If Dr. Seuss engineered a tube worm, I suspect he might have come up with
something like these two Surpula vermicularis. A classic, example of an
animal that is ubiquitous but seldom photographed, surpulids retreat into their
calcerous tubes should a would-be photographer so much as cast a shadow in their
vicinity. Not surprisingly, shots like this one can be something of an extended
project. I'll likely return to this spot to work on it some more.
