Pyrosomes, also known as sea pickles, can be as big as a shark or a small whale! Pyrosomes are giant, worm-like creatures that are just a tube of jelly with even tinier animals called zooids in them. The zooids help the sea pickle move through the water and also collect food. Sea pickles can be as small as a human thumb to as big as 60 feet long!
