The opposite was true for Pagurus since response intensity, but not initiation, was suppressed. Both Panulirus and Podochela typically move long distances while grazing. Their assessments of prey quality and density are likely to occur on the patch-level of resource organization, where a "stop and feed" rule is most advantageous. Pagurus, on the other hand, is a microphagous detritivore that is active yet limited in mobility due to its small size. Given the limita- tions in the patch-selection ability of Pagurus, variable ingestion rates may be the most important animal response affecting feeding energetics. An optimal foraging model predicts that the net time rate of energy gain is maximized when benthic depos- it- and suspension-feeders covary ingestion rates positively with food value (Taghon, 1981). This is because such animals are unable to sample their environments and hence to choose among food items to the same degree that highly mobile predators.
