Question

The movement in the figure shown below is called ___ movement

Answer 1

Hydra are not always attached to the substrate and can move from one spot to another, either by gliding along on the basal disc or by somersaulting along. When somersaulting, they detach the basal disc and then bend over and place the tentacles down on the substrate. Looping is the most common type of locomotion in hydra in which hydra makes a ${180}^o$ angle while moving.
