A
Species that were reported at some time to be present but were not recorded subsequently are reported to be ‘Absent’. +
Abundance and population trends of species populations have been recorded where this information was available. +
Common in OSPAR Regions II, III, IV +
Occupying the ocean floor from ca 4000 - 6000 m depth. Usually a more or less flat plain (Lincoln ''et al.'', 1998). +
Overlays the plains of the major ocean basins with a lower boundary of ca 6000 m. +
Other structures such as palps, tentacles or a radiolar crown ("grooved palps"). There are forms of single pair of grooved palps nearly always attached dorsally or near the junction of the prostomium and peristomium, or multiple grooved palps sometimes forming a crown. Dorso lateral ciliated folds in the roof of the buccal cavity may be present in some polychaetes. +
An organism that constructs reefs or raised beds of accreted materials, e.g. bound sand in ''Sabellaria'' spp. +
The reproductively capable (mature), fully formed, usually longest lived, stage of an animals life cycle. +
Eggs are placed or retained within the parents burrow +
Where the species physically alters the nature of the strata/habitat. +
Age recorded in days, months, years. +
An organism that constructs reefs and raised beds due to aggregation of large numbers of individuals via permanent or semi-permanent attachment e.g. mussels, oysters and ''Crepidula'' beds. +
Constructs deep beds of calcareous algal nodules, e.g. maerl beds +
36-40 psu +
