Small organic particles are moved into the mouth by the tube feet.

"Sensors do not detect any traces of organic particles," reported Data.

Abandoned mucus houses sink to the deep, collecting organic particles during their descent.

Brachiopods have probably always filter-fed, living off small organic particles brought on currents.

In surface waters, dioxins are bound to organic and inorganic particles.

The creatures were still grazing placidly along the stream of organic particles.

They appear to be ingesting the organic particles that drift through the sea.

Cilia on the tentacles cause currents in the water and organic particles are caught as they float past.

"Now, while Data can still detect the organic particles of their trail."

Less water flowing into the lakes also means that fewer organic particles flow into them, the study found.
