1) Coasts which face the prevailing wind but which have a degree of shelter because of extensive shallow areas offshore, offshore obstructions, or a restricted (less than 90°) window to open water. These sites are not generally exposed to large waves or regular swell. 2) Open coasts facing away from prevailing winds but with a long fetch, and where strong winds are frequent. +
Common in OSPAR Regions II, III, IV +
Egg/sperm meet and fertilize externally to parental individuals, tissues or confines of their bodies, but within the fluid medium +
A built-structure inhabited by an organism and essential to its survival, but not part of its body, composed of hardened (either rigid or flexible) secretions, with or without the addition of embedded particles, with those particles either selectively collected from the environment or passively becoming glued during formation (pers. comm. Read, G.). +
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. +
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. +
Species that were present but have been declared extinct. +
Open coastlines which face into the prevailing wind and receive both wind-driven waves and oceanic swell without any offshore obstructions such as islands or shallows for several thousand kilometres and where deep water is close to the shore (50 m depth contour within about 300 m). +
Fully enclosed coasts with a fetch of no more than about 3 km. +

The FAO Fisheries and Aquaculture Statistics and Information Branch (FIAS) collates world capture and aquaculture production statistics at either the species, genus, family or higher taxonomic levels in 2 346 statistical categories (2019 data release) referred to as species items.
ASFIS list of species includes 12 771 species items selected according to their interest or relation to fisheries and aquaculture. For each species item stored in a record, codes (ISSCAAP group, taxonomic and 3-alpha) and taxonomic information (scientific name, author(s), family, and higher taxonomic classification) are provided. An English name is available for most of the records, and about one third of them have also a French and Spanish name. Information is also provided about the availability of fishery production statistics on the species item in the FAO databases. +
Dense aggregation of animals that visually dominate the seabed or shore such as brittlestars (e.g. ''Ophiothrix fragilis'' ) or mussels (e.g. ''Mytilus edulis''). +
Descriptors of types of unusual or unique types of substratum or habitat +
Traits related to how an organism feeds, the food type and feeding method exhibited by a species +
Description of the apparatus (mechanism) used to collect/capture food +
A description of how the oganism gathers food, and from where +
Description of the location of fertilization, whereby in animals/macroalgae a gametes are fertilized or in plants pollination occurs. +
Specialist e.g. sea squirts +
Particle size 0.063 - 0.5 mm (Hiscock, 1996) +
