Life Cycle
provided by Fishbase
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). Off southern China, the gestation period is about one year and parturition takes place in June or July.
Trophic Strategy

Caught throughout the year in coastal waters of southern China. Feeds on small benthic animals.

Biology

Dwells near shore in sandy mud bottoms (Ref. 11230). Caught throughout the year in coastal waters of southern China. Feeds on small benthic animals. Ovoviviparous (Ref. 50449). Males mature at 38-40 cm TL, females at 39-44 cm TL; born at ca. 16 cm TL. Produces litters of 2-9 pups (Ref. 114953). Used as `kamaboko' material (Ref. 637).
