They inhabit the shorelines where they are most commonly found clinging to smoth places on the rocks, pounded by the surf and exposed between the tides. They are valued by the Hawaiians who pry them off the rocks for the food which they offer. The meat is considered a great delicacy and sells for upwards of $15.00 per pound.
