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.

Red hot diving at Roca Partida

Measuring 91 metres by 45 metres by 34 metres high, the island is actually the lava plug from a volcano that gradually eroded away around it. It is an amazing 11,000 feet deep around the volcano and we gingerly anchor the Nautilus Explorer in 245 feet of water very close to the lava tube. Roca Partida is a “magnet” for mantas, sharks of all kinds, wahoo, tuna, dorado and all other manner of sub-tropical fish.
