Scientists Capture Ultrasound of Tiger Sharks in the Womb

Michele Debczak

This year’s Shark Week is one for the history books. Earlier in the week we reported the first-ever footage of a napping great white captured for the Discovery Channel special Jaws of the Deep. Now the television event has brought us what’s reportedly the first-ever sonogram of live tiger sharks in the womb.

In the above clip, spotted by The Verge, you can watch as a litter of toothy tiger sharks wriggle around inside their very pregnant mama. James Sulikowski, a professor of marine science at the University of New England, counted at least 20 babies being carried by the 12.5-foot shark.

Even though sharks are a type of fish, many species give birth to live young instead of laying eggs. Tiger sharks fall under this category, and a mother can birth up to 80 live sharks at once. Fortunately for these pups, tiger sharks aren’t known to devour each other in utero like their sand tiger shark cousins.
