| contents | Fig. 9. Vesicles of the caudal appendage of specimens from the Gullmarsfjord (A,C,E,F), North Sea (B,D) and White Sea (G,H,I), SEM images. A. Caudal view on the caudal appendage with numerous vesicles (ve). Dotted circle shows hollow stem of the caudal appendage. B, C. Examples for vesicles with irregularly scattered spinulets (arrows) on the surface and apical spinulet crown (dotted circles). D. Higher magnification of spinulet crown with similar sized spinulets. E. Higher magnification of spinulet crown with large median spinulets (dotted circle). F. Higher magnification of the tip of a large spinulet with five tubular receptor structures (arrowheads). G, H, I. Examples for spinulets with one (G), two (H) and three (I) tubular receptor structures on the tip. Further abbreviations: pw, posterior warts; rp, ring papillae. Scale bars: A = 500 μm; B,C = 200 μm; D = 20 μm; E = 50 μm; F = 10 μm; G = 5 μm; H, I = 2 μm. |
