image of Behaviour

1. Adult Pilumnus sayi conceal themselves in or under colonies of the bryozoan Schizoporella pungens, and concentrate their activity there. 2. Contests for possession of colonies involve 11 acts, 6 of which are modal action patterns (MAPs). The contests occur at close range (within 2 body widths) and are brief (median of 8 steps/encounter). 3. Larger crabs win most contests while sex has no effect on outcome and residency has little effect. Furthermore, the number of acts per encounter is negatively correlated with the size difference between crabs. 4. Escalation of violence occurs during contests, with MAPs involving force occurring later in the contest. 5. Either contestant is equally likely to escalate the violence but the larger crab is more likely to continue it at the higher level.
