    Sorry this took awhile. I've got 8 absolute banger videos I'm currently working on through April 2021 but it turns out the Rona slows things down a bit. They will be worth the wait! For updates, follow me on social stuff @MarkRober.

    To be fair, that wasn't just fish blood it was blended whole fish, with that said, it's obvious that sharks will be attracted to raw smell of blended flesh... I think it would've been the same if you blend a chicken.
