There are two intriguing study topics concerning
the Haploporidae. The first is the evolution of displayed parasite host specificity. The second, inseparable from the first, is the
evolutionary events now reflected in the present distribution around the globe. The term ZOOGEOGRAPHY encompasses the whole of this
field of research.
The clickable link Zoogeography enables the presentation of a 37-panel slideshow detailing an
examination of the theoretical possibilities accounting for the evolution and distribution of species of Haploporidae.
Each slide is in view for ten (10) seconds. The viewer may terminate the slide show at any point by use of the "back arrow" of the
Internet browser to return to the panel to which the slideshow is linked. Each panel is displayed at 1050x800 pixels, and is so sized to display
without distortion on almost all viewing screens. Only very old monitors, or those set to a coarse resolution for some special need, will not
be presented with fidelity. An alternate display size presentation of 800x600 pixels is available at this linked location:
