English: Life history mechanisms for localization and dispersal of neustonic organisms (a) Some neustonic species lay eggs on floating objects and sometimes pelagic organisms (e.g., Halobates spp.), while others require surface floating objects for early life cycle stages (e.g., Dosima fascicularis [1]), still others may remain at or near the surface throughout a life cycle due to a dependence on endosymbiotic photosynthetic zooxanthellae (a hypothesis proposed by Larson for Velella [2]). (b) Neustonic organisms like Sargassum may proliferate in one region (large circle) and be transported by wind and/or currents to high-density regions of low proliferation (small circles) [3]. (c) Neuston may also occupy deep water for one part of their life history (a hypothesis proposed for Velella by Woltereck [4), and (d) these deep-water habitats may allow them to take advantage of counter currents for transport in the direction opposite surface currents (a hypothesis proposed for Velella by Savilov [5]).
