Shark..um..Feces..

My friend says that the jelly stuff you find on a beach is shark feces.

I say that they are jelly fish.

who is right?

You are…sort of.
A true jellyfish is the kind with the bowl and stinging tentacles underneath.
I assume you are taking about those dollops of jelly the size of the palm of your hand…those creatures ate technically called SALPS; they don’t sting.
