Forget a bird's-eye view — researchers from the Universities of Hawaii and Tokyo went
to the depths of the ocean to better understand one of the worlds most feared creatures.
With "shark's-eye" cameras, researchers can check out what the ocean's top predator is
up to under the deep blue. (Via YouTube / infernalzen)
Sensors and video recorders were attached to the sharks' fins along with an instrument
ingested to find out a little more about feeding habits. (Via University of Hawaii / Mark Royer)
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." (Via American Geophysical Union

Researchers tagged a tiger shark, a bluntnose sixgill shark, a Galapagos shark and sandbar
sharks. The cameras caught footage researchers had never before seen until now.
From the shark's perspectives, you can see them interacting with other fish, swimming
in mixed schools and trying to grab the attention of lady sharks. (Via American Geophysical

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.
