DETRITUS..ASSUMPTIONS NOT MUCH FIELD OBS.. KATTAGAT.. OBS IN AQ SHOW IT BURYING BODY IN MUD W INTRO MOVING BRISKLY OVER BOTTOM... VARY IN SIZE \& SHAPE.. 1.5>5X TRUNK; WHEN BOTH SPP PUT TOGETHER OVERNITE ONE PROC HAD PIERCED MUSCULAR VENTRAL SURFACE ... ONLY BODY VISIBLE OUTSIDE THE APHRO \& WHEN BY FORCE THE GOLF WAS HAULED OUT IT WAS SEEN THAT A PROBOC OF AT LEAST 3 CM HAD BEEN INTRODUCED INTO THE BODY OF APHROD. NEXT DAY A GOLF WAS OBS PENETRATING THE DORSAL MAT OF ANOHTER APHROD BUT IN THIS CASE THE INTRO WAS NOT INTRODUCED INTO POLYCH.; IN 55 \& 56 MORE OBSERV. ON LARGER SCALE REGULAR PENETRATION OF PROB INTRO. INTRODUCED INTO BODY CAVIT. OF APHRO. AUTHOR HAS WATCHED PROCESS OF INTRODUCTION - 30-35 TIMES; SOME CHEMICAL SENSE INVOLVED - INTROV.; *INTRO , BY A SLIIGHT INVAGINATION OF ITS DISTAL PARTS FIXED ITSELF BY SUCKING TO A BRISTLE OR TO THE VERY SURFACE OF THE POLYCHAETE. IN A FEW MINUTES THE GOLF WOULD PIERCE THE BODY WALL \& INSERT ITS PROB. WHILE BEING DRAGGED ALONG... AFTER 10 MINUTES ATTACHED BUT AFTER 30 MINUTES BY ITSELF...? SUCKING... TEMPORARY ONLY (SEE F4) PARASITE MAY EASILY PENETRATE SURFACE ANYPLACE - PREFER THRU LATERAL PARTS THRU GOLDEN BRISTLES; REASON MAY BE THIS IS MOST EASILY ACCESSABLE .. OR MOST EASY TO PENETRATE... REASONABLE TO ASSUME THAT THE OPENINGS OF THE NEPHR MIGHT STIMULATE SENSES OF SIP. NO EVIDENCE FOUND. CROWN OF TENTACELS OF GOLF WHICH SEEM TO MAKE IT LESS SUITABLE AS A PENETRATING INSTRUMENT. A PROB IN THE ACT OF INTODUCING IS NEVER FULLY EVERTED , SOME INVAG, ... SLENDER THREADLIKE POINTED SHAPE WHICH ALLOWS IT TO PIERCE THE BOSY WITHOUT DIFFICULTY. A FEW EXPERIMENTS WITH FRESH GOLF BROUGHT INTO CONTACT WITH OTHER SPP OF POLYCH - NO RESPONSE; APHRODITE NOT SEEN TO ATTACK GOLF EVEN THO IT IS A PREDATOR... THUS PROVED TO BE A TEMP. PARA.
