Christie's Corner, Hurst Island, God's Pocket Marine Park, BC, Canada
Orange or grapefruit sized (some but not most are still smaller). They are soft to the touch, squishy and full of water like a sponge. I could tear it in half with my fingers and fingernails if I wanted to. You can squeeze the water out of them but they are pretty dense even with their porosity, and heavy (for their size) because of the water they hold. The top comes up to these funny spires and sometimes they are tubes. The bottom is flat and slightly rounded. I see them on low tides but it doesn't have to be an extreme low tides. All are bright orange.
Present on Tegula funebralis
I think / hope? Would love confirmation. Growing on its own on a dead bent nose clam shell
