Tope sharks, Galeorhinus galeus, are ovoviviparous (fertilized eggs develop in the female without a yolk-sac placenta). Litter size ranges from 6-52 pups and increases according to the size of the mother. Newborn pups measure 30-36 cm at birth. In Australia, newborns and juveniles aggregate in nurseries found in shallow waters and move into deeper coastal waters during winter after which they return to the nursing grounds.
