Ever wonder what it's like to be a shark? Do they swim with other shark types, and what about chasing the ladies? We now know they do a fair bit of both - thanks to a team of clever biologists who decided to strap a small camera atop a shark's fin.
"This is our first ever shark's-eye view," says ecologist Carl Meyer.
A team of biologists from the Hawaii Institute of Marine Biology and the University of Tokyo's Atmosphere and Ocean Research Institute built a device to capture video and movement information (similar to a flight-data recorder) with help from a Japanese company called Little Leonardo. The device has a triaxial accelerometer-magnetometer but is small enough that it doesn't interfere with a shark's daily life.
Secured atop the shark's fin, the camera rode for two weeks, capturing "astounding" footage, according to ecologist Carl Meyer. "Until we deployed the cameras, we had no idea that these mixed-species shark aggregations were occurring only a few miles from our research institute."
The camera recorded Hawaiian sandbar sharks swimming closely with hammerheads and blacktip reef sharks, and chasing members of the opposite sex.
