesi, 2016). The embryos of directly developing organisms generate at once a juvenile already possessing the complete adult body plan, which then grows and acquires sexual maturity (Arenas-Mena, 2010). | 424973 |
indirect development | Most animal species are indirect developers whose life cycle includes a larval stage with characteristics very different from those of the adult organism, which emerges only after a period of metamorphosis (Gilbert & Barresi, 2016).

parasitic | Any organism that is intimately associated with, and metabolically dependent upon another living organism (the host) for completion of its life cycle, and which is typically detrimental to the host to a greater or lesser extent. | 416344 |
ectoparasitic | A parasite that lives on the outer surface of its host, ectosite; epiparasite; episite; exoparasite; cf. endoparasite. | 416344 |
endocommensal | A commensal symbiont that lives inside of its host. | 416344 |
endoparasitic | An internal parasite which lives within the organs or tissues of its host; endosite; entoparasite; cf. ectoparasite. | 416344 |
predator | Any organism that feeds by preying on other organisms, killing them for food. | 416344 |
on sessile prey | Any organism that feeds by preying on sessile organisms, killing them for food (adapted from Lincoln et al., 1998). | 416344 |
on mobile prey | Any organism that feeds by preying on mobile organisms, killing them for food (adapted from Lincoln et al., 1998). | 416344 |
predator/omnivore | Feeding group category for marine free-living meiobenthic Nematoda. Group 2-B: With big and powerful armature of different structure. Mostly predators. Prey swallowed whole or pierced by means of spears or teeth and the liquid food sucked and swallowed. | 181619 |
scavenger | Any organism that feeds on carrion or organic refuse. | 416344 |
suspension feeder | Any organism that feeds on particulate organic matter suspended in water. | 416344 |
facultative | Facultative suspension feeder. Some species (e.g. polychaetes Nereis diversicolor and Pygospio elegans, gastropods Valvata piscinalis and Viviparus viviparus, bivalve Macoma balthica, etc) are known to use more than one feeding mode, e.g. to get particles from the water column (by filtering or using mucus nets) and also collect detritus from the surface of the bottom sediments (Fauchald and Jumars 1979; Kuznetzov 1980; Tsikhon-Lukanina 1987). These species were defined as “facultative suspension-feeders” to distinguish them from those which exclusively suspension-feed, i.e. “obligatory suspension-feeders”, such as the bivalve Mytilus edulis trossulus, the barnacle Balanus improvisus or the bryozoan Electra crustulenta. | 424854 |
symbiotic | Participating in symbiosis. Symbiosis is the living together of two organisms; the relationship between two interacting organisms or populations, commonly used to describe all relationships between members of two different species, and also to include intraspecific associations; sometimes restricted to those associations that are mutually beneficial. | 416344 |
epizoic | 1: Living attached to the body of an animal; used of a non-parasitic animal that lives attached to the outer surface of another animal; epizoan, epizoism, epizoite, epizoon; cf. endozoic. 2: Dispersed by attachment to the surface of an animal; epizoochorous. | 416344 |

Extinct | A taxon is Extinct when there is no reasonable doubt that the last individual has died. A taxon is presumed Extinct when exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal, annual), throughout its historic range have failed to record an individual. Surveys should be over a time frame appropriate to the taxon's life cycle and life form. | 421683 |
Extinct in the Wild | A taxon is Extinct in the Wild when it is known only to survive in cultivation, in captivity or as a naturalized population (or populations) well outside the past range. A taxon is presumed Extinct in the Wild when exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal, annual), throughout its historic range have failed to record an individual. Surveys should be over a time frame appropriate to the taxon's life cycle and life form. | 421683 |
Critically Endangered | A taxon is Critically Endangered when the best available evidence indicates that it meets any of the criteria A to E for Critically Endangered (see Section V), and it is therefore considered to be facing an extremely high risk of extinction in the wild. | 421683 |
Endangered | A taxon is Endangered when the best available evidence indicates that it meets any of the criteria A to E for Endangered (see Section V), and it is therefore considered to be facing a very high risk of extinction in the wild. | 421683 |
Vulnerable | A taxon is Vulnerable when the best available evidence indicates that it meets any of the criteria A to E for Vulnerable (see Section V), and it is therefore considered to be facing a high risk of extinction in the wild. | 421683 |
Conservation Dependent | Taxa which are the focus of a continuing taxon-specific or habitat-specific conservation programme targeted towards the taxon in question, the cessation of which would result in the taxon qualifying for one of the threatened categories above within a period of five years. (Note: The conservation dependent category is part of the IUCN 1994 Categories & Criteria (version 2.3), which is no longer used in evaluation of taxa, but persists in the IUCN Red List for taxa evaluated prior to 2001, when version 3.1 was first used. Using the 2001 (v3.1) system these taxa are classed as near threatened, but those that have not been re-evaluated remain with the "conservation dependent" category.) | 421687 |
Near Threatened | A taxon is Near Threatened when it has been evaluated against the criteria but does not qualify for Critically Endangered, Endangered or Vulnerable now, but is close to qualifying for or is likely to qualify for a threatened category in the near future. | 421683 |
Least Concern | A taxon is Least Concern when it has been evaluated against the criteria and does not qualify for Critically Endangered, Endangered, Vulnerable or Near Threatened. Widespread and abundant taxa are included in this category. | 421683 |
Data Deficient | A taxon is Data Deficient when there is inadequate information to make a direct, or indirect, assessment of its risk of extinction based on its distribution and/or population status. A taxon in this category may be well studied, and its biology well known, but appropriate data on abundance and/or distribution are lacking. Data Deficient is therefore not a category of threat. Listing of taxa in this category indicates that more information is required and acknowledges the possibility that future research will show that threatened classification is appropriate. It is important to make positive use of whatever data are available. In many cases great care should be exercised in choosing between DD and a threatened status. If the range of a taxon is suspected to be relatively circumscribed, and a considerable period of time has elapsed since the last record of the taxon, threatened status may well be justified. | 421683 |

OSPAR Region I (Arctic Waters) | Region I is the most northerly OSPAR region, characterised by its harsh climate and ice coverage although the ecosystems of this region are still rich. In spite of its low population density, human activities such as fishing and offshore petroleum production remain significant. (https://www.ospar.org/convention/the-north-east-atlantic/i) | 197508 |
OSPAR Region II (Greater North Sea) | The Greater North Sea is one of the busiest maritime areas. Offshore activities related to the exploitation of oil and gas reserves, and maritime traffic are very important. Two of the world's largest ports are situated on the North Sea coast, and the coastal zone is used intensively for recreation. (https://www.ospar.org/convention/the-north-east-atlantic/ii) | 197508 |
OSPAR Region III (Celtic Seas) | The Celtic Seas region contains wide variations in coastal topography, from fjordic sea lochs, to sand dunes, bays, estuaries and numerous sandy beaches. The large range of habitats in the region supports a diverse fish fauna. Although traditional maritime activities, such as fishing, take place in the Celtic Seas, there is ongoing development of tourism. (https://www.ospar.org/convention/the-north-east-atlantic/iii) | 197508 |
OSPAR Region IV (Bay of Biscay/Golfe de Gascogne & Iberian coasts) | The bottom topography of Region IV and coastlines are highly diversified, including the continental shelf and slope and parts of the abyssal plain. Ecosystems in Region IV are very rich, support a rich fish fauna and have a particular importance for migratory birds. Main human activities in Region IV are fishing, maritime transport and tourism. (https://www.ospar.org/convention/the-north-east-atlantic/iv) | 197508 |
OSPAR Region V (Wider Atlantic) | Region V represents the deep waters of the North-East Atlantic extending across the abyssal plain and the Mid-Atlantic Ridge, and including many seamounts. There have been recent discoveries of a number of different fragile deep-sea habitats (such as hydrothermal vents, carbonate mounds, coral gardens and sponge communities). Human population in the region is restricted to the Azores Archipelago. The main human activities are fishing and maritime transport.

Pelagic zones | | |
Epipelagic zone (0-200 m) | The depth zone of the water column extending from the surface to 200 m. Because this zone has sufficient light penetration for photosynthesis, it is sometimes referred to as the photic zone. | |

It is important to note that there is no single definition for the littoral zone because its full extent and divisions vary in different contexts and sources. The littoral zone includes the intertidal, but also all neritic waters within the bounds of the continental shelves. Although the littoral zone is larger than the intertidal zone, littoral and intertidal are often used interchangeably. The part of the shore covering the intertidal and the splash zone, with the upper limit marked by the top of the lichen zone and the lower limit marked by the top of the laminarian kelp zone.

This zone is also referred to as the mediolittoral zone, midlittoral zone or the intertidal zone. Allhough the intertidal zone is part of the littoral zone, littoral and intertidal are often used interchangeably (see definition for Littoral zone). | |
Sublittoral zone/Subtidal zone | The sublittoral zone comprises the seafloor from the low tide mark to the edge of the continental shelf, typically down to 200 m deep. The shallowest portion of the sublittoral zone is sometimes referred to as the subtidal zone. Allthough the sublitoral zone is larger than the subtidal zone, sublittoral and subtidal are often used interchangeably. The part of the shore continuously covered by water, below the intertidal zone. (Definition composed by Line Le Gall, Olivier De Clerck, Sofie Vranken and Marine Robuchon, based on diverse literature sources, in the framework of compiling macroalgae traits.)
