Broadnose sevengill shark
Platneus-sewekiefhaai
Squalus eepedianus Peron, 1807: 337 (Tasmania) . Heptranehias peetorosus: Smith, SFSA No. 3*. Heptranehias eepedianus: Smith, SFSA No.
2*. Notorynehus eepedianus: Bass et aI., 1975: 14* .
Snout length less than distance between lower ends of first gill slits;
orbit length 1.6-3.0 in least depth of caudal peduncle. Six rows of large
teeth on each side of lower jaw. Precaudal vertebrae 71.
Body pale grey dorsally, white below; dorsal surface of
body and fins speckled with black spots. Ovoviviparous.
Mature at about 2 m; attains 3 m. Commonly enters shallow
water and often caught by anglers from shore. All oceans
(except North Atlantic and Mediterranean Sea); apparently an anti-tropical species, the report of its presence in
Indian waters is dubious. Our records range from Algoa
Bay to Namibia.
