Figure 3 in Observations of multiple pelagic egg masses from small-sized jumbo squid (Dosidicus gigas) in the Gulf of California
Figure 3. (a) Distribution of Dosidicus gigas embryo and paralarval stages found in six egg masses. The variability in the number of eggs from each mass was due to sampling variability. (b) Estimated age (duration since spawning event) of egg masses based on modal stage. Stages and corresponding ages are based on Watanabe et al. (1996). Note that the May 29 #2 and May 30 #2 masses are slightly older than May 28 #1 even though they have less developed embryos because the Stage 17 age estimate is from 20 rather than 23°C incubation and thus a slower developmental rate. (c) Estimated time the egg masses were spawned based on age.
Facultative chemosynthesis in a deep-sea anemone from hydrothermal vents in the Pescadero Basin, Gulf of California
<p><span><i>Background</i></span></p> <p><span>Numerous deep-sea invertebrates have formed symbiotic associations with internal chemosynthetic bacteria in order to harness inorganic energy sources typically unavailable to most animals. Despite success in nearly all marine habitats and their well-known associations with photosynthetic symbionts, Cnidaria remain without a clear dependence on hydrothermal vents and chemosynthetic bacterial symbionts specifically.</span></p> <p><span><i>Results</i></span></p> <p><span>A new chemosynthetic symbiosis between the sea anemone <i>Ostiactis pearseae </i>(Daly & Gusmão, 2007) and intracellular bacteria was discovered at ~3700 m deep hydrothermal vents in the southern Pescadero Basin, Gulf of California. Unlike most sea anemones observed from chemically-reduced habitats, this species was observed in and amongst vigorously venting fluids, side-by-side with the chemosynthetic tubeworm <i>Oasisia </i>aff.<i> alvinae</i>. Individuals of <i>O. pearseae </i>displayed carbon, nitrogen, and sulfur tissue isotope values suggestive of a distinct nutritional strategy from conventional Actiniaria suspension feeding or prey capture (average d<sup>13</sup>C -29.1‰, d<sup>15</sup>N 1.6‰, and d<sup>34</sup>S -1.1‰). Molecular and microscopic evidence confirmed the presence of intracellular SUP05-related bacteria housed in the tentacle epidermis of <i>O. pearseae</i> specimens collected from 5 hydrothermally-active structures within two vent fields ~2 km apart. SUP05 bacteria dominated the <i>O. pearseae</i> bacterial community (64-96% of the total bacterial community based on 16S rRNA sequencing), but were not recovered from other nearby anemones, and were generally rare in the surrounding water (< 7% of the total community). Further, the specific <i>Ostiactis</i>-associated SUP05 phylotypes were not detected in the environment, indicating a specific association. Two unusual candidate bacterial phyla (the OD1 and BD1-5 groups) also appeared to associate exclusively with <i>O. pearseae</i> and may play a role in sulfur cycling.</span></p> <p><span><i>Conclusion</i></span></p> <p><span><i>Ostiactis pearseae</i> represents the first member of Cnidaria described to date to have a physical and nutritional alliance with chemosynthetic bacteria. The facultative nature of this symbiosis is consistent with the dynamic relationships formed by both the SUP05 bacterial group and Anthozoa. The advantages gained by appropriating metabolic and structural resources from each other presumably contribute to their striking abundance in the Pescadero Basin, at the deepest known hydrothermal vents in the Pacific Ocean.</span></p>
