Like other members of its family, the copper shark is viviparous, in which the yolk sac of the developing embryo, once depleted, is converted into a placental connection through which the mother delivers nourishment.
The hardnose shark is viviparous; like in other requiem sharks, once the embryos exhaust their yolk supply, the empty yolk sac develops into a placental connection through which the mother provides nutrition.
Like all hammerhead sharks, the smalleye hammerhead is viviparous: when the developing embryos exhaust their supply of yolk, the depleted yolk sac develops into a placental connection through which the mother delivers nourishment.

Like other requiem sharks, the Australian blacktip shark is viviparous: once the embryos exhaust their yolk supply, the depleted yolk sac develops into a placental connection through which the mother provides sustenance.
Like other hammerheads, the smooth hammerhead is viviparous: once the young exhaust their supply of yolk, the empty yolk sac is converted into a placental connection through which the mother delivers nourishment.
