A large percentage of oceanic zooplankton are transparent, some achieving almost
complete invisibility, and it is generally assumed that transparency is an important
method of camouflage in the optically featureless open-ocean environment. However, despite
the prevalence and presumed ecological importance of transparency, little is known about
this characteristic and how it is achieved.
This talk summarizes my research into the how and why of biological transparency and
includes field measurements of transparency versus wavelength at visible and ultraviolet
wavelengths, mathematical models of underwater visibility, and an analysis of the
ultrastructure of transparent tissues from an optical perspective.
