| contents | <p><b><i>Aequorea</i> spec.2</b></p><p>Fig. 42</p><p><b>Material examined:</b> BFLA4013; 1 specimen; 17-DEC- 2018; preserved in alcohol for DNA extraction; 16S sequence MW528639.</p><p><b>Observations:</b> Small, juvenile <i>Aequorea</i> medusa, 7 mm, no gonads. Stomach diameter 0.3 of bell diameter. About 30 broad radial canals. Tentacles not all visible, approximate range 18-30. Tentacle bulbs conical, not inflated, without keel or white abaxial line, without abaxial spurs.</p><p><b>16S data:</b> The single sequence proved to be quite closely related to <i>Gangliostoma guangdongensis</i> Xu, 1983 (Fig. 37). The base pair differences in the pairwise aligned sequences were 3.6%.</p><p><b>Remarks:</b> We found only one specimen of this lineage and it was too immature for being identified. Additionally, the animal was attempting to swallow a much lager ctenophore and was thus quite distorted. Its 16S sequence resembled the Chinese <i>Gangliostoma guangdongensis.</i> The genus <i>Gangliostoma</i> is distinguished from <i>Aequorea</i> by a papilla situated at the base of the stomach and between each pair of radial canals. This feature is not well documented and it is unclear what it is. No such papillae could be seen in the present specimen.</p> |
