Jellyfish do not have legs. Instead, they have an umbrella-shaped main body called the bell, from which long, trailing tentacles hang underneath. These tentacles are used for movement and capturing prey, but they are not legs in the traditional sense

. In summary:

• Jellyfish have a bell-shaped body.
• They have tentacles hanging from the bell, not legs.
• Tentacles are used for stinging prey and locomotion by pulsating the bell.

Therefore, jellyfish have zero legs.
