Silvertip shark
The silvertip shark is viviparous, meaning that they give live birth. Courtship is a little different in these sharks and they are known to hold each other. Bites are normal, so much so that a female Silvertip shark has been found without a part of the dorsal fin after mating. Mating occurs in the summer. During the gestation period that could extend to a year, the embryos feed from the yolk and once the yolk is exhausted, the yolk-sac modifies itself into a placental connection through which the newborns feed from the mother.
