Bonferroni confidence interval analysis to evaluate age selection of preyed
upon a total of 18 species (15 prey categories) across the three studies (see Table 2).
Medium and large Daphnia, however, may not have escaped detection, and accordingly, were preyed
upon at a significantly higher rate.
However, British paleontologists had previously unearthed a spinosaur that appeared to have preyed
upon or scavenged the remains of a juvenile Iguanodon, a herbivorous dinosaur.
Use of a retreat may reduce energy expenditure, or decrease the spider's chance of being preyed
upon or injured (see Uetz 1989).
