Etymology: Hexanchus: hex (Gr.), six; anchus, etymology unclear, perhaps anchos (Gr.), choke or throttle, referring to how six gill openings of H. griseus extend down onto the throat (See ETYFish); griseus: Medieval Latin for gray, reflecting the French vernacular “Le Griset,” referring to its dark-gray coloration (See ETYFish).

Snout broadly rounded, body fusiform (Ref. 6871). Anal fin smaller than dorsal fin (Ref. 6871). Brown or grey above, paler below, with a light stripe along side (Ref. 26346). Fins with white edges (Ref. 6574). Live specimens with fluorescent green eyes (Ref. 6871). Six gill slits are very long (Ref. 35388).

一隻身體很重的, 寬頭的六條鰓裂的鯊魚, 腹下的嘴具有 6 列的低﹐刀葉狀的﹐和梳狀的牙齒在兩邊.(參考文獻 247) 吻寬廣地圓的, 身體紡錘型.(參考文獻 6871) 比背鰭小的臀鰭.(參考文獻 6871) 背面褐色或灰色的﹐腹面灰白的, 沿著側邊具有一個淡色條紋.(參考文獻 26346) 鰭有白色的邊緣。 (參考文獻 6574) 活體有螢光的綠色眼。 (參考文獻 6871) 六個鰓縫非常長。 (參考文獻 35388)
Depth range reported at 0m-2500m (Ref. 125614). A deepwater species of the outer continental and insular shelves and upper slopes (Ref. 6871, 75154), islands, seamounts and mid-ocean ridges (Ref. 125614). Near bottom, occasionally pelagic, adults usually below 91 m (Ref. 58302). Juveniles may be found close inshore (Ref. 6871), while nursery areas are in very shallow waters (Ref. 125614). Found on the bottom by day, moving to the surface at night to feed, and where it may take longlines set for other species (Ref. 45445). Depth distribution related to growth and temperature, with juveniles having most shallow records and from colder, poleward regions (Ref. 58302). Generally occurs at a bottom temperature of 6 to 10°C (Ref. 125614). Feeds on a wide range of marine organisms, including other sharks, rays, chimaeras, bony fish, squids, crabs, shrimps, carrion, and even seals (Ref. 26969). Large sharks (at least 2m) take cetaceans and seals. Viviparous, very large litters of 47-108 pups (Ref. 125614). Give birth to almost 100 young (Ref. 35388). Young and adults may be segregated, with the young using inshore nursery grounds. Possibly long-lived (Ref. 125614). Is a eurytrophic predator that is capable of exploiting a wide range of prey species and habitats (Ref. 26969). A vertical migrant, it may sit on the bottom by day, and rise to the surface at night to feed (Ref. 247). It occurs alone or in groups. Adults are more sensitive to light than the juveniles and less seen in clear shallow waters, but more prevalent at night or areas with dense plankton blooms (Ref. 125614). It is locally common in bycatch and target fisheries for food, fishmeal and oil, and in sports fisheries, but vulnerable to overfishing and requires careful management (Ref. 125614). Marketed fresh, frozen, or dried salted (Ref. 247). Not known to have attacked people without provocation (Ref. 247).
