The jellyfish is a very unique animal, here are some of the things that make them what they are:
- They have little control over their movement, and free-float most of the time. But in order to move up and down,
they use their hydrostatic skeleton. The hydrostatic skeleton uses water pressure to contract their muscles.
- Jellyfish do not have a respiratory system, because their skin is so thin. They get oxygen through diffusion.
