Table 3 in Taxonomy of three species of the genus Spinoncaea (Copepoda, Oncaeidae) in the North Pacific Ocean with focus on morphological variability

Table 3. Variation in morphometric traits for three species of Spinoncaea (both sexes, including form variants of female S. ivlevi) from three locations in the Pacific Ocean (WP = western equatorial Pacific; EP = eastern equatorial Pacific; KS = Korea Strait; n = number of specimens examined) Abbreviations: A2 = antenna; AS = anal somite; CR = caudal ramus, for numbering of setae see Fig. 2C; DES = distal endopod segment; DS = distal spine; G(D)S = genital (double-)somite; in = inner margin; out = outer margin; L = length; PGS = postgenital somites; Pro = prosome; Uro = urosome; W = width.
