A device used by researchers with Fisheries and Oceans Canada appears to have been the victim of an attack by a great white shark 300 metres under water off the coast of Nova Scotia.
Clark Richards, a research scientist with the federal department, said in an interview his colleagues are confident the bite marks on one of their ocean gliders are from the infamous predator. The serrated edges of the marks, and the pattern of the attack give away the culprit, Richards said Tuesday.
The glider’s movements, which were tracked by researchers, and damage to the device would indicate the shark attacked the bright yellow, two-metre-long device twice before the glider resurfaced.
“The shark probably hit it down deep, thought it injured it, waited for it to drift up, and then probably took another crack at it,” Richards said.
