[Coral-List] What eats Diadema?

[John Bruno]

Thanks to everyone who sent or posted their observations, videos, references, etc of other Diadema predators.  A combined list from this input, in no particular order, of known predators of Diadema includes: snapper, jacks, porcupinefishes, trunkfishes, grunts including black margate and white grunt, porgies, triggerfishes, pufferfish, large wrasses, parrotfish, octopuses, lobsters, several large gastropods, e.g., Triton’s trumpet snails and helmet shells (Cassis), small crabs (which eat juvenile Diadema), permit, saucereye porgy, southern stingray, hogfish, sea stars, e.g., Culcita and Oreaster, and zebra Moray.  

I archived most of the comments and posted a link to Bryce Groark's killer video of a zebra moray attacking a Diadema here:   http://www.climateshifts.org/?p=4302
