Locomotion
- Medusa move by taking in water in their gastrovacular cavity and push it out, like jet propulsion, to move.
- Most medusa can not actually produce enough power though to fight currents so they can be carried by these currents and washed up on beaches. (www.britannica.com)
- On rare occasions some sea anemones that are attached to firm substrata can move across slowly on their pedal disks or detach completely and swim using their tentacles to another location. (www.britannica.com)
