Sharks have provided a lot of new insight into their lives and they have done this with the use of video cameras. Sharks swimming along the seabed and in mixed groups have been captured using underwater cameras strapped to the predator’s fins per the Telegraph UK.
The filming is part of a research project to map the life of a shark, to track what they eat, and the way they move through the ocean. For the first time ever, sharks were fitted with cameras and video recorders to capture their journey underwater and record how they interact with other species.
The video footage shows how sharks move in repetitive loops across the sea bed, and even shows how they pursue the opposite sex. They are also shown swimming with different species of sharks, including hammerheads.
“What we are doing is really trying to fill out the detail of what their role is in the ocean,” said 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 video reveals sharks tend to use powered swimming to move through the water rather than gliding, which goes against what scientists have previously thought. It also provided insight on deep water sharks, proving they move in slow motion compared to those swimming in more shallow water.
Up until this point, sharks have mostly been observed in captivity and have been tracked only to where they have travelled.
What is up next? Scientists are also piloting a project to understand the eating habits of sharks by using instruments that are eaten by sharks to track their ingestion and digestion of prey.
