Size / Peso / Age
Maturity: Lm ?  range ? - ? cm
Max length : 40.0 cm TL maschio/sesso non determinato; (Ref. 114953)
Found in continental shelf in shallow water to at least 15 m deep. Presumably feeds on small invertebrates and fishes (Ref. 114953). Ovoviviparous (Ref. 50449). Males mature at ca. 32 cm TL, females at ca. 35 cm TL (Ref. 114953).
Life cycle and mating behavior
Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve
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).
