The study of marine plankton has traditionally focused on those or
ganisms that appeared to have obvious ecological significance in un
derstanding the major patterns of biological productivity, trophic
relations, community structure, and the dynamic interaction of
living things with the physical environment. Not infrequently, this
thrust has centered on the apparently most abundant and/or larger
members of the plankton community, including significant primary
producers such as the diatoms, nonthecate algae, and flagellates,
or the major con sumers--copepods, gelatinous metazoa, and other
abundant metazoan invertebrates. Consequently, some of the less
well recognized but also abundant microzooplankton have been given
less attention. The radio laria, although widely studied as fossils
by micropaleontologists, have in modem times. This is la been
relatively neglected by biologists mentable given their widespread
distribution in the oceans, remarkably complex form, and not
infrequently localized abundance. Their diver sity of form,
encompassing solitary species of microscopic dimensions and
colonial species as large as several centimeters or more,
challenges us to explain their evolutionary origins, explore their
structural-func tional correlates, and comprehend the ecological
basis for their wide spread occurrence in all oceans of the world
fromihe greatest depth to the surface of the sea. Their intricate
and aesthetically pleasing skeletons of enormous variety and
fine-detailed design formed from amorphous silica (opaline glass)
offer a unique biomineralized product that defies immediate
biological explanation."
