The main part of the body is covered with cycloid scales, but unlike females, males have also ctenoid scales on the head on the eye-side and on the trunk behind the head and close to dorsal and anal fins.
Scales on body progressively larger posteriorly, scale rows irregular, especially anteriorly; cheek fully covered with small scales; opercle naked except three scales at upper anterior corner; scales cycloid on head and anterodorsally on body, ctenoid posteriorly; scales ventrally on abdomen and chest cycloid; cycloid scales on pectoral-fin base; no scales on fins except for about three rows at base of caudal fin, smaller than last row on caudal peduncle.
Then ridged scales, the functional-morphologically analogous forms of ctenoid scales, appeared on the posterior trunk, and eventually the smooth scales were replaced by ridged, species-specific scales, except on the head and leading edges of fins, where smooth scales persist; the posterior part of the head carried scales of transitional type.
96) ctenoid, with 4-8 primary radii in anterior field only; radii deeply cleft at scale margin; focus located on posterior third of scale (Daniels 1996).
Bryaninops earlei differs from all congeners in having large ctenoid scales (22-25 in longitudinal series); it is similar to B.
They found that, despite superficial similarities, the ctenial spines on the ctenoid scales of the cichlid Cichlasoma have a laminated construction and develop from the external layer of the elasmoid scale, whereas the dermal denticles on the head of the clupeomorph Denticeps have pulp cavities and develop like oral teeth.
Most of the body of the juvenile has very small ctenoid scales; each scale has a single denticle; the swim bladder, pectoral fins, and the conical appendix are no longer visible; and head length is 25% of the BL.
Scales of body more or less arranged in regular transverse rows and coarsely ctenoid (up to 25 ctenii on exposed posterior margins); auxiliary scales mainly confined to lateral line and anteriormost portion of body; head fully scaled except anterior edges of lips; dorsal and anal fins scaled nearly to margins except anteriorly in spinous portion where fin membranes are deeply incised; caudal fin scaled nearly to posterior margin; pectoral and pelvic fins densely scaled at base, with tiny scales extending on surface of rays (but not on membranes) nearly to posterior margin.
Larvae of northern sculpin have 35-36 myomeres, pelvic fins with one spine and two rays, a bony preopercular shelf, four preopercular spines, 3-14 irregular postanal ventral melanophores, few, if any, melanophores ventrally on the gut, and in larger specimens, two rows of ctenoid scales directly beneath the dorsal fins extending onto the caudal peduncle.
Diagnosis: Minute stout-bodied eleotrids with large ctenoid scales confined to posterior three-quarters of body (commencing after end of first dorsal fin but before origin of second dorsal fin), and no cycloid scales; head and body anterior to origin of second dorsal fin scaleless.
The name Lepidopsetta is derived from the Greek lepido meaning "scaled," a probable reference to the strongly ctenoid scales found on the ocular side of most individuals, and psetta, meaning "flatfish".
In tetras, important characters such as ctenoid scales, incomplete lateral line, naked predorsal line etc.
Antilligobius is most similar morphologically to Bollmannia and Parrella, sharing with those genera the presence of scales on the breast, belly, pectoral fin base and predominately ctenoid scales on the trunk.
Diagnosis: Trimma cheni has 8-9 scales in the predorsal midline, a row of 2-3 usually ctenoid scales along the upper border of the opercle, no cheek scales, a dark basal stripe in the dorsal fins, an elongate second dorsal spine reaching posteriorly to the bases of rays 1-4 of the second dorsal fin, the middle rays of the pectoral fin branched, a fifth pelvic fin ray which branches once dichotomously, the basal membrane connecting the inner margins of the fifth pelvic fins rays is less than 15% the length of the fifth ray, the scale pockets are not distinctly outlined with darker pigment, and, in life, there are two red to orange bars across the cheek and three diffuse yellow stripes on the body (most obvious along the caudal peduncle).
