This is a Supermacro view of Brain coral showing a colony of genetically identical polyps. A defunct tubeworm hole provides a secure dwelling for a resident Spinyhead blenny.

Measuring around 2cm long, the blenny lives most of its life in this abandoned hole. Darting out with lightning-fast speed, it captures prey that washes past on an ocean current. The upper reaches of its hollowed-out cylindrical home are comprised of dozens of bright yellow living animals. Deeper down, the walls of the tube are made from layers of dead polyps. The entire coral head may be a few hundred years old.
