If I'm not mistaken, I'm pretty sure Mark Johnson found a huge, live
Cassis madagascariensis while diving off North Carolina. I saw it in one
of his shell show exhibits. I don't remember the depth he listed on the
data tag.  My mom found a large, beat up specimen, in 1989 in the sound
waters of Cape Lookout.

But I suspect the examples I'm coming across are eroding out of the
dunes. I just saw a fragment comprised of the entire ventrum exposed in
the surface of the dune facing Cape Lookout on Shackelford Island. Wish
I'd brought a camera. That said, I wouldn't be totally shocked if
someone does pull a live Cassis out of shallow waters some day.

Beaufort and Harkers and found Neosimnia uniplicata and seafan in the
drift and trash. These seem really exotic to me for temperate climate
(not the trash).
