Feeding
A non-selective and opportunistic predator, Urticina crassicornis, may feed on crabs, sea urchins, mussels, gastropods, chitons, barnacles, fish, and sometimes sea stars and stranded jellies. A peculiar prey, the sun star, Pycnopodia helianthoides commonly known as the "Sunflower Star", is found in Washington state and has a size much greater than U. crassicornis, sometimes ranging up to 5 ft. in length. This anemone exhibits both intracellular and extracellular digestion. Food is caught within the tentacles which then move the prey towards the oral disc.

“Injections ... are the best thing ever invented for feeding doctors.”
—Gabriel García Márquez (b. 1928)
“Man may have his opinion as to the relative importance of feeding his body and nourishing his soul, but he is allowed by Nature to have no opinion whatever as to the need for feeding the body before the soul can think of anything but the body’s hunger.”
—George Bernard Shaw (1856–1950)
“The will to domination is a ravenous beast. There are never enough warm bodies to satiate its monstrous hunger. Once alive, this beast grows and grows, feeding on all the life around it, scouring the earth to find new sources of nourishment. This beast lives in each man who battens on female servitude.”
—Andrea Dworkin (b. 1946)
