F
Shaped like a fan, fanlike (Brusca, 1980). +
Flattened ellipsoid (Olenina ''et al.'', 2006) +
An indication of how far an organism can bend/flex without breaking or suffering damage -
High (>45°) / Low (10 – 45°) / None (<10°) +
A species which exhibits fluctuating densities (either undefined in the literature or otherwise not mentioned in the abundance terms/parameters described here). +
An organism able to propel itself though the air e.g. using wings, such as winged insects, birds +
Seabirds +
Stealing food from other birds in flight +
Description of the source of the organisms nurishment, i.e. what it feeds on +
Seabirds/Wader +
Seabirds/Wader +
A dense stand of large plants in which the upper branches (trees) or laminae (macroalgae) overlap to form a canopy that shades the under story of flora and fauna. +
An organism that forms a large area of close individuals forming a canopy (e.g. trees, large kelps). +
1) 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. (FishBase)
2) Fork length (FL) refers to the length of a fish measured from the tip of the snout to the end of the middle caudal fin rays and is used in fishes in which it is difficult to tell where the vertebral column ends. (Wikipedia)
3) Fork length (FL) can be specified as:<ul><li>Maximum length: Size (in cm) of the largest male/unsexed or female specimen ever caught. (FishBase)<li>Common length: Size (in cm) at which male/unsexed or female specimen(s) are commonly caught or marketed. (FishBase)</ul> +
Free living - little modification +
Eggs spawned into water column +
<0.5 psu +
Shaped like a funnel +
G
Descriptors of the relative size of gametes +
The mean period of time between reproduction by parent generation and the reproduction of the first filial generation (Lincoln ''et al.'', 1998); recorded in years. +
Where the species degrades native genetic resources (by hybridizing with native fauna/flora). +
Specialist - e.g. planktivorous fish such as basking shark +
Where the respiratory organs also power and/or provide a feeding apparatus (muco-cilliary feeding) +
An organism that is able to glide through the air (e.g. using some form of membrane) but cannot propel itself through the air (e.g. flying fish) +
Specialist larval form in some freshwater bivalves, characterized by a bivalve shell, with or with a pair of hooks, and a long adhesive thread or tentacle. It lives as a temporary parasite on the gills or fins of fish. In some species a modified glochidium is termed a 'lasidium' before attachment and a 'haustorium' after attachment (Stachowitsch, 1992). +
Free-swimming four armed (lobed) ciliated larva of Platyhelminthes (see Ruppert & Barnes, 1994). +
Having separate sexes/genders (Barnes ''et al.'', 1993). +
fibrous protein in the mesoglea of sea fans (gorgonians) which forms the stiff skeleton of the colony. +
Appendages bear grasping claws (chelae) - e.g. arthropods, crabs, scorpions +
Vertebrate hands, feat, paws etc designed to grasp food items using claws, talons etc. +
1) Particle size 4 -16 mm. 2) Clean stone or shell gravel including dead maerl (Hiscock, 1996) 3) >80% gravel (Long, 2006). +
Mud with 5-30% gravel (see Long, 2006) +
Sand (50-90%) with gravel (>5%) and mud (see Long, 2006) +
Sand with 5-30% gravel (see Long 2006) +
Feeding on herbage, algae or phytoplankton by consuming the whole plant or the surface growth (Lincoln ''et al.'', 1998) +
Generally mobile consumers of sessile prey (e.g. plants, hydroids) cropping exposed tissues usually without killing the whole individual or colony. +
Animals that rasp benthic algae (or sessile animals, such as bryozoan crusts) from the surface of macroalgal fronds and blades (Hiscock ''et al.'', 1999). +
Animals that rasp benthic algae (or sessile animals, such as bryozoan crusts) from inorganic particles e.g. sand grains (MarLIN; Hiscock ''et al.'', 1999). +
Animals that rasp benthic algae (or sessile animals, such as bryozoan crusts) from the substratum (MarLIN; Hiscock ''et al.'', 1999). +
Living in groups or communities, growing in clusters (Thompson, 1995) - where the organisms actively seek out members of the same species as adult or larvae/juveniles for protection from the environment, predators or for breeding +
Common in OSPAR Regions II, III +
seabirds? +
Deterministic growth or indeterminate growth resulting in single unitary individuals or modular (colonial) organisms. +
(expressed as µm, mm, cm per day/month/year) +
