"(But what about Picnopodia. They are still there and healthy. How many urchins do they eat?)"

Good question. I don't know.

"Then there are the urchin barrens that no one has figured out (as far as I know so far). I will break purple urchins in urchin barrens as I swim."

The science project that Wayne's daughter did seems to agree with you that urchins do not instinctively attack the holdfast. Some have stated that breaking urchins up causes them to multiply or is this a falsehood???
