This is underwater footage captured by Eaglehawk Dive Centre in Tasmania, Australia. This may look like a large inflatable tube but it's actually called a pyrosome, which consists of hundreds of thousands of animals called zooids embedded in a gelatinous tube that eats by sucking in water, filtering small particles, and blowing waste back out which is also which moves the colony albeit slowly. When this process pauses the colony can sink 1640-2295 ft below the sea. The creature's name means "fiery body" which comes from its bioluminescence, a bright blue-green glow that can light up the colony when disturbed. These "cylinders in the water" can sometimes grow to over 40 ft in length!
