Etymology: Heptranchias: hept[a] (Gr.), seven; ranchias, etymology unclear, possibly a variant spelling of anchos (Gr.), gill, possibly with the addition of -ias, borrowed from karkharías, ancient Greek for shark (cf. Carcharias Rafinesque 1810), referring to how the seven gill openings extend down onto the throat. (See ETYFish);  perlo: From the French vernacular “Le Perlon,” pearl, probably referring to its smooth and grayish (“lisse & grisâtre”) skin. (See ETYFish).

колючие лучи спинного плавника (общее число): 0; членистые (мягкие) лучи спинного плавника (общее число): 0; колючие лучи анального плавника 0; членистые (мягкие) лучи анального плавника: 0; позвонки: 125 - 161. A narrow-headed, big-eyed small seven-gilled shark (Ref. 247). Body fusiform and slender; dorsal fin small, originating over inner margins of pelvic fins; anal fin small (Ref. 6871). Teeth wide, low and comb-shaped (Ref. 6871). Brownish grey above, paler below, sometimes with indistinct dark blotches on body; juveniles with dark-tipped dorsal and caudal fins, adults with light fin margins (Ref. 5578, 6574, 6871).

биология     глоссарий (например epibenthic)

Found on the outer continental and insular shelves and upper slopes in depths of 100 to 400 (Ref. 13573, 11230), also inshore and down to 1,000 m (Ref. 6871, 11230). Feeds on small sharks and rays, small bony fish, shrimps, crabs, lobsters, squid, and cuttlefish (Ref. 5578). Ovoviviparous (Ref. 205), with 9-12 young born per litter (Ref. 247). Very active and aggressive when captured and quick to bite but too small to be very dangerous to people (Ref. 247). Liver utilized as a source of oil. Maximum length may reach 214 cm, but this is uncertain.
