Great white sharks might receive all of Hollywood's attention, but their smaller cousins, tiger sharks, are the true stuff of nightmares. Tiger sharks or Galeocerdo cuvier are the second most likely species to attack humans, and together with great whites and bull sharks form the infamous "Big Three" in the shark attack world. According to the International Shark Attack File, tiger sharks "should be treated with extreme caution and a great deal of respect".
It comes as no surprise then that even tiger shark pups are formidable beasts from the deep.
Marine biologists have recently taken a peek inside the womb a pregnant tiger shark.
The scan revealed a well-developed shark pup with jaws lined with blade-like teeth.
And yet, according to the Sulikowski Shark and Fish Conservation Lab, the 12ft-long shark was only halfway through its pregnancy at the time of the ultrasound.

The Sulikowski lab operates at Arizona State University under Dr James Sulikowski, a professor of Marine Sciences at the University of New England.
Dr Sulikowski and his team of students explore ways in which scientists can more effectively manage and conserve shark populations.
And in the process, they uncover terrifying insights into the life of these marine predators.
Sharing the shark ultrasound to Instagram, the group posted: "Baby tiger shark - check out those teeth!
