Yep, those small dark specks you can see in the water are actually 2-meter-long (6.2-foot) sharks.
Aerial photos and video footage captured the epic scene of an estimated 10,000 blacktip sharks (Carcharhinus limbatus) migrating along the shores of Palm Beach to Jupiter, Florida on the morning of February 12.
While huge congregations of these sharks are not out of the ordinary, they’re usually found much further south in Miami-Dade and the Ft. Lauderdale area. Biologist Dr. Stephen Kajiura, from Florida Atlantic University, helped document the en masse migration and is working on a tracking project to uncover the source of this behaviour change.
Speaking to CBS12 local news, he added, "There are literally tens of thousands of sharks a stone's throw away from our shoreline.

"You could throw a pebble and literally strike a shark. They are that close."
Dr. Kajiura believes that rising ocean temperatures could have meant the sharks no longer have to travel as far south towards the equator. Speaking to ABC, he said, “One of the ideas may be that as they are getting south, if they are in a suitable habitat, then why not stay.”
Fear not if you’re a Floridian with a phobia of sharks. He added that blacktip sharks have a particularly “skittish” attitude towards humans and are much more likely to swim away than confront you. As such, fatal attacks from blacktip sharks are unheard of, not just in Florida but worldwide. But then again, unprovoked shark attacks are rarer than you’d think anyway.
