Frequency of observations of interval duration between conclusion of egg deposition and "Peristaltic arm flare" behavior in fe- males of Sepioteuthis aiistralis (n = 257 intervals). Male agonistic contests The behavior of males throughout agonistic contests was consistent with the observations of Jantzen and Havenhand (2003b). Paired males spend considerable time positioning themselves between unpaired males (these attempting to displace paired males from their mate) and the paired fe- male ("Parrying"). "Parrying" is considered to be the very early stages of agonistic contests between rival males and was not associated with any specific chromatic body pattern components. As these contests intensified, rival males began "Fin beating" (described as "swimming fight" in Jantzen and Havenhand, 2003b). "Fin beating" occurred when both males extended their arms and tentacles and collided while swimming backwards. At this time both males showed "Dark mantle" and "Iridescent sclera" chromatic body pat- tern components. "Fin beating" was quite forceful between males, and the collision of mantles and fins was intense. In. Interval Duration (seconds) Figure 8.
