IngliżThis 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).

MaltiDin l-ispeċi hija a ibbekjati lixxi (nieqsa xi ridge interdorsal) klieb il-baħar, bil-ġwienaħ ewwel baxx gangliji li joriġinaw matul jew wara l-ponta fuq wara bla ġwienaħ mhux. Adulti ewwel gangliji ġwienaħ anterjuri marġini (mill-oriġini tal-ġwienaħ biex l-quċċata) hija kif twil bħala d-distanza mill-quċċata sal-ponta fuq wara ħielsa, sabiex dak l-apiċi jagħmel triangolu ekwilaterali l-oriġini u l-ponta fuq wara ħielsa; l-għoli tal-ġwienaħ gangliji ewwel hija madwar 8-9% tat-tul totali. Il-ġwienaħ gangliji tieni joriġina fuq il-punt tan-nofs tal-bażi tad-denb anal. Denb il-miżuri ta ' madwar kwart tat-tul totali. Serje ta ' pori konspikwi (hyomandibular pori) jinsabu lura l-għajnejn. L-upper snien kienu cusps twil triangolari li jsir dejjem aktar oblikwu lejn il-kantunieri tal-ħalq, dawn ikollhom a b'darsa dgħajfa jew ma jkollhomx a b'darsa fuq it-truf medika tagħhom, u a b'darsa qawwija fuq it-truf fuq barra. It-trufijiet ta ' l-ewwel erba snien kienu serrations oħxon mill-bażijiet sal-b'darsa u serrations iktar preċiż mill-b'darsa sal-ponta u dawn serrations oħxon jisparixxu mill-ħames jew sitt dfir. Snien sussegwenti jkollhom it-trufijiet ta ' ġewwa ma serrations multa uniformi mill-qiegħ biex taqleb. Il-ħames jew sitt aktar imbiegħda upper snien kienu cusps oblikwu bil-qawwi mal-marġini ġewwa kważi dritti u a b'darsa qawwija fuq il-marġini ta ' fuq barra waqt li l-snien aktar baxxi huma erect u kienu cusps bi ftit serrations oħxon fuq bażijiet tagħhom u serrations iktar preċiż lejn it-truf. Snien numru U:14-1-14; L:13-13. Denticles tal-ġilda huma karatteristika mal-ridge qawwija ċentrali li jispiċċaw fil-punt twil, u żewġ ħniek iqsar fuq naħat ġewnaħ simili; il-wiċċ tad-dahar ta ' l-denticles ikun a microsculpture oħxon. Korp tal-kulur griż hawn fuq u abjad maħmuġ hawn taħt, xewk wieħed (Ref. 86285).
