摘要:

Dense aggregations of large ovigerous female rock lobsters,Jasus edwardsii,observed by divers at several places around central New Zealand, are described. Such aggregations are typically seen in late winter in areas of strong tidal water movements, and in the absence of suitable shelter they take the form of defensive circles and heaps. We suggest that this behaviour may facilitate rapid dispersal of newly hatched larvae.
