WATCH: Protecting tiger sharks in the Bahamas


On this episode of TechKnow, contributor Phil Torres joins a team of scientists and conservationists at The University of Miami in the Bahamas. The team spends a week tagging and tracking around 20 tiger sharks to learn more about their habitat and mating cycles. 

Tiger sharks are apex predators whose survival has a profound impact on other species in the sea. The warm waters where they track these sharks appear to be a good habitat for females to spend their 10- to 15-month gestational period. Using veterinary ultrasounds, they can determine—in real time—whether a shark is pregnant and, if so, how far along.
