As mentioned earlier, I'd never seen so many sharks on a flat. We saw several very large nurse sharks like this one up to about 8 feet long. Lots of 4-5 foot blacktips, which fortunately behaved themselves when they swam by a few feet away. The only shark that gave me any trouble all week was a small blacktip that repeatedly swam up aggressively near my feet. I stomped hard on the sand several times right by his nose before he finally went away.
