Elasmobranchii 板鳃亚纲 (鲨鱼与 鱼) (sharks and rays) > Lamniformes (Mackerel sharks) > Lamnidae (Mackerel sharks or white shark)
Etymology: Lamna: From the Greek lamia, a large and voracious shark, originally from Lamia in Greek mythology, daughter of King Belos, who revenged the murder of her children by killing the children of others, and who behaved so cruelly that her face turned into a nightmarish mask. (See ETYFish);  ditropis: di-, from dis (L.), in two; tropis (Gr.), keel, i.e., double-keeled, referring to the rudder-like projections on either side of tail. (See ETYFish).

生物学特性     字汇 (例如 epibenthic)

A coastal-littoral and epipelagic shark that prefers boreal to cool temperate waters, from the surface to at least 152 m, and is common in continental offshore waters but range inshore to just off beaches. Occurs singly or in schools or feeding aggregations of several individuals; feeds on fishes (Ref. 247). Seasonally migratory (following food prey) and segregate by age and sex where adults move further north than young (Ref. 58085). Ovoviviparous, embryos feeding on yolk sac and other ova produced by the mother (Ref. 50449). With up to 4 young in a litter (Ref. 247). Fast swimmer (Ref. 9988). Potentially dangerous but has never or seldom been implicated in human attacks (Ref. 247). Causes considerable damage to commercial catches and gear (Ref. 6885). Utilized fresh, dried or salted, and frozen; fins, hides and livers are also used, with fins having particular value; can be broiled and baked (Ref. 9988). Reported to attain at least 27 years of age and reach maximum depth of at least 792 m (in Ref. 119696).
