Like other acorn barnacles, S. cariosus is a filter feeder; when it is under water, the moveable terga at the apex part, and the cirri are extended to feed. When above water, the terga shut tightly for protection and to prevent desiccation. Small barnacles are sometimes "bulldozed" off the rock by the limpet Lottia digitalis while it is grazing ...
Like other acorn barnacles, M. tintinnabulum is a filter feeder. Specially adapted legs called cirri are extended through the opening at the top of the shell and are waved about at right angles to the flow of water past the shell. Food particles are caught by these, and the cirri are periodically withdrawn into the shell and the food scraped ...
Barnacle adults are sessile; most are suspension feeders with hard calcareous shells, but the Rhizocephala are specialized parasites of other crustaceans, with reduced bodies. Barnacles have existed since at least the mid-Carboniferous, some 325 million years ago. In folklore, barnacle geese were once held to emerge fully formed from goose ...
Black soldier fly larvae produced as animal feed. Insects as feed are insect species used as animal feed, either for livestock, including aquaculture, or as pet food. As livestock feed production uses ~33% of the world's agricultural cropland use, insects might be able to supplement livestock feed. They can transform low-value organic wastes ...
It is basically cone-shaped but can assume a more tubular shape in a crowded colony. Like other sessile barnacles, as an adult C. stellatus is a suspension feeder that stays in its fixed shell and uses its feathery, rhythmically beating appendages – actually modified legs – to draw plankton and detritus into its shell for consumption.

S. balanoides feeding, Upernavik, Greenland. Semibalanus balanoides is a filter feeder, using its thoracic appendages, or cirri, to capture zooplankton and detritus from the water. If there is a current, then the barnacle holds its cirri stiffly into the flow, but when there is no current, the barnacle beats its cirri rhythmically. Plankton ...
Under the new program, farms with herds that test negative for three consecutive weeks using bulk tank milk samples will be able to move cattle without additional pre-movement testing, USDA said.
Krill feeding in a high phytoplankton concentration (slowed by a factor of 12). Filter feeders are aquatic animals that acquire nutrients by feeding on organic matters, food particles or smaller organisms (bacteria, microalgae and zooplanktons) suspended in water, typically by having the water pass over or through a specialized filtering organ that sieves out and/or traps solids.
