Summary

Description
English: Life history mechanisms of neustonic organisms - (a) eggs

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]).
