The positions of a specimen of .•Inthoplcitni elegantissima (the aggregating form) were traced from photographs taken during one aggressive episode, (a) The anemone is shown at rest (before contact with the non-clonemate) ; the arrow indicates the region that will come into contact with the non-clonemate. (b) Initiation: the anemone is shown just after contact with the non-clonemate; the relative retraction of the tentacles and a slight swelling of the capitulum (to the right) may be noted, (c)

(b) Initiation: the anemone is shown just after contact with the non-clonemate; the relative retraction of the tentacles and a slight swelling of the capitulum (to the right) may be noted, (c) Inflation: the white tips (stippled) of the inflating acrorhagi have become visible in the area adjacent to the tentacles receiving the stimulation; the shape of the column is notably different from that shown in Figure la. (d) Inflation : the acrorhagi in the area of stimulation are strongly inflated, appearing white at the tips (stippled) and transparent at the bases, (e) Movement of application: the in- flated acrorhagi are drawn upward and back away from the source of the stimulus, (f) Move- ment of application: the acrorhagi are sweeping downward and may, as in this case, con- tinue downward to the position shown in Figure Ig, or the movement may stop in the position shown here with the anemone leaning over the adjacent non-clonemate. (g) Movement of application: the acrorhagi have reached the bottom of their downward sweep and are being wiped against the body of the victim, (h) Release of ectoderm: acrorhagial ectoderm has been released from one of the acrorhagi which is now transparent (unstippled) at the tip where the ectoderm is missing; the ectoderm is shown clinging to a tentacle of the victim, (i) Recovery: the acrorhagi have deflated but the anemone has not yet fully recovered its preaggression posture; the column is still somewhat elongated and the capitulum is still swollen and somewhat elevated in the area proximal to the area of Please note that
