C
A hollow normally eroded in a cliff (or vertical rock) with the penetration being greater than the width of the entrance (Hiscock, 1996). +
The surface or body part to which eggs are attached by the parent +
specialist - chaetognaths +
Common in OSPAR Region IV +
Common in OSPAR Region III +
Common in OSPAR Regions II, III, IV +
An organism that obtains metabolic energy from oxidation of inorganic substrates such as sulphur, nitrogen or iron (e.g. some micro-organisms) (Lincoln ''et al.'', 1998). +
composed of chitin, a long-chain polymer of N-acetylglucosamine. It is the chief polysaccharide in fungal cell walls and in the exoskeleton of arthropods (derived form Lawrence, 2005). +
Special feeding cell of sponges +
Swimming is effected by beating of cilia and or flagella; includes the fused cilia of Ctenophores. +
The subzone of the rocky sublittoral below that dominated by algae (the infralittoral), and dominated by animals. No lower limit is defined, but species composition changes below about 40m to 80m depth, depending on depth of the seasonal thermocline. This subzone can be subdivided into the upper circalittoral where foliose algae are present and the lower circalittoral where they are not (see Hiscock, 1985). The term is also used by Glémarec (1973) to refer to two étages of the sediment benthos below the infralittoral: a "coastal circalittoral category with a eurythermal environment of weak seasonal amplitude (less than 10°C) varying slowly" and a "circalittoral category of the open sea with a stenothermal environment" (Hiscock, 1996). +
Typically occurs below 50-70 metres away from the influence of wave action. Aphotic with animal communities in stable or stenothermal and stenohaline conditions. Open sea (Connor et al., 1997). +
1) Sediment particles less than 0.004 mm in size (Wentworth, 1922). 2) A soft very fine-grained sedimentary rock composed primarily of clay-sized particles (Hiscock, 1996). +
Number of eggs laid at one time - in organisms that may lay eggs in one or more batches. +
1) Particle size 0.5 - 4 mm (Hiscock, 1996) +
Sediments composed of gravel and sand; inc. gravel, gravelly sand and sandy gravel (Long, 2006) +
