Famed great white shark Lydia strolls into Canadian waters

Saturday, November 5, 2016, 7:33 PM - No one likes to be snuck up on by a great white shark, but here's one that has the courtesy to let you know it's in the neighbourhood.

Known as Lydia, this beastie is 4.4 metres long, and weighs about 2,000 pounds (900 kg), according to OCEARCH, a scientific initiative that captures and tags sharks to track their movements. 

Lydia was first tagged in 2013 near Jacksonville, Florida, according to OCEARCH. Every now and then, the tracker will "ping" her location, letting researchers trace her movements, and on Friday the shark was coming quite close to Nova Scotia, according to its slightly snarky Twitter feed:

The shark has more than 28,000 followers on Twitter, and her profile includes an offhand "Oh, Canada eh." She announced her approach to Canadian waters on Friday night.

Lydia claims on her profile to be the first great white shark to ever cross the ocean, which might be a slight stretch: OCEARCH's tracking suggests Lydia has a wide range, up and down the coast of North America, and as far out as the mid-Atlantic ridge, though that's as far as the tracker goes. Still, she has travelled more than 57,000 km since being tracked, which is still quite the odyssey.

Though many people are frightened by sharks, most have no interest in humans, and will rarely attack unprovoked. In many cases, the attacking shark may have mistaken the human for prey.

The Florida Museum of Natural History, which runs an International Shark Attack File, counted 98 unprovoked attacks on humans in 2015, worldwide. Of those, only six were fatal.
