Abstract
Opioids are known to influence feeding behaviour in the land snail. We have found this to be the case in the pond snail Lymnaea stagnalis, i . e. morphine increases while naloxone decreases food consumption. Evi dence is presented that the feeding program is influenced by opiates i ndirectly. The endogenous opioid system seems to control directly a de fensive fixed motor action accompanied by an arrest of feeding activit y.
