How do you measure free-roaming sharks without being bitten?

measure a shark out of piss can be a risky , time - consuming effort , so shark researchers from Australian universities have come up with a novel approach to safely appraise these fish underwater .

TheSave Our Seasfoundation is funding a projection to value the emergence of shark in Palau — the researchers use cameras , a good length , and the power of ratios to mold the lengths of these oceanic carnivore :

geminate television camera in housings take the sharks and a diode ( light source ) in the front of the cameras allows the researchers to synchronize frames of the video . Using head teacher originally develop for aerial photography , these researchers are then able to reckon the length of any body part and full sizing of the animal with a preciseness of a few millimeters . The technique is so accurate that the researchers can recognize private animate being by their body proportions . By repeatedly filming the same animals over a turn of year , they will be able to measure out ontogenesis pace of these sharks .
