Biology     Glossary (e.g. epibenthic)

Found over sandy and muddy bottoms. Feeds on bottom-living invertebrates and fishes. Ovoviviparous, gestation about 4 months and about 6 to 9 young are produced.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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). Distinct pairing with embrace (Ref. 205).
