C
Organisms that come together in large colonies (100 plus individuals) - often in the same area from season to season - usually for breeding purposes +
Symbiosis (q.v.) in which one species derives benefit from a common food supply, whilst the other species is not adversely affected (Lincoln ''et al.'', 1998). +
A species which is found in relatively moderate to high densities (accounts for non-discrete nature of abundance terms/parameters described here). +
Early larval stage in siphonophores, composed of a floating colony with disc-shaped float, and consists of a hollow sphere with aboral thickening (Stachowitsch, 1992). +
Common in OSPAR Regions II, III, IV +
Cone with a half sphere (Olenina ''et al.'', 2006). +
Where the species preys on native fauna or grazes on native flora. +
Free swimming larval stage, typically with five sub-stages, characterized by excretion through maxillary glands, and progressive increase in number of body segments and posterior appendages (see Stachowitsch, 1992). +
Deposition of sands formed by the breakdown to the skeletons of living organisms +
An organism that moves across, up or down the substratum via movements of its legs, appendages or muscles (e.g. ''Carcinus''). +
A narrow crack in hard substratum where penetration is deeper than the width at the entrance; a crevice is <10 mm wide at the entrance, while a fissure is >10 mm (Hiscock ,1996) +
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. +
Forming or resembling a crust (Thompson, 1995) that is solid or resistant to touch or pressure e.g. encrusting coralline algae or sea mats such as ''Umbonula littoralis''. +
Forming or resembling a crust (Thompson, 1995) that yields to the touch or pressure e.g. the gelatinous colonies of ''Botryllus schlosseri'' or soft cushions of sponges such as ''Halichondria'' sp. +
