Velarium


We just learned about the Jellyfish Statocyst.

Another part of some jellyfish is the Velarium.

For the box jellyfish, underneath the edge of the bell on the inside it folds in, kind of like a little shelf.
This makes it so that when they squish their bell to swim, it makes it like a torpedo and pushes water out faster than normal.

Because of this these are the fastest jellyfish in the world, and we already know they are one of the most dangerous because of their sting!
They can swim up to 20 feet per minute.
That's still not even one mile per hour, but for a stinging jellyfish that's pretty quick.
