簡単な記述 形態学 | 形態計測学

背面の脊椎 (合計): 0; 背鰭 (合計): 0; 肛門の骨 0; 臀鰭: 0. A stout shark with a moderately long, rounded snout, high, triangular, saw-edged upper teeth, and an interdorsal ridge; 1st dorsal fin very large and erect (Ref. 5578). Grey-brown or bronzy with no prominent markings, white below (Ref. 5578). Fins plain or with slightly dusky tips (Ref. 5485).

生物学     用語集 (例 epibenthic)

Found inshore and offshore, on continental and insular shelves and adjacent deep water (Ref. 244). Common at bays, river mouths and in harbors; avoids sandy beaches and the surf zone, coral reefs and rough bottom, and surface waters (Ref. 244). Coastal-pelagic, but usually bottom associated at 1-280 m (Ref. 58302). Sometimes in oceanic waters (Ref. 9997). Known to make extended seasonal migrations in some parts of its range (Ref. 6871). Feeds mainly on bony fishes, also small sharks, cephalopods, and shrimps (Ref. 5578), rays and gastropods (Ref. 5213). Youngs feed heavily on crustaceans such as blue crabd and mantis shrimp (Ref. 93252). Viviparous (Ref. 50449). Sexual dimorphism is evident in thickness of skin layer of maturing and adult females (Ref. 49562). Females live as long as 21 year; males 15 years (Ref. 27549). Populations are segregated by age. Young readily kept in aquaria (Ref. 244). Utilized for human consumption, for leather and oil (Ref. 244). Marketed fresh, smoked, dried-salted and frozen; fins are valued for soup (Ref. 9987). Used in Chinese medicine (Ref. 12166). Records to 300 cm TL uncertain (Ref. 9997). TL to 300 cm (Ref. 26938). Angling: an inshore fish and a good light-tackle fighter (Ref. 84357).

Life cycle and mating behavior 成熟 | 繁殖 | 放精 | | 生産力 | 幼生

Viviparous (Ref. 26281), placental (Ref. 50449), 1-14 pups in a litter; 56-75 cm at birth (Ref. 2334); gestation period of 12 months (Ref.58048). Distinct pairing with embrace (Ref. 205). Sexual dimorphism is evident in the thicker skin layer of maturing and adult females (Ref. 49562). This thickened skin may serve as protection from the 'bites' the female species receive from the males during precopulation and in the rugged conditions of the rock and coral environment where they live (Ref. 49562). Pups are born from Feb. to April in Northeastern Taiwan (Ref. 37027).
