Muricidae is a family encompassing a wide range of molluscs.  Most of
the subfamilies have animals that have color patterns on the foot sides
and pedestal that repeat through the subfamily.
 
I was just looking (with a video camcorder)at a Pterynotus elongatus.
It has a pattern on the top of the foot, foot pedestal, and tentacle
groups that is tiled similar to a Cymatium.  I had never seen this
pattern on anything but a Cymatium before.  Does anyone know if other
species in the Pterynotus have a similar pattern.  If so, which.  We
have a limited line of Murex in Hawaii to compare this specimen to.
 
Aloha,
