IngliżDiagnosis: Pristis pectinata is easily separable from Pristis perotteti by the following characters: its first dorsal fin originates about over the origin of its pelvic fins vs. considerably in front of origin of pelvic fins in P. perotteti; its caudal fin is much shorter, but broader relative to the length of the fin, with lower lobe only faintly indicated; its rostral teeth are numerous, 23 or more on each side vs. not more than 20 in P. perotteti; its saw is relatively somewhat shorter; its second dorsal fin has the posterior margin much less deeply concave; and its pectoral fins are smaller (Ref. 6902, 81624). Pristis pectinata agrees with Pristis pristis in the shape of its caudal fin and in the position of the first dorsal fin relative to the pelvic fins, but it can be separated from P. pristis by its more numerous rostral teeth, 23 or more on each side vs. less than 20 (Ref. 6902, 81624).
Description: Long, flat, blade-like rostrum with at least 23 and up to 32 pairs of rostral spines along edges (Ref. 26938, 81624). First dorsal fin originating at same level as pelvic fin origin and base slightly longer than second dorsal fin (Ref. 81624). Caudal fin with a much larger and oblique dorsal lobe and without a clearly defined ventral lobe (Ref. 26938, 81624).
Colouration: Nearly uniform dark mouse gray to blackish brown above, paler along margins of fins; white to grayish white or pale yellow below (Ref. 6902, 81624).

MaltiDjanjosi: Pristis pectinata huwa faċilment separabbli mill- Pristis perotteti mill-karattri li ġejjin: l-ġwienaħ gangliji ewwel joriġina dwar fuq l-oriġini tal-tiegħu huwa xewk vs. konsiderevolment quddiem oriġini tax-xewk huwa fil- P. perotteti; denb tiegħu huwa ferm iqsar, imma aktar wiesgħa relattivi għall-tul tal-ġwienaħ, bl-aktar baxx tal-lobu laterali biss jidhru indikati; is-snien rostral tiegħu huma numerużi, 23 jew aktar fuq kull naħa vs. mhux aktar minn 20 fil- P. perotteti; serrieq tagħha hija relattivament ftit iqsar; tiegħu tad-denb gangliji tieni jkollha l-marġini posterjuri ferm anqas profondament konkavi; u mhux xewk tagħha huma iżgħar (Ref. 6902, 81624). Pristis pectinata taqbel mal- Pristis pristis fil-għamla tad-denb u fil-pożizzjoni ta ' l-ewwel ġwienaħ gangliji relattivi għall-xewk huwa, imma li jistgħu jiġu separati minn P. pristis mill-aktar numerużi snien rostral, 23 jew aktar fuq kull naħa vs. inqas minn 20 (Ref. 6902, 81624).
Deskrizzjoni: Twila, ċatti, bħal xafra geddum mal-pari mill-inqas 23 u sa 32 ta ' l-spines rostral tul it-truf (Ref. 26938, 81624). Ewwel gangliji tad-denb li joriġinaw fil-livell tal-istess bħala oriġini huwa ġwienaħ u bażi ftit aktar minn tieni gangliji tad-denb (Ref. 81624). Denb ma a ferm akbar u oblikwu dorsali tal-lobu laterali u mingħajr a definiti b'mod ċar bridges tal-lobu laterali (Ref. 26938, 81624).
Kolorazzjoni: Kważi uniformi griż skur tal-maws għal kannella fl-iswed hawn fuq, paler tul-marġini tax-xewk; abjad għal abjad grayish jew ċass safra hawn taħt (Ref. 6902, 81624).
