Linkia study page 6

Who would have thought that such a tiny little snail could have done so much damage?  At this point, I'm not sure that the starfish was the only thing that this snail has been feeding on.  Considering where the opening was on the starfish, and how close to that hole the foot of the snail sat, knowing it was moving around in there....anything is possible. 

Here we have the hollowed out arm.  At this point I have used the pin and tweezers to remove all soft tissue that would come out easily. 

The blue arrow points to the hole.

The red arrow points to the hollowed our round (lump) where the snail laid.

Anything that shows up here with a yellow tint to it is fragments of the snail flesh.  It looks smooth, but in fact, each piece was a small "chunk" that lifted out of a grove, but not easily.

Outlined in green is what remained of the starfish flesh.

Outlined in blue are the "chunks" of snail flesh.

From another angle, the red arrow points to the starfish flesh and the blue arrows point to the remains of the snail.
