Instead of a bird's eye view, researchers from the Universities of Hawaii and Tokyo opted for the opposite; they went to the depths of the ocean to better understand one of the world's most feared creatures.

Sensors and video recorders were attached to the sharks' fins along with an instrument ingested to find out a little more about feeding habits.

The cameras caught footage researchers had never before seen until now.
In a press release, an assistant researcher said, "It is all about getting a much deeper understanding of sharks' ecological role in the ocean, which is important to the health of the ocean and, by extension, to our own well-being."

They also discovered that, contrary to previous beliefs, sharks use powered swimming more often than a gliding motion to get across the ocean floor. (Via University of Hawaii)
LiveScience points out this is the closest researchers have come when tracking sharks. In the past, the animals were observed in captivity, and migration habits were the focus of previous tracking efforts.
Researchers also studied other fishy predators like tuna. They say the findings could help guide future conservation efforts.
