In this final chapter, our aim is two-fold. Firstly, we refine a method for choosing pertinent scientific questions. Secondly, we present some suggestions for interdisciplinary benthic biology/hydrodynamic questions which occur to us. If the latter questions prove to be of no, or less than riveting, interest to those active in benthic biology in the future, then we may console ourselves with the knowledge that our readers should be able to choose pertinent questions for themselves. We firmly believe that the creative natural scientist is rooted in extraordinary powers of observation so that she/he can

and, by this, be motivated enough to determine how it works.

To recapitulate what is presented in the preceding six chapters (Table 9.1): Each of the subjects reviewed is variable in the attention or success of the studies that are focused on it. This is clearly shown by the rank order of the number of hypotheses associated with each chapter (Table 9.1). Also shown is the associated dominant theory for each subject.

This may also be the best point at which to summarize our scientific judgement on hypotheses dealt with in Chapters 3 through 8 (Table 9.2).
