No, not Bear ... the thing in Junior's hand. That is a moon snail out hunting. Moon snails completely cover their shell when they are out, so all you can see is the muscular foot (did you know ... okay, I'll stop ... I promise) that he uses to creep along.
One last thing from that night walk ...
It's not a mollusc, but this seastar at night on the sandspit is a bit of slow motion grace that you might want to view since you couldn't come along.
(Did you know many types of seastars extrude their stomach to feed?)
Oops ... that just slipped out.
