Biology
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 [733]. With 4 in a litter [1658]. Size at birth 45 cm [1658]. Found on sand and mud bottoms near reefs and wrecks [1658], usually in shallow water. Sometimes found in the water column [1658]. Feeds mainly on bottom crustaceans and mollusks.
