Figure 3 in Systematic affinities of Zygophylacidae (Cnidaria: Hydrozoa: Macrocolonia) with descriptions of 15 deep-sea species

Figure 3. Type material of Zygophylax abyssicola (Stechow, 1926). A, B, colonies with dichotomous branching patterns, the arrow in A indicates the lectotype; C, a polysiphonic hydrocaulus; D, three successive nodes (arrows) on a hydrocladium, each internode bearing a hydrotheca; E, an axillary hydrotheca; F, a hydrotheca with diaphragm and renovations, and a nematotheca (arrow) near the hydrotheca; G, a coppinia; H, an isolated gonotheca, whose apex bears two apertures; I, a gonotheca with dichotomously branched defensive tubes. From samples: ZSM 20040197, paralectotype [A (left colony), G]; ZSM 20040197, lectotype [A (middle colony)]; ZSM 20040726, paralectotype [A (right colony), D]; ZSM 20043538, paralectotype (B, E); ZSM 20043539, paralectotype (C, F); ZSM 20043542, paralectotype (H, I). A–I, Indian Ocean. A–I, light microscope images. Scale bars: A = 1 cm; B = 0.5 cm; C, D, G, I = 1 mm; E = 0.5 mm; F, H = 200 µm.
