Feeding reactions were studied by Bozler (1926), where a piece of food was given to the marginal tentacle, the tentacle contracted quickly. There was a slow contraction of the coronal muscle which brought the tentacle nearer to the mouth.
In Bozler's (1926) study on feeding reactions, a piece of food was presented to the tentacle's border, triggering rapid contraction. Subsequently, the coronal muscle contracted gradually, drawing the tentacle closer to the mouth.
