生物学     用語集 (例 epibenthic)

Found in bays, estuaries, and near coral reefs (Ref. 12951), over sand and mud bottoms (Ref. 9710). Usually solitary or in small aggregations (Ref. 114953). However, large schools with up to 500 individuals have been reported (Ref. 12951). Feeds on clams, oysters and crustaceans (Ref. 12951). Lives to over 2 years in captivity (Ref. 12951). Ovoviviparous (Ref. 50449). Edible (Ref. 30573). Caught mainly by gill net fisheries (Ref. 114953), occasionally by bottom trawl, demersal inshore gillnet and tangle net fisheries. Utilized for its meat (Ref. 58048).

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

Males court by nipping the female's dorsum. Mating pair orient in a venter to venter position, and the male inserts one or both claspers. The pair usually rests on the substrate, with the female on top of the male. Mating lasts about 30 seconds (Ref. 12951) to 1 minute (Ref. 49562). Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). Size at birth ~60 cm WD. One large pregnant female (~130 cm WD) contained a single late-term embryo 61 cm WD (Ref.58048).
