    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.

    1. You are not using actual human blood. 2. The fish 'blood' contains more than just blood, as you've added fish paste to it. The results from this test are basically invalid.

    Were the sharks attracted by the fish blood or fish meat? If you would have served the cows blood together the cows meat also, probably the results would have been different.

    This test unfortunately do not acknowledge the shark species that is responsible for most human shark attacks, namely great white sharks. Great whites live off of fur seals, wich are indeed mammals. The test should have been done on great white sharks
