Minute organisms that float or swim on surface water or on a surface film of water.



the organisms that attach themselves to the surface film of water and move on either the top of the film (supraneuston) or the underside (infraneuston). The neuston includes protozoans, unicellular algae, water striders, Gyrinidae (whirligig beetles), gnat larvae, some Cladocera (water fleas), Pulmonata, and other small, for the most part freshwater, organisms. The marine infraneuston also includes inhabitants of the top of the water (0–5 cm), which occupy that region at all times or only at night (small crustaceans, fish fry).

Clearly, by the start of the 21st century the myth of excessive rarity in regard to Hermatobates (Herring, 1958) had been conclusively dispelled, and it is now understood that members of this genus are typical components of marine neuston assemblages throughout the tropical Pacific and Indian Oceans, and to some degree in the Caribbean as well, and that they can be effectively sampled by skilled collectors.
