Light microscopy

Small larval stages (i.e. nauplius, copepodids and chalimus I and II) were examined in a cavity slide under a cover slip. Lactic acid (87.5%) was used to aid in the clearing of the body tissues of larval stages, to enhance visualisation of gland structures without affecting the quality of staining, although this method could not be used as a permanent mountant (Huys & Boxshall, 1991).

Observations were made using an Olympus BH-2 compound microscope and photographs were taken using an Olympus C-35AD-2 camera.
