Results for “lateral line scale”

This species is considered endangered across its native range, but has recently begun to appear in the hobby a little more often as a result of commercial farming. It's still by no means common though. Superficially it looks very similar to the much commoner Northern purple spotted gudgeon (Mogurnda mogurnda), but can be distinguished by the presence of only 30-36 scales along its lateral line, (as opposed to 37-48 in M. mogurnda), and a higher degree of red spotting in the second dorsal fi...

N. selangoricus is most similar to N. spiniferus since it possesses acuminate scales above and below the lateral line on the caudal peduncle, a feature not shared with any other congener. It can however be distinguished by the following characters: presence of 8-12 very regular dark bars on flanks (vs. 10-13 irregularly-shaped bars in N. spiniferus), 3-5 times...

This species occasionally appears in the ornamental trade, usually as 'striped hill trout' or 'banded hill trout'. It can be distinguished from congeners by the following combination of characters: lateral line complete with 40-42 scales; barbels absent; 10-13 anal-fin rays; body with 9-11 dark blue vertical bars; last dorsal-fin ray extending to caudal-fin base.

It can be distinguished from other members of the genus by the following characters: lateral line absent or perforating only 2-5 scales; pharyngeal teeth hooked; body size small, not exceeding 30 mm SL; body depth less than 25 % SL; colour pattern comprising a dark bluish lateral stripe extending from the eye to the caudal peduncle, typically, but not always, forming 2-5 circular spots along its length.

P. chola was retained in Puntius sensu stricto, of which members are defined by the following combination of characters: adult size usually less than 120 mm SL; maxillary barbels absent or present; rostral barbels absent; 3-4 unbranched and 8 branched dorsal-fin rays; 3 unbranched and 5 branched anal-fin rays; last unbranched dorsal-fin ray weak or strong and unserrated; lateral line complete with 22-28 pored body scales...

This species is sometimes referred to as 'Hora danio' or Salween danio'. It is distinguished from similar-looking species by a combination of characters as follows: lateral line complete or incomplete with 22-33 pored scales; absence of infraorbital process; 7 branched dorsal-fin rays; usually 10 or 11 branched anal-fin rays; barbels absent or rudimentary; flank markings comprising a series of narrow vertical bars on the anterior portion of each flank, fol...

The five species which currently comprise Luciosoma can be distinguished by elements of colour pattern. Popta described the colour pattern of L. pellegrinii as follows: body colour olive dorsally, with dark-edged scales, yellow ventrally; a lateral series of dark spots on the flank forming a midlateral band which extends onto the opercle but not the head; 4-8 blackish-brown, distinctly-separate spots on the lateral line; fins yellow; dorsal and anal fins with a blackish-brown band; anterior half of some pectoral-fin rays blackish-brown...

Boulengerella differs from Ctenolucia, the only other genus currently contained in the family Ctenolucidae, by a series of derived features including possession of 87-124 (vs. 45-50) lateral line scales, presence of a strongly (vs. weakly) developed fleshy appendage at the tip of the snout and absence (vs. presence) of fleshy flaps on the lower jaw. Within the order Characiformes the family Ctenoluciidae is also distinguished by a set o...
