Jellyfish Statocyst

We just learned about the Ocelli.

Another part of a jellyfish's body is Jellyfish Statocyst.

We've learned about the Octopus Statocyst before, and it's pretty much the same thing.

The jellyfish has a small sac in it's body, with small hairs on the inside, and a hard ball inside.
When the jellyfish moves around, the ball rolls around and touches the hairs.
These hairs tell the jellyfish which way is up or down and which way they are swimming.
