The UK reporting:
Twitter user @stuart appears to have started the shark discussion by tweeting a screenshot from the Ocearch shark tracker and saying: “sharks are amassing on the east coast.”
They added: “I occasionally log in to check that the nearest Great White is at least 2000 miles away.”
The Twitter user was then shocked to be notified of around 100 sharks very close to the East Coast.
One person replied: “Is this normal? Or could this be a sign of a natural disaster? Or am I overthinking this?”
