Comprimento de primeira maturação / Tamanho / Peso / Idade

Maturity: Lm 165.0, range 150 - 180 cm
Max length : 270 cm TL macho/indeterminado; (Ref. 9909)

Biologia     Glossário (p.ex. 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, mainly on prawns and crabs (Ref. 9909, Ref. 114953). Ovoviviparous (Ref. 50449). Maturity size at 150-180 cm TL; born at 38-40 cm TL (Ref. 114953). 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).

Ciclo de vida ou comportamento de acasalamento Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas

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).
