Water Flea (Daphnia)

A daphnia and its offspring

A Water flea (Daphnia) was photographed in fresh water. The specimen began to give birth before Spike could press the shutter release but, as luck would have it, the 'newborn' briefly returned to the field of view before swimming away. The photomicrograph was captured with Rheinberg illumination utilizing a blue central filter. The photomacrography equipment consisted of a Zeiss Tessovar zoom macro with a Bowen Illumitran transparency copier used as a flash light source in conjunction with a 2-inch aspheric condenser.
