Mating by this species has never been observed, but females have been found with mating scars on their caudal fins. Therefore, it is inferred that, as is the case with most sharks, males bite females until they submit. Fertilization occurs internally. ("Greenland Shark, Elasmobranch Research, and Education Group", 2005)
Mating System: Polygynandrous (promiscuous)
Mating has never been observed in this species and little information is available concerning reproduction in Greenland sharks or related species. ("Greenland Shark, Elasmobranch Research, and Education Group", 2005; Compagno and Fowler, 2005; Compagno, 1984)
Key Reproductive Features: Iteroparous; Gonochoric/gonochoristic/dioecious (sexes separate); Sexual; Fertilization; Fertilization :: Internal; Ovoviviparous
There is no specific information on parental investment in Greenland sharks. However, most sharks are independent immediately after birth. Females provide developing embryos with rich food sources to support their development.
Parental Investment: Pre-fertilization; Pre-fertilization :: Provisioning; Pre-fertilization :: Protecting; Pre-fertilization :: Protecting :: Female; Pre-hatching/birth; Pre-hatching/birth :: Provisioning; Pre-hatching/birth :: Provisioning :: Female
