Dominance and a large black manta ray

Interestingly, one group of divers reported observing behaviour that reminded me very much of the great white sharks of Guadalupe Island. Last season we would see 2 white sharks swim side-by-side as if they were measuring their respective lengths against each other. The smaller animal would then peel off into the blue. The larger animal presumably being the dominant animal. I “think” we saw the same thing with 2 giant manta rays. 2 animals (a chevron manta and a larger black manta) swam in tight formation in a vertical pattern. The smaller chevron then peeled off and disappeared into the blue. Presumably, just like the white sharks, the large black manta ray established it’s dominance and got to hang out with a human.
