Table 2. Descriptive statistics for measurements of eggs of 8 diphyllobothriidean species studied from natural (samples from same hosts are pooled).
Range and means are given in micrometers for the 3 parameters subjected to morphometrical studies. Details for individual samples are listed in Table 1. Measurements are in micrometers (μm).
