Sharks Strapped with Eye Cameras [VIDEO]
In a new study, scientists have tied cameras to ocean creatures to see how sharks live and eat.
Researchers from the Universities of Hawaii and Tokyo are tracking sharks with complex sensors and cameras, including dispensable cameras that are meant to be swallowed. There is not enough information on sharks among other marine animals because of how fearsome they can be.
"What we are doing is really trying to fill out the detail of what their role is in the ocean," stated Carl Meyer, an assistant researcher at the Hawaii Institute of Marine Biology at the University of Hawaii at Manoa, "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."
The footage shows how sharks move in repetitive loops through the sea bed, and sometimes you can catch them pursuing a female shark, or swimming in a mixed school of sharks, alongside hammerheads for example.
Contrary to popular belief that sharks glide through the water, scientists have realized from the footage that the marine beasts actually power swim to move through the water. Deep sea sharks move in slow motion compared to other sharks in the more shallow waters.
"These instrument packages are like flight data recorders for sharks," Meyer said in the release. "They allow us to quantify a variety of different things that we haven't been able to quantify before." It has really drawn back the veil on what these animals do and answered some longstanding questions."
Until now, sharks have been observed in captivity. This altered the organic information that studiers searched for. This study is important because sharks rule the food chain in the ocean. Therefore, they are important to the ecosystem, and it is ideal that they research the sharks in their own habitat.
