 * __HOW DO JELLYFISH SWIM?__**

Answer the question below, append new answers to the top of this page. _ __Response 1:__ Jellyfish swim to get around. For a jellyfish, this means opening and closing its bell, it is kind of like the way you open and close an umbrella. A jellyfish has a ring of muscle around its bell. When a jellyfish tightens this muscle the bell closes. This pushes water inside the jellyfish out, shooting the jellyfish forward. As the muscle relaxes, water goes back into the bell. Even though jellyfish can swim, ocean currents often control where they go. Jellyfish float, drift, and sink with the ocean currents. Ocean currents help jellyfish move around. But currents can also cause a lot of damage. Jellyfish are very fragile. Strong currents during storms can tear a jellyfish’s bell or break off its tentacles. Currents can also leave a jellyfish stranded on a beach.

__Additional Responses:__

Considering that jellyfish are a midsized marine species that are shaped like a mushroom. They are limited to a lot of movement, plus they have a pretty week frame. So to swim, these creatures have to use the power from their rounded body called (A bell). The bell has a lot of force and shoots out the water usually downward, which keeps the animal upright and propelling it usually in a vertical direction, the animal has no bones so the movement is very vibrant and quick. They squeeze their bodies inward; as if you were to cup your hand then open it. They have a strong propelling force, which pushes them in a vertical direction. It’s sort of like floating with force.
