Here is an image of the original frag. I was really sad to lose it since it had such amazing color. The polyps were bright red-orange and the flesh ranged from banana yellow to almost sky blue.
Sample prep on this sample was similar to the Pocillopora sample. Images were acquired on a Hitachi 4800 Field Emission Gun SEM. The skeleton has some interesting structure:
Here's where a polyp would come from:
And the tip of one of those tines from the polyp area:
I zoomed in a bit on the crystal structure of the skeleton (from about the middle of the above pic):
Here's another area of the skeleton that I zoomed in on. There are some very different structures here:
Check out these spherical features I found. ...who'd of guessed?
