What does a jellyfish use its tentacles for?
Jellyfish tentacles have a variety of jobs. Their main purpose is to capture food. Usually they trail behind the jelly to fish for prey.

The tentacle then contracts and draws the prey towards the mouth of the jellyfish, where oral arms push the food into the oral cavity for consumption. Tentacles sometimes are also used to aid locomotion, grasp onto substrates, and ward off enemies.
