It sounded like from the popular accounts that the corals only did that
when the water they were in had zero nutrients in it, they didn't do it in

waters.  That's what it sounded like at least.

Scientists size up human predatory footprint
Humans are the ultimate predators, trapping, hunting, or otherwise
exploiting 15,000 species of vertebrates—300 times more species than
jaguars and 113 times more than great white sharks.
