Etymology: Scyliorhinus: skylion, Greek for dogfish or small shark; rhinus, from rhine (Gr.), rasp, alluding to a shark’s jagged, rasp-like skin. (See ETYFish); duhamelii: In honor of Henri-Louis Duhamel du Monceau (1700-1782), French physician, naval engineer and botanist, who first noted the differences between this species and S. canicula in 1777. (See ETYFish).

كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
This species is distinguished from all its congeners by the following characters: (1) color pattern composed of scattered dark spots of varied sizes that also form aggregations (vs. no dark spots in S. capensis, S. comoroensis, S. hesperius, S. meadi, S. torazame, S. torrei; reticulated pattern in S. retifer; predominant dark spots greater than spiracles in S. cervigoni, S. garmani, S. haeckelii, S. stellaris; spots with well-defined borders and not forming aggregations in S. boa, S. cabofriensis, S. canicula, S. ugoi); (2) shallow nasoral grooves, the posterior nasal flaps laterally situated (vs. no grooves and posterior flaps on the posterior border of excurrent apertures in other species, except S. canicula); (3) distance between nasal flaps 3.5-5 times smaller than width of the anterior nasal flap (vs. 6-7.5 times smaller in S. canicula; two times in all other species); (4) lower labial furrow 1.7-2.4 times smaller than mouth width (vs. more than 3 times in other species, except S. canicula) (Ref. 120402).
Occurs along the continental shelves, a benthic dweller (Ref. 120402).
