Short Description
A large thresher with relatively small eyes, curved, narrow-tipped pectoral fins, a narrow-tipped caudal fin, and a conspicuous white patch over the pectoral fin bases [536]. Second dorsal origin well behind the rear tip of the pelvic fin (Ref. 559). Upper lobe of caudal fin very long and strap-like, about as long as or longer than length of rest of shark; lower lobe short but well developed [20050]. Brown, grey, blue-grey, or blackish on back and underside of snout, lighter on sides and abruptly white below; a white area extends from the abdomen over the pectoral-fin bases; pectoral-, pelvic-, and dorsal fins blackish, white dots sometimes present on pectoral-, pelvic-, and caudal- fin tips [20050]. Diet: US. Pacific Coast (data base: 165 stomachs examined, 107 contained food representing a total of 20 taxa): northern anchovy (Engraulis mordax) was the most important in the diet (GI1 = 48.2), followed by Pacific hake (Merluccius productus; GI1 = 31.2), Pacific mackerel (Scomber japonicus; GI1 = 24.8), and Pacific sardine (Savdinops sagax; GI1 = 9.2). Of the invertebrates, squid (Teuthoidea, including Loligo opalescenr; GI1 = 6.3), and pelagic red crab (Pleuroncodes planipes; GI1 = 6.6), were also important. [13743]; US. Pacific Coast (difference bettween an cool-water oceanographic regime, July 1999 through May 2000 and an warm-water/transitional period, August 1998 through January 1999): Of the samples examined from the cool-water period, only 8 prey taxa were found, revealing a narrower trophic spectrum than found during the previous warmwater/ transitional period, when 20 prey taxa were identified. As in the warm-water/transitional period, northern anchovy (Engraulis mordax) was the most important overall prey, even more dominant than in the previous period. Additionally, market squid (Loligo opalescens) was second in importance and dramatically more prevalent in the cool-water period than in the warm-water/transitional period. Other important diet items in the cool-water period, in descending order of importance, were “unidentified teleosts”; Pacific sardine (Sardinops sagax); Pacific hake (Merluccius productus); and Pacific or chub mackerel (Scomber japonicus): these were also among the top six items in the previous warm-water/transitional period. [16893];

Cosmopolitan in temperate and tropical seas [1388]. Western Atlantic: Newfoundland, Canada to Cuba, Gulf of Mexico, Venezuela, Brazil to Argentina. Eastern Atlantic: Norway and British Isles to the Mediterranean, Morocco, Ghana and Côte d"quot;Ivoire; also Cape Province, South Africa. Indo-Pacific: scattered localities from the Gulf of Aden and East Africa to the Hawaiian, Society and Fanning islands. Eastern Pacific: Canada to Chile. Population considered reduced (R) in the US Atlantic waters; lower risk/conservation dependent (LR/CD) in US Pacific waters; data deficient (DD) in the rest of Atlantic and rest of Pacific [20064]. Highly migratory species, Annex I of the 1982 Convention on the Law of the Sea [20076]. Source:
