We just learned about the Lappet.
Another part of a jellyfish is the Rhopalium.
Remember we learned about the lappet that goes the bell and dents in on some spots.
The part where the bell dents in toward the middle is called the Rhopalium.
In these rhopalium are things that jellyfish can use to sense light and movement.
