Known in Australia as Grey Nurse Sharks, these fierce-looking , if they are usually harmless to humans, predators are #1 in this list of wild baby predators with very good reason.

Female Sand Tiger Sharks have two wombs, and each of them produces many eggs. The eggs hatch while still inside the womb..

The Sand Tiger embryos soon develop sharp teeth and start killing and eating their brothers and sisters and any unfertilized eggs in the womb, until there is only one embryo left alive in each womb.

As a result, the mother only gives birth to two pups , the last survivor of each womb, and since they fed abundantly in the womb, they are already quite big when they are born, around one meter long!

The Sand Tiger shark is therefore the only fratricide in this list that starts killing their siblings before being born; at the moment of its birth, it is already an experienced killer.

This brutal survival strategy is known as intrauterine cannibalism, and was discovered in 1948 when a scientist, who was probing the womb of a Sand Tiger Shark, was bitten in one hand by one of the embryos!

Although intrauterine cannibalism has been reported in other species of sharks, including the Great White Shark and even the Basking Shark , a placid, harmless plankton-eater as an adult..

Great White Shark and the Basking Shark feed only on unfertilized eggs while in the womb. The Sand Tiger Shark is the only shark known to cannibalize other embryos in the womb.
