WOW!! That is impressive. Do you think this is a large species, or
that these big ones are abnormal?

Siphonariids do not grip tenaciously. Unlike limpets, they can
usually quite easily be pulled off by hand. And if they do hold on
tight, you can slip a blunt knife under the foot (I like to dig into
the rock under the foot, so as not to injure the animal and cause it
pain).

Yes, I would like to se images of this, please.
