Pellonula vorax Günther 1868

Diagnosis: Body moderate or fairly deep, its depth 23-30% of standard length; 1 or more scutes beginning in front of base of first pectoral finray, with 11-16 pre-pelvic and 8-11 post-pelvic scutes, and a total of 20-25 scutes, first pre-pelvic scute always longer and better developed than following scutes lacking ascending arms; lower jaw slightly projecting, teeth at symphysis large in large specimens; pre-maxilla teeth well-developed, fairly straight and outward pointing, an indented toothless gap at centre of jaw; lower gillrakers 24-37, equal to or longer than corresponding gill filaments; silver stripe along flank (Ref. 188, 2244, 81269, 81631). It resembles Pellonula leonensis, which has small and inward-curving teeth and no pre-pectoral scutes (Ref. 188, 81269, 81631). The absence of large canine teeth in the upper jaw distinguishes it from Odaxothrissa (Ref. 188).Description: Body moderate or fairly deep, its depth 23-30% of standard length (Ref. 188, 2244). Head length about 30% of standard length (Ref. 2244). Lower jaw projecting, with well-developed teeth, but no enlarged canine teeth; maxillary extending to below anterior border of eye or a little beyond (Ref. 1878, 2244, 3022). A group of teeth on each side of the palatinum; generally 3 rows of teeth on the tongue; conical teeth relatively well developed on the dentary and pre-maxillary; pre-maxillary teeth are directed towards the outside of the mouth; length of supra-maxillary and width of maxillary respectively 58.6-75.8% and 16.2-22.0% of maxillary length, whose base bears up to 40 small conical teeth (Ref. 2244). First gill arch with 34-54 gill rakers, of which 24-37 on the lower limb, generally longer than the corresponding filaments on the first gill arch (Ref. 2244, 2849, 81269, 81631). Dorsal fin with 15-19 rays, the first dorsal-fin ray slightly in front or behind the insertion of the pelvic fin; anal fin with 16-21 rays; pectoral fin with 12-18 rays; pelvic fin with 8 rays; length of pectoral fin generally more than half the pectoral-pelvic fin distance; caudal fin deeply forked, with pointed lobes (Ref. 1878, 2244, 2849, 81269, 81631). Cycloid scales; 38-48 scales on longitudinal series; 13-14 scales in transverse series (Ref. 1878, 2244, 3032). First pre-pelvic scute better developed and longer than following ones lacking ascending arms and located at isthmus in front of the base of the first pectoral fin ray; 10-16 pre-pelvic scutes and 8-11 post-pelvic scutes (Ref. 188, 2244, 2849, 81269, 81631). Vertebrae 42-43; with 21-26 abdominal vertebrae, 17-23 caudal vertebrae and 10-12 predorsal bones (Ref. 2244, 41578).Colouration: Ground colour in preserved specimens variable from yellow-brown to yellow-gray; operculum, ventral region and flanks usually lighter (Ref. 2244, 2849, 81269, 81631). Silver stripe along flank (Ref. 188).

Anadromous. Fish that ascend rivers to spawn, as salmon and hilsa do. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.

Dorsal spines (total): 0; Dorsal soft rays (total): 15 - 19; Analspines: 0; Analsoft rays: 16 - 21; Vertebrae: 42 - 43

Found in rivers and streams (Ref. 188). It forms large schools in lower courses of rivers (Ref. 2244, 43836), and is very abundant in brackish water habitat (Ref. 86940).
