Feeding Habits
The animals have a mouth with special jaws (Aristotle's lantern) located on the bottom (oral) surface. Their preferred diet is seaweeds, kelp and algae, which they scrape off and tear up from the sea floor. During larval development, urchins use bands of cilia to capture food from the water column.

Famous quotes containing the words feeding and/or habits:
“How did you feel feeding doughnuts to a horse? Had a kick out of it, huh? Got a big laugh. Did you ever think of feeding doughnuts to a human being? No!”
—Robert Riskin (1897–1955)
“Almost always tradition is nothing but a record and a machine-made imitation of the habits that our ancestors created. The average conservative is a slave to the most incidental and trivial part of his forefathers’ glory—to the archaic formula which happened to express their genius or the eighteenth-century contrivance by which for a time it was served.”
—Walter Lippmann (1889–1974)
