There are two ways in which jellyfish move through the water. Some swim, using jet propulsion, and some attach themselves by a stalk to other material, such as seaweed. Both types are referred to as zooplankton (animal drifters), because their movement is strongly influenced by the ocean's current. Even jellyfish capable of jet propulsion are not strong enough swimmers to counter the power of the current and waves.
Jet propulsion in jellyfish is possible because of special muscles called coronal muscles, embedded on the underside of the bell, which push water out of the hollow bell. As water is pushed in one direction, the jellyfish moves in the opposite direction.
Without a brain or eyes, jellyfish rely on nerve cells to help them move and react to food or danger. Sensing organs tell them whether they are heading up or down, into the light or away from it.
They remain balanced in the water with help from special sacs, located on the bell rim. When a jellyfish shifts too far to one side or the other, the sacs stimulate nerve endings to contract muscles that reorient the jellyfish in the correct direction
