生物学特性     字汇 (例如 epibenthic)

Occurs inshore and offshore, from the intertidal to offshore continental and insular shelves (Ref. 9909). Adults are found offshore waters while young individuals are found inshore on sand flats, around atolls, and in mangrove swamps (Ref. 6871). Feeds on shellfish (Ref. 9909). Ovoviviparous (Ref. 50449). Reported to live and breed permanently in fresh water (Ref. 6871). Probably the major commercial guitarfish in the Western Central Pacific (Ref. 9909). Caught regularly by demersal tangle net fisheries operating throughout the area. Utilized for its meat, fins (both very high value), skin and cartilage (Ref.58048). Reported to attain a maximum length of 4 m (Ref. 58784).

Life cycle and mating behavior 成熟度 | 繁殖 | 产卵场 | | 孕卵数 | 仔鱼

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). Born at 38-40 cm TL (Ref.58048).
