engleskiThis species is a smooth-backed (lacking an interdorsal ridge) shark, with a low first dorsal fin originating over or behind the pectoral fin free rear tip. Adults' first dorsal fin anterior margin (from the origin of the fin to its apex) is as long as the distance from the apex to the free rear tip, so that apex makes an equilateral triangle with its origin and free rear tip; height of the first dorsal fin is about 8-9% of the total length. The second dorsal fin originates over the midpoint of the anal fin base. The caudal fin measures about one fourth of the total length. A series of conspicuous pores (hyomandibular pores) are located behind the eye. The upper teeth have long triangular cusps that become increasingly oblique towards the corners of the mouth, these have a weak notch or lack a notch on their medial edges, and a strong notch on the outer edges. Edges of the first four teeth have coarse serrations from the bases up to the notch and finer serrations from the notch to the tip and these coarse serrations disappear by the fifth or sixth tooth. Subsequent teeth have inner edges with uniform fine serrations from base to tip. The five or six outermost upper teeth have strongly oblique cusps with nearly straight inner margins and a strong notch on the outer margin while the lower teeth are erect and have cusps with a few coarse serrations at their bases and finer serrations towards the tips. Teeth number U:14-1-14; L:13-13. Dermal denticles are characteristic with a central strong ridge terminating in a long point, and two shorter ridges on wing-like sides; dorsal surface of the denticles has a coarse microsculpture. Body color gray above and dirty white below, unmarked fins (Ref. 86285).

hrvatskiOva vrsta je je glatka-podlogom (nedostaje interdorsal grebena) morski pas, s niskim prva leđna peraja podrijetlom preko ili iza prsne peraje slobodan stražnji savjet. Odraslih prvi leđna peraja prednji rub (od ishodišta Peraja za svoj vrhunac) je sve dok udaljenost od vrška do free stražnji savjet, tako da vrhunac čini jednakostranični trokut porijekla i slobodan stražnji savjet; Visina prva leđna peraja je oko 8-9% ukupne duljine. Druga leđna peraja potječe preko središnje baze analne peraje. Repne peraje mjere oko četvrtine ukupne duljine. Niz primjetan pore (hyomandibular pore) nalaze se iza oka. Gornji zubi su dugo trokutasti cusps koji postaju sve više koso prema uglovima usta, to su slabi bod ili zarezati na rubovima medijalni i jaka zarezati na vanjske rubove. Rubovi prva četiri zuba su grubo oštrici od baze do zarez i finije oštrici od zarez na rtu i ove grube oštrici nestati po peti ili šesti zub. Naknadne zubi imaju unutarnji rubovi sa odori dobro oštrici od baze do vrha. Pet ili šest najudaljenije gornji zubi imaju snažno kosi cusps gotovo ravno unutarnje margine i jaka zarezati na vanjske margine dok donji zubi su uspravno i cusps s nekoliko grubo oštrici u svoju bazu i finije oštrici prema savjete. Zubi broj U:14-1-14; L:13-13. Kožni denticles su karakteristične Srednja jaka greben završava dugo točku, i dva kraća grebena na krila strane; dorzalnoj površini u denticles je grubo microsculpture. Tijelo boja siva gore i prljavo bijelo ispod, neoznačeni peraje (Ref. 86285).
