ABSTRACT
The presence of numerous specimens within the studied Echinocyamus populations, many of which show borehole infestation, allow detailed statistically based comparisons. Investigations are done with respect to borehole morphology and frequency, site selectivity patterns, frequency of multi-predatory events, the prevalence of predation with respect to general population structures, the distribution of predation with respect to general depositional environments and so on. The data is put into context with predation data on echinoid prey through time.
