Once the required head at the last emitter of the lateral line is determined, the lateral line is dimensioned through the step-by-step method, with calculation from the last emitter (Yildirim, 2010).
adanensis has II-III un-branched, 7-9 branched fin rays in dorsal fin, III un-branched, 8-11 branched fin rays in anal fin and 44-59 scales in lateral line (Fig.
Determination via the lateral line in the mottled sculpin.
Scales cycloid; head scaled except interorbital space, snout and chin; opercle covered by seven large scales; cheek with two horizontal rows of scales below eye; naked lower flange of preopercle thin, greatest width at angle about 2 in orbit diameter in holotype; base of dorsal and anal fins with single row of large elongated scales, one per membrane; last pored scale on lateral line at base of caudal fin enlarged and pointed; terminal scale on midline just posterior to last pored scale very enlarged and pointed; no scales on paired fins; pelvic fins with median ventral process of two elongate scales about three-fourths the length of pelvic spine, thin axillary scale of each pelvic fin about three-fourths the length of pelvic spine.
Humeral spot located just behind posterior margin of opercle extending from first scale of lateral line series, just above spot and posterior to thin unpigmented there is a second diffuse projection of melanophores.
This ancestor was probably a predatory marine fish with good eyesight, jaws and teeth and a lateral line system for detecting water movements, visible as a stripe along the flank of most fishes.
However, lateral line scales are easily distinguished from other scales by a pore or line on the scale and can, therefore, be identified among prey remains (Daniels, 1996; Roberts et al.
When smoked Atlantic salmon is processed, lateral line dark meat is removed before the product is packaged.
In an earlier study, Gardiner and Atema found that sharks use what Atema described as a "fantastically sensitive organ" called a lateral line, which runs the length of their bodies and picks up vibrations in the water.
