Adults are found on the continental shelves from the intertidal region to at least 200 m depth. They feed on crabs, ghost shrimps, mantis shrimps, isopods, squids, polychaete worms, tunicates and small bony fishes. Viviparous (with a yolk-sac placenta), with 3 to 5 young in a litter. Size at birth between 19 and 21 cm. Readily kept in captivity. Utilized for human consumption. Marketed fresh, smoked and frozen (Ref. 9987).
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Viviparous with a yolk-sac placenta; with 3 to 5 young in a litter. Size at birth ranges from 19-21 cm (Ref. 244). Distinct pairing with embrace (Ref. 205). Polyandry is a common life history strategy among the elasmobranchs and for M. henlei, the occurrence and frequency of polyandric behavior may vary depending on location and density of breeding individuals (Ref. 95902).
