Table 6.
Morphometric data from Enchelyodon nodosus. Data based on mounted, protargol-impregnated (Foissner 1991, protocol A), and randomly selected specimens from a non-fooded Petri dish culture. Measurements in μm. CV – coefficient of variation in %, M – median, Max – maximum, Min – minimum, n – number of specimens investigated, SD – standard deviation, SE – standard error of arithmetic mean, x̄ – arithmetic mean
