Lamiopsis tephrodes differ from the wide-shouldered sharks in the following parameters: elongated snout; dorsal fins of equal height; when the mouth is closed, the lips almost completely cover the teeth, with the exception of those located on the symphysis ; front lower teeth narrow and protruding. In the mouth there are 33-40 upper and 34-40 lower dentitions. The distance between the dorsal fins is 16.2-20.4% of the total length. The front edges of the pectoral fins are slightly curved. Their length is 12.4-14.4 total length. The length of the anterior margin of the ventral fins is 7.4–9.3% of the total length and 48–53% of the length of the anterior margin of the pectoral fins. The first dorsal fin is rather small, set obliquely, the posterior border is straight or slightly concave. The free posterior tip is located in front of the base of the ventral fins. The base length is 14.9-17.1%, and the fin height is 5.6-8.1% of the total length. The second dorsal fin is large, approximately the same height as the first dorsal fin, the base length is 11.8-14.3%, and the height is 4.8-7.3% of the total length and 83-93% of the height of the first dorsal fin. The height of the anal fin is 3.8–5.6% of the total length and 70–85% of the height of the second dorsal fin, the base length is 78–98% of the length of the base of the second dorsal fin. The total number of vertebrae is 174-181, the number of vertebrae of the precaudal division is 98-100. The border between the dark (dorsal) and light (ventral) coloration of the head is clear. Dark color is not visible from below, there is no dark or light edging of the fins [1] .
