Crown of Thorns... yuck! I know how deadly to the coral that thing is, so when I see one, I spear it and cut it into many small pieces and leave it in the ocean for the fish to eat.

Do you also break the central disc in pieces? http://oceanlink.island.net/ask/echino.html#anchor362230

No. I have learned something today.

I understood that a starfish will regenerate from anybody part. In fact, in my daughter's high school marine biology course they were taught that if you cut up a star, put the pieces in a blender with sea water, make a slurry of the stuff, then allow it to sit in a viable sea water aquarium, the slurry would clump and then regenerate into billions of stars.

BTW, I would NEVER cut up a crown and leave the pieces in the water. I would spear them, collect them in a bag and leave the bag up on shore in the hot sun. Crown of Thorns decimate coral in a short amount of time. I've seen that personally.
