||Using a Zeiss compound microscope equipped with Nomarski optics and a Cohu video camera researcher downloaded an image of the worm to a Macintosh computer. Projected area was measured twice for each worm and the average recorded as worm area using a digital image analysis program (NIH Image 1.41). Measurement validity was checked by having different investigators independently measure worm and cell size without knowledge of the temperature at which the organisms had been reared.
||egg size is dependent on temperature, range given is from worms grown at 20°C to 10°C
