Anglers seek them around rocky headlands and sometimes in the surf near reefs. GHOST SHRIMPS (Callianassa californiensis) areerroneously called "crawfish" by dealers who sell them for bait. Long, thin-bodied, and translucent, they contrast withthe black mud inwhich they live. Sometimes they burrow a foot below the surface, where they turn around simply by rolling themselves up.
