There has been widespread speculation about the factors which contributed to the mass mortality of North Sea harbour seals during 1988, and the threat that these factors pose to this and other marine mammal populations. We identify the questions which need to be answered before these speculations can be transformed into testable hypotheses and outline an epidemiological context for the preliminary evaluation of such hypotheses.
