Wholesale bitWholesale bit Third, and probably most important, only by study of both shell and animal can we ever arrive at a trite determination of what constitutes a valid species. Wholesale bitWholesale bit Although encountering a consistent westerly set, limited veliger distribution from the periodically proximal counter-equatorial current distinguishes the Phoenix Group as a western limit for most Indo-Pacific shell species. Oceanographic separation apparently prevents introduction of South American and Eastern Pacific species. Situated in the midst of the Phoenix Group, McKean Island lies approximately one hundred miles from its nearest neighbor, Gardner Island. Isolation by distance is perhaps not so significant as that imposed by the great depth of surrounding water, averaging 2800 fathoms on all sides. Idealized current flow and consistent dry climate characterize this isolation geologically. Ecologically, such forms of natural isolation create boundaries to various marine life, thus providing other marine life forms the opportunity to develop and interact in a unique environment the influence of which is emphasized by uniformity. Consequently, the prevalence, distribution and evolution of an established species can be studied with greater validity when these three variables are regarded as a sole function of a particular isolated environment; usually produced artificially by the restriction of scientific method, but in the case of McKean Island, more perfectly imposed by natural forces.
