Etymology: Notorynchus: Etymology not explained, presumably noto(s) (Gr.), back, possibly referring to posterior placement of single dorsal fin; rhynchus (L.), snout, possibly referring to broad, depressed snout (See ETYFish); cepedianus: -anus, Latin adjectival suffix that means, when attached to a name, “belonging to”: Bernard Germain Étienne de La Ville-sur-Illon, comte de [count of] La Cepède (also spelled as La Cépède, Lacépède and Lacepède, 1756-1825), author of Histoire Naturelle des Poissons (1798-1803) and Péron’s “illustrious master” (translation) in ichthyology (See ETYFish).
Eponymy: Bernard Germaine Etienne de la Ville, Comte de Lacépède (also spelled La Cepède) (1756– 1825), was a French naturalist and politician. [...] (Ref. 128868), visit book page.

Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 0; Afterflossenstacheln: 0; Wirbelzahl: 123 - 157. A large seven-gilled cowshark (Ref. 5578) with a wide head, short and blunt snout, and fusiform body. Dorsal fin small, origin may vary from over insertion of pelvic fins to over free rear tips of pelvic fins. Anal fin smaller than dorsal fin. Tooth count 15-16/13. Reddish-brown to silvery-grey or olive-brown with numerous small black spots on body and fins; cream below (Ref. 5578).
Body shape (shape guide): elongated.
Body shape (shape guide): elongated.
Found on the continental shelf, often in shallow water (Ref. 247). Occurs close inshore, in bays and estuaries (Ref. 6871), with larger individuals ranging into deeper waters offshore and deep channels in bays (Ref. 247). Usually cruising steadily and slowly near the bottom (sometimes in water as shallow as a meter), but sometimes at the surface (Ref. 247). Can dash at speed when attacking prey (Ref. 247). Feeds on anything, including other sharks, rays, chimaeras, bony fish, hagfish, dolphin and porpoise meat, seals, shark egg cases, sea snails and mammalian carrion, including rats and humans (Ref. 5578). Ovoviviparous (Ref. 50449), with 82 to 95 young in a litter (Ref. 31395). Aggressive when provoked, and regarded as potentially dangerous to people in open waters (Ref. 247). It has attacked divers in captivity and may be involved in a few shark attacks off California and South Africa (Ref. 247). Often caught by anglers from the shore (Ref. 6574). Utilized for human consumption, its skin for leather, and its liver as a source of oil (Ref. 247).
Lebenszyklus und Paarungsverhalten Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fruchtbarkeit | Larven
Ovoviviparous, embryos feeding solely on yolk (Ref. 50449), with number of young reaching 82 in a litter. Gravid females apparently drop their young in shallow bays. Size at birth between 40 (Ref. 26346) and 53 (Ref. 247) cm. Distinct pairing with embrace (Ref. 205). Gestation period 12 months. The reproductive cycle appears to be biennial (Ref. 45445).
