Not sure what to make of this but it is very quite unsettling.

unsettling, naaaa.
there are so many juvenile's swimming around California at the moment, many vids in the cyber world with proners sups and shorties all surfing with them.
Still I am glad that that's not a standard occurrence at the places that I surf at.

Yeewww!

Juvenile or not, sharks eat meat, and we're made of meat!

It's official sups have become such a plague that not even the sharks are safe

Come on guys... it looks like a Black Tip Reef Shark. Max length about 2m. They are more likely to run away than bite...

Close call........................... for the shark.
