 This species of shark is an ovoviviparous species, meaning the embryos develop inside eggs, which are retained inside the mother's body until the eggs are ready to hatch.The sizes of these shark pups are thought to be 20 to 21 cm long, for both male and females examined.This species of shark lives in depths where deepwater fisheries operate, which can have a negative impact on a population of shark that is already uncommon and virtually unknown.
