T
The measure of body size specific to a taxonomic group. +
Fish measurement is the measuring of the length of individual fish and of various parts of their anatomy. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. (Wikipedia) +
An organism that can temporarily attach to a substratum but is able to release its attachment, and move across (or through) it (i.e. sedentary) (e.g. ''Actinia''). +
A slender, flexible limb or appendage in an animal, especially around the mouth of an invertebrate, used for grasping or moving about, or bearing sense organs (OED). +
Independent but maintains a defined territory +
The horizontal movement of water associated with the meteorological, oceanographical and topographical factors. High water flow rates result in areas where water is forced through or over restrictions for example narrows or around protruding offshore rocks. Tidal streams are associated with the rise and fall of the tide where as currents are defined as residual flow after the tidal element is removed (Hiscock, 1996). +
1) The greatest length of the whole body between the most anterior point of the body and the most posterior point, in a straight line, not over the curve of the body. Sometimes, when there are two equal lobes, the caudal rays are squeezed together and their tip is taken as the most posterior point (excluding the caudal filaments), or the longest lobe is squeezed to the midline (maximum length or extreme tip length). Also an imaginary line may be drawn between the two lobe tips and length to its mid-point taken as the most posterior point (total auxiliary length or bilobular length). Usually the tip of the most posterior lobe of the fin in normal position is taken as the posteriormost point (total normal length or natural tip length). Total length is used by taxonomists in Myxini, Petromyzontiformes, usually in Elasmobranchii and sometimes in other fishes. Standard length is usually employed with Teleostei. Abbreviated TL. (FishBase)
2) Total length (TL) refers to the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. (Wikipedia)
Total length measurements are used in slot limit and minimum landing size regulations. (Wikipedia)
3) Total length (TL) 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> +
a convex quadrilateral with at least one pair of parallel sides is referred to as a trapezoid in American and Canadian English but as a trapezium in English +
Common in OSPAR Regions II, III, IV +
Free-swimming larva characterised by apicla tuft of cilia and a girdle of cilia around the midregion (see Stachowitsch, 1992, Rupert & Barnes, 1996). +
Cone with flattended top (Olenina ''et al.'', 2006) +
An organism that lives in a tube of its own construction (e.g. mucus, bound sand grains, Calcium carbonate etc). +
